C# parse XML File

C# parse XML File - c#

I've a problem to parse my XML File (RSS Feed) in C#.
I just want to read out the "entry" entries (the root parent - "feed" - is not relevant).
All "entry" entries are almost even, except the part "state". Some entries doesn't have that entry.
So i just want to read out the following:
"entry" nodes:
updated
expires
title
summary
state (if exists)
Any suggestions?
Thank you very much.

My current C# code:
public void ParseXML(XmlDocument xmlFile)
{
ArrayList updated = new ArrayList();
ArrayList expires = new ArrayList();
ArrayList title = new ArrayList();
ArrayList summary = new ArrayList();
ArrayList state = new ArrayList();
ObservableCollection<TrafficInformation> trafInfo = new ObservableCollection<TrafficInformation>();
myCollection = trafInfo;
XmlNodeReader reader = new XmlNodeReader(xmlFile);
StringBuilder output = new StringBuilder();
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element:
if(reader.Name == "updated")
{
updated.Add(reader.ReadString());
}
if (reader.Name == "expires")
{
expires.Add(reader.ReadString());
}
if (reader.Name == "title")
{
title.Add(reader.ReadString());
}
if (reader.Name == "summary")
{
summary.Add(reader.ReadString());
}
if (reader.Name == "state")
{
state.Add(reader.ReadString());
}
break;
}
}
}
In that case, I don't have a relationship between the data (if state doesn't exists).

I believe the easiest way to parse the XML directly is using LINQ-TO-XML. You can find more info here.

You could use XPath expression for that. Below is complete example on console-appliactaion - as you use xlmns namespace, it requries a little modification of ParseXML method.
using System;
using System.Xml;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load("XMLFile1.xml");
XmlNamespaceManager xmlnm = new XmlNamespaceManager(xmlDocument.NameTable);
xmlnm.AddNamespace("ns", "http://www.w3.org/2005/Atom");
ParseXML(xmlDocument, xmlnm);
Console.WriteLine("\n---XML parsed---");
Console.ReadKey();
}
public static void ParseXML(XmlDocument xmlFile, XmlNamespaceManager xmlnm)
{
XmlNodeList nodes = xmlFile.SelectNodes("//ns:updated | //ns:expires | //ns:title | //ns:summary | //ns:state", xmlnm);
foreach (XmlNode node in nodes)
{
Console.WriteLine(node.Name + " = " + node.InnerXml);
}
}
}
}
// in XPath expression means, you want to select all nodes with specific name, no matter where they are.
If you want to search only <entry></entry> elements, you can use following:
"//ns:entry/ns:updated | //ns:entry/ns:expires | //ns:entry/ns:title | //ns:entry/ns:summary | //ns:entry/ns:state"

How do I replace multiple <br/> tags with a specific element in a new line?

I have a XML file that contains multiple <p> tags in it. Some of the <p> tags contain <br/> in it. So, I am supposed to create a new XElement for each <br/> in the tag. I have tried to achieve by reading each line using foreach and replacing each <br/> with </p> + Environment.NewLine + <p>.
It works but if <p> contains tags like <b> or <i>, then < and > become < and > respectively. Which is why, I want a linq approach or a foreach approach, so that I am able to do the changes while in XML format.
Plase help.

What I tried:
List<XElement> brs = xdoc.Descendants("br").ToList();
for (int i = brs.Count - 1; i >= 0; i--)
{
brs[i].ReplaceWith(new XElement("br", new XElement("p", new object[] {brs[i].Attributes(), brs[i].Nodes()})));
}
I got this code from StackOverflow itslef in one of my older questions.
What I get:

</break>

</repub>

This may not be the best answer but it will do most of what you want:
List<XElement> p = xdoc.Descendants("p").ToList();
for (int i = p.Count - 1; i >= 0; i--)
{
var newP = new XElement("p");
newP.ReplaceAttributes(p[i].Attributes());
foreach (var node in p.Nodes())
{
if (node.NodeType == System.Xml.XmlNodeType.Element && ((XElement)node).Name == "br")
{
p[i].AddBeforeSelf(newP);
newP = new XElement("p");
newP.ReplaceAttributes(p[i].Attributes());
}
else
{
newP.Add(node);
}
}
p[i].AddBeforeSelf(newP);
p[i].Remove();
}

