Parsing XML in C# from xml REST POST webResponse - c#

I'm trying to parse an XML response from a REST endpoint. I am using a POST request (if that's relevant). I can't get the document to parse correctly. I've researched this all over stack overflow, and none seem to be applicable to my response. How can i parse my XML? I've tried all of the below:
Using XDocument:
Stream postData = resp.GetResponseStream();
StreamReader reader = new StreamReader(postData, Encoding.UTF8);
string result = reader.ReadToEnd();
var document = XDocument.Parse(result);
XNamespace ns = XNamespace.Get("http://www.w3.org/2005/Atom");
var items = document.Descendants("NameFirst")
.ToDictionary(i => (string)i.Attribute("Key"),
i => (string)i.Attribute("Value"));
Using nested for each with XElements:
Stream postData = resp.GetResponseStream();
StreamReader reader = new StreamReader(postData, Encoding.UTF8);
string result = reader.ReadToEnd();
XDocument document = XDocument.Parse(result);
XNamespace ns = XNamespace.Get("http://www.w3.org/2005/Atom");
string list = "";
foreach (XElement level1 in document.Elements("feed"))
{
foreach (XElement level2 in level1.Elements("entry"))
{
foreach (XElement level3 in level2.Elements("content"))
{
foreach (XElement entry in level3.Elements("Entry"))
{
list += entry.Attribute("NameFirst").Value;
list += entry.Attribute("NameLast").Value;
}
}
}
}
Using a concatenation of Descendant methods:
Stream postData = resp.GetResponseStream();
StreamReader reader = new StreamReader(postData, Encoding.UTF8);
string result = reader.ReadToEnd();
var document = XDocument.Parse(result);
XNamespace ns = XNamespace.Get("http://www.w3.org/2005/Atom");
var listOfFields = document.Descendants(ns + "feed").Descendants(ns + "entry").Descendants(ns + "content").Descendants(ns + "entry").Select(x => x.Elements().First().Value).ToList();
ResultLabel.Text = "";
foreach(String item in listOfFields){
ResultLabel.Text += item;
}
Using multiple Element methods:
Stream postData = resp.GetResponseStream();
StreamReader reader = new StreamReader(postData, Encoding.UTF8);
string result = reader.ReadToEnd();
var document = XDocument.Parse(result);
XNamespace ns = XNamespace.Get("http://www.w3.org/2005/Atom");
var listOfFields = document.Descendants(ns + "feed").Descendants(ns + "entry").Descendants(ns + "content").Descendants(ns + "entry").Select(x => x.Elements().First().Value).ToList();
var entry_ = document.Root.Element("entry");
var content = entry_.Element("content");
var entry = content.Element("Entry");
var fname = entry.Element("NameFirst").Value;
var lname = entry.Element("NameLast").Value;
ResultLabel.Text = string.Join(",", lname, fname);
My XML response:
<?xml version="1.0" encoding="utf-8"?>

You can deserialize the XML into easily accessible objects. Here's how to do it:
Create the objects that will hold your deserialized data:
You can easily do it by copying the XML you're getting from your REST endpoint then in Visual Studio go to Edit -> Paste Special -> Paste XML as classes
Once your classes are created you will get something like this:
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://www.w3.org/2005/Atom", IsNullable = false)]
public partial class feed
{
public feedTitle title { get; set; }
public string id { get; set; }
public System.DateTime updated { get; set; }
public feedLink link { get; set; }
public feedEntry entry { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
public partial class feedTitle
{
[System.Xml.Serialization.XmlAttributeAttribute()]
public string type { get; set; }
[System.Xml.Serialization.XmlTextAttribute()]
public string Value { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
public partial class feedLink
{
[System.Xml.Serialization.XmlAttributeAttribute()]
public string rel { get; set; }
[System.Xml.Serialization.XmlAttributeAttribute()]
public string type { get; set; }
[System.Xml.Serialization.XmlAttributeAttribute()]
public string href { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
public partial class feedEntry
{
public string id { get; set; }
public feedEntryTitle title { get; set; }
public System.DateTime published { get; set; }
public System.DateTime updated { get; set; }
public feedEntryContributor contributor { get; set; }
public feedEntryContent content { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
public partial class feedEntryTitle
{
[System.Xml.Serialization.XmlAttributeAttribute()]
public string type { get; set; }
[System.Xml.Serialization.XmlTextAttribute()]
public string Value { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
public partial class feedEntryContributor
{
public string name { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
public partial class feedEntryContent
{
public feedEntryContentEntry Entry { get; set; }
[System.Xml.Serialization.XmlAttributeAttribute()]
public string type { get; set; }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.w3.org/2005/Atom")]
public partial class feedEntryContentEntry
{
public ushort EntryID { get; set; }
public byte CategoryID { get; set; }
public byte EventID { get; set; }
public byte GroupID { get; set; }
public byte ContactID { get; set; }
public byte AddressTypeID { get; set; }
public byte PinNumber { get; set; }
public object Password { get; set; }
public object PortalEmail { get; set; }
public string NameLast { get; set; }
public string NameFirst { get; set; }
public object NameTitle { get; set; }
public string NamePreferred { get; set; }
public string NameWeb { get; set; }
public object NameOther { get; set; }
public object NameInitials { get; set; }
public object NameSharer { get; set; }
public string GenderEnum { get; set; }
public string Birth_GenderEnum { get; set; }
public bool DirectoryFlagPrivacy { get; set; }
public object Position { get; set; }
public uint ID1 { get; set; }
public string ID2 { get; set; }
public object ID3 { get; set; }
public byte ID4 { get; set; }
public byte ID5 { get; set; }
public bool PhoneProcessToAccount { get; set; }
public byte PhoneChargeTypeID { get; set; }
public byte PhoneDisableValue { get; set; }
public byte PhoneRestrictValue { get; set; }
public string PhoneControlEnum { get; set; }
public string TaxExemptionEnum { get; set; }
public bool Testing { get; set; }
public uint timestamp { get; set; }
}
Then you can deserialize the XML into a feed object like the following:
using (var ms = new MemoryStream(Encoding.UTF8.GetBytes("Your XML string here")))
{
XmlSerializer serializer = new XmlSerializer(typeof(feed));
feed feedObject = (feed)serializer.Deserialize(ms);
// Then you can access the xml content like you do with any object.
Console.WriteLine(feedObject.title.Value);
}

How do I deserialize an XML API response in ASP.NET?

I am working on a project that calls an API (using C# ASP.NET), and the API returns an XML document. I know how to deserialize an response in JSON, but am running into issues with deserializing an XML response. Currently I am getting the below error when attempting to deserialize the XML:
InvalidOperationException: response xmlns="" was not expected.
The error code displayed just the empty quotes in the error message. I have the code samples below, and I would greatly appreciate any constructive feedback or advice on making this better, and any advice on where I went wrong on attempting to deserialize this!
Here is the XML response from the API call (This API only returns either CML or a .csv):
<response xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.2" xsi:noNamespaceSchemaLocation="http://www.aviationweather.gov/static/adds/schema/metar1_2.xsd">

This is the code to call the API:
private static readonly HttpClient client = new HttpClient();
static async Task Main(string[] args)
{
client.DefaultRequestHeaders.Accept.Clear();
string baseUrl = "https://www.aviationweather.gov/adds/dataserver_current/httpparam?dataSource=metars&requestType=retrieve&format=xml&stationString=KMSP&hoursBeforeNow=2";
client.BaseAddress = new Uri(baseUrl);
HttpResponseMessage result = client.GetAsync(baseUrl).Result;
XmlSerializer serialObject = new XmlSerializer(typeof(MetarReport));
List<MetarReport> MetarCollection = new List<MetarReport>();
if (result.IsSuccessStatusCode)
{
using (Stream reader = result.Content.ReadAsStreamAsync().Result)
{
MetarReport metar = new MetarReport();
metar = (MetarReport)serialObject.Deserialize(reader);
MetarCollection.Add(metar);
}
}
// Test deserializer
foreach(var item in MetarCollection)
{
Console.WriteLine(item.rawText);
}
Console.ReadLine();
}
And this is the object I am attempting to deserialize the XML into

Retrieve XML column from DataBase with lines C#

I run query against DB which returns me 1 row 2 columns. Each column has XML(script) inside which I need to retrieve into (ideally string) and then execute against DB.
I need the retrieved string to have lines and formatting as if i would copy if from SQL management studio.
Part of XMLresult from SQL management studio I need this format. replacement: XXXXXX

Thanks for any advice.
So the key is to get the proper indentation?
In that case, I would recommend taking a look at the following SO thread:
Format XML string to print friendly XML string
The key is that you need indentation, which can be achieved through the XmlTextWrite.Formatting = Formatting.Indented option.
Use XML serializer. See code below
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
namespace ConsoleApplication193
{
class Program
{
const string INPUT_FILENAME = #"c:\temp\test.xml";
const string OUTPUT_FILENAME = #"c:\temp\test1.xml";
static void Main(string[] args)
{
string xml = File.ReadAllText(INPUT_FILENAME);
StringReader sReader = new StringReader(xml);
XmlReader reader = XmlReader.Create(sReader);
XmlSerializer serializer = new XmlSerializer(typeof(Message));
Message message = (Message)serializer.Deserialize(reader);
//write
XmlSerializerNamespaces names = new XmlSerializerNamespaces();
names.Add("q1", "XXXXXX");
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
MemoryStream stream = new MemoryStream();
XmlWriter writer = XmlWriter.Create(stream);
serializer.Serialize(writer,message,names);
byte[] buffer = new byte[stream.Length];
stream.Position = 0;
stream.Read(buffer, 0, (int)stream.Length);
string output = Encoding.UTF8.GetString(buffer);
}

XML not being serialised correctly into object

I am trying to serialise a piece of XML that is being returned from a third party API. However when doing so i am only retrieving part of the object upon serialisation. And only some of the values seem to exist. I thought this could be a input type problem, however all the types seem to be correct. I think it may have something to do with how my model is constructed.After debugging the code i have narrowed it down to be a problem with the conversion of the xml into the object.
C# CODE:
//[Route("api/AvailabiliyCheck/GetAvailability/{CSSDistrictCode}/{GoldAddressKey}")]
public EADAvailabilityDetails GetAvailabilityEAD([FromUri] string CSSDistrictCode, [FromUri] string GoldAddressKey)
{
//Load the request xml template
XmlDocument doc = new XmlDocument();
string path = HttpContext.Current.Server.MapPath("~/XML/Availability/GetAvailabilityEAD.xml");
doc.Load(path);
//Assign incoming paramaters to xml template
XmlNamespaceManager manager = new XmlNamespaceManager(doc.NameTable);
manager.AddNamespace("soap", "http://schemas.xmlsoap.org/soap/envelope/");
manager.AddNamespace("stupid_xmlns", "http://webservices.talktalkplc.com/NetworkProductAvailabilityCheckerService");
XmlNode CSSDistrictCodeNode = doc.SelectSingleNode("soap:Envelope/soap:Body/stupid_xmlns:GetAvailability/stupid_xmlns:request/stupid_xmlns:RequestDetails/stupid_xmlns:CSSDistrictCode", manager);
CSSDistrictCodeNode.InnerXml = CSSDistrictCode;
XmlNode GoldAddressKeyNode = doc.SelectSingleNode("soap:Envelope/soap:Body/stupid_xmlns:GetAvailability/stupid_xmlns:request/stupid_xmlns:RequestDetails/stupid_xmlns:GoldAddressKey", manager);
GoldAddressKeyNode.InnerXml = GoldAddressKey;
//Send Request To API
string _url = "https://b2b.api.talktalkgroup.com/api/v2/partners/AvailabilityCheckers/NPAC/v45";
string _action = "http://webservices.talktalkplc.com/NetworkProductAvailabilityCheckerService/NetworkProductAvailabilityCheckerService/GetAvailability";
string xml = doc.InnerXml;
var soapResult = WebService.ApiRequest(_url, _action, xml);
XmlDocument xmlToFormat = new XmlDocument();
xmlToFormat.LoadXml(soapResult);
string Outerxml = xmlToFormat.FirstChild.FirstChild.FirstChild.FirstChild.ChildNodes[2].InnerXml;
//Remove all namespaces
var xmlToBeStripped = XElement.Parse(Outerxml);
string finalXml = XmlFormatter.stripNS(xmlToBeStripped).ToString();
EADAvailabilityDetails result;
// Deserialises xlm into an object
XmlSerializer serializer = new XmlSerializer(typeof(EADAvailabilityDetails));
using (TextReader reader = new StringReader(finalXml))
{
result = (EADAvailabilityDetails)serializer.Deserialize(reader);
}
return result;
}

Deserialize XML values to objects

I'm trying to use XDocument to read in XML and deserialize it to objects.
I want to take the following XML:
<r25:spaces xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xl="http://www.w3.org/1999/xlink" xmlns:r25="http://www.collegenet.com/r25" pubdate="2019-07-15T14:51:16-07:00" engine="accl">
<r25:space crc="00000022" status="est" xl:href="space.xml?space_id=200">
<r25:space_id>200</r25:space_id>
<r25:space_name>LRN 0001</r25:space_name>
<r25:formal_name>Learning Commons -Test Scheduling Room</r25:formal_name>
<r25:partition_id xl:href="rmpart.xml?partition_id=2">2</r25:partition_id>
<r25:last_mod_dt>2019-07-11T08:01:00-07:00</r25:last_mod_dt>
</r25:space>
</r25:spaces>
and deserialize it to a List of spaces (where Space has the following definition):
public class Space
{
public long space_id { get; set; }
public string space_name { get; set; }
public string formal_name { get; set; }
public long partition_id { get ; set; }
public DateTime last_mod_dt { get; set; }
}
I've only gotten so far as to get the XElement. It dies on the serializer
var doc = XDocument.Parse(result.Content);
XNamespace ns = "http://www.collegenet.com/r25";
XElement el = doc.Element(ns + "spaces");
foreach (var space in el.Elements())
{
var serializer = new XmlSerializer(typeof(Space));
var s = (Space)serializer.Deserialize(space.CreateReader());
}
You can simply use LINQ to XML here. e.g.
using System;
using System.Linq;
using System.Xml.Linq;
namespace ConsoleApp22
{
public class Space
{
public long space_id { get; set; }
public string space_name { get; set; }
public string formal_name { get; set; }
public long partition_id { get; set; }
public DateTime last_mod { get; set; }
}
class Program
{
static void Main(string[] args)
{
var xml = #"
<r25:spaces xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xl=""http://www.w3.org/1999/xlink"" xmlns:r25=""http://www.collegenet.com/r25"" pubdate=""2019-07-15T14:51:16-07:00"" engine=""accl"">
<r25:space crc=""00000022"" status=""est"" xl:href=""space.xml?space_id=200"">
<r25:space_id>200</r25:space_id>
<r25:space_name>LRN 0001</r25:space_name>
<r25:formal_name>Learning Commons -Test Scheduling Room</r25:formal_name>
<r25:partition_id xl:href=""rmpart.xml?partition_id=2"">2</r25:partition_id>
<r25:last_mod_dt>2019-07-11T08:01:00-07:00</r25:last_mod_dt>
</r25:space>
</r25:spaces>
";
var doc = XDocument.Parse(xml);
XNamespace ns = "http://www.collegenet.com/r25";
var q = from e in doc.Element(ns + "spaces").Elements()
select new Space
{
space_id = (int)e.Element(ns + "space_id"),
space_name = (string)e.Element(ns + "space_name"),
formal_name = (string)e.Element(ns + "formal_name"),
partition_id = (long)e.Element(ns + "partition_id"),
last_mod = (DateTime)e.Element(ns + "last_mod_dt")
};
var space = q.First();
}
}
}
You can add the XmlRoot to your class to declare the namespace for that element:
[XmlRoot("space", Namespace = "http://www.collegenet.com/r25")]
public class Space
{
public long space_id { get; set; }
public string space_name { get; set; }
public string formal_name { get; set; }
public long partition_id { get; set; }
public DateTime last_mod { get; set; }
}
The deserializer will now correctly read the XML as an object.
Use the the XSD tool to generate the class and then use XmlSerializer to populate the class. Like this.
MyClass myClass;
using (var stream = new FileStream("myClass.xml", FileMode.Open))
{
var serializer = new XmlSerializer(typeof(MyClass));
myClass = serializer.Deserialize(stream);
}
I found a website that will take XML and create the proper deserialization classes. Xml2CSharp, which created the following classes that allowed the deserialization to work:
[XmlRoot(ElementName="partition_id", Namespace="http://www.collegenet.com/r25")]
public class Partition_id {
[XmlAttribute(AttributeName="href", Namespace="http://www.w3.org/1999/xlink")]
public string Href { get; set; }
[XmlText]
public string Text { get; set; }
}
[XmlRoot(ElementName="space", Namespace="http://www.collegenet.com/r25")]
public class Space {
[XmlElement(ElementName="space_id", Namespace="http://www.collegenet.com/r25")]
public string Space_id { get; set; }
[XmlElement(ElementName="space_name", Namespace="http://www.collegenet.com/r25")]
public string Space_name { get; set; }
[XmlElement(ElementName="formal_name", Namespace="http://www.collegenet.com/r25")]
public string Formal_name { get; set; }
[XmlElement(ElementName="partition_id", Namespace="http://www.collegenet.com/r25")]
public Partition_id Partition_id { get; set; }
[XmlElement(ElementName="last_mod_dt", Namespace="http://www.collegenet.com/r25")]
public string Last_mod_dt { get; set; }
[XmlAttribute(AttributeName="crc")]
public string Crc { get; set; }
[XmlAttribute(AttributeName="status")]
public string Status { get; set; }
[XmlAttribute(AttributeName="href", Namespace="http://www.w3.org/1999/xlink")]
public string Href { get; set; }
}
[XmlRoot(ElementName="spaces", Namespace="http://www.collegenet.com/r25")]
public class Spaces {
[XmlElement(ElementName="space", Namespace="http://www.collegenet.com/r25")]
public Space Space { get; set; }
[XmlAttribute(AttributeName="xsi", Namespace="http://www.w3.org/2000/xmlns/")]
public string Xsi { get; set; }
[XmlAttribute(AttributeName="xl", Namespace="http://www.w3.org/2000/xmlns/")]
public string Xl { get; set; }
[XmlAttribute(AttributeName="r25", Namespace="http://www.w3.org/2000/xmlns/")]
public string R25 { get; set; }
[XmlAttribute(AttributeName="pubdate")]
public string Pubdate { get; set; }
[XmlAttribute(AttributeName="engine")]
public string Engine { get; set; }
}

Deserialize XML with list of elements where some are xsi:nil=“true”

When I deserialize the XML below, from a third-party, my objects are always null.
XML
<?xml version="1.0"?>
<OrderImport xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Reply i:nil="true">
</Reply>
<ReplyStatus i:nil="true">
<DebugInfo>
</DebugInfo>
<PerformanceLogInfo>
</PerformanceLogInfo>
</ReplyStatus>
<Reply>
<OrderNumber>4063286</OrderNumber>
</Reply>
<ReplyStatus>
<Result>0</Result>
<Message>
</Message>
</ReplyStatus>
</OrderImport>
C# Class
[XmlRoot(ElementName = "OrderImport")]
public class OrderImport
{
[XmlElement(ElementName = "Reply")]
public List<Reply> Reply { get; set; }
[XmlElement(ElementName = "ReplyStatus")]
public List<ReplyStatus> ReplyStatus { get; set; }
[XmlAttribute(AttributeName = "i", Namespace = "http://www.w3.org/2000/xmlns/")]
public string I { get; set; }
}
[XmlRoot(ElementName= "Reply")]
public class Reply
{
[XmlAttribute(AttributeName = "nil", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public string Nil { get; set; }
[XmlElement(ElementName = "OrderNumber")]
public string OrderNumber { get; set; }
}
[XmlRoot(ElementName = "ReplyStatus")]
public class ReplyStatus
{
[XmlElement(ElementName = "DebugInfo")]
public string DebugInfo { get; set; }
[XmlElement(ElementName = "PerformanceLogInfo")]
public string PerformanceLogInfo { get; set; }
[XmlAttribute(AttributeName = "nil", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public string Nil { get; set; }
[XmlElement(ElementName = "Result")]
public string Result { get; set; }
[XmlElement(ElementName = "Message")]
public string Message { get; set; }
}
I believe the problem has to do with the first occurrence of the objects Reply and ReplyStatus being null.
I'm trying to deserialize like so
httpResponseMessage.Content.ReadAsAsync<OrderImport>().Result;
However, I've found that if I deserialize like this it works just fine
stringres = httpResponseMessage.Content.ReadAsStringAsync().Result;
using (var stringreader = new StringReader(stringres))
{
var result = (OrderImport)xmlSerializer.Deserialize(stringreader);
}