I wanted to try a different approach to see if it would work … by leveraging Regular Expressions. It isn't as elegant as using XML document, but it was fun to try out.
void Main()
{
string info = #"<?xml version=""1.0"" encoding=""UTF-8""?>
<!DOCTYPE repub SYSTEM ""C:\repub\Repub_V1.dtd"">
<?xml-stylesheet href=""C:\repub\repub.xsl"" type=""text/xsl""?>
<repub>
<head>
<title>xxx</title>
</head>
<body>
<sec>
<title>First Title</title>
<break name=""1-1""/>
<pps>This is Sparta</pps>
<h1><page num=""1""/>First Heading</h1>
<bl>This is another text</bl>
<fig><img src=""images/img_1-1.jpg"" alt=""""/><fc>This is a caption</fc></fig>
<p>This is a sentence<br/> that will be broken down <br/>into separate paragraph tags.</p>
</break>
</sec>
</body>
</repub>";
string result = null;
try
{
Regex regexObj = new Regex("<p>(.*?)</p>", RegexOptions.IgnoreCase | RegexOptions.Multiline);
result = regexObj.Replace(info, new MatchEvaluator(ConvertBR));
result.Dump();
}
catch (ArgumentException ex)
{
// Syntax error in the regular expression
}
}
public String ConvertBR(Match m)
{
return m.Value.Replace("<br/>","</p><p>");
}

Why does this XPath expression work for one node but not the other?

I have a function that retrieves the .InnerText for an attribute in an XML node:
string getPropertyFromNode_string(XmlNode node, string propertyName)
{
try
{
string selectString = "./empty:content/m:properties/d:";
return node.SelectSingleNode(selectString + propertyName, Utils.nmREST).InnerText;
}
catch (Exception exception)
{
Console.WriteLine(exception.Message);
throw exception;
}
}
nmREST is defined in the constructor of a static Utils class as follows:
public static XmlNamespaceManager nmREST = new XmlNamespaceManager(new NameTable());
static Utils()
{
nmREST.AddNamespace("d", "http://schemas.microsoft.com/ado/2007/08/dataservices");
nmREST.AddNamespace("m", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
nmREST.AddNamespace("empty", "http://www.w3.org/2005/Atom");
nmREST.AddNamespace("z", "#RowsetSchema");
}
I test the function on this XmlNode:
<entry m:etag=""81"" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://www.w3.org/2005/Atom">

using this function call:
getPropertyFromNode_string(thisNode,"ID")
and the value 1213 is successfully retrieved.
However, when I test it on the following XmlNode:

using the function call:
getPropertyFromNode_string(thisNode,"FacilityNumber")
then the SelectSingleNode() call throws an exception with the message:
Object reference not set to an instance of an object.
I guess this means that the XPath expression isn't successfully locating the <d:FacilityNumber> element, so there's no object to get InnerText from. Why isn't the element being found? What's different about the second node's XML structure, and what XPath expression should I be using instead?

As per Laurent Lequenne's comment on the OP, including the full nesting sequence of child nodes in the XPath expression successfully retrieves the desired child node, as follows:
./empty:link/m:inline/empty:entry/empty:content/m:properties/d:

How to read the XML response from SharePoint REST api call

I am getting XML response for REST call which includes multiple subnodes for each entry. Basically any Lookup field or User field results in a subnode.
Can anybody help me to understand how to read these subnodes? As the element name is Id or Email which is repetitive. Sorry for the very long XML but this is a result of fetching only 2 items.

The code i am using is but is not giving the expected results :
XmlDocument listXml = new XmlDocument();
XmlNamespaceManager xmlnspm = new XmlNamespaceManager(new NameTable());
xmlnspm.AddNamespace("atom", "http://www.w3.org/2005/Atom");
xmlnspm.AddNamespace("d", "http://schemas.microsoft.com/ado/2007/08/dataservices");
xmlnspm.AddNamespace("m", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
listXml.LoadXml(response);
var prop = listXml.SelectNodes("//atom:entry/atom:content/m:properties", xmlnspm);
List<string> sdsd = new List<string>();
foreach (XmlNode ndlist in prop)
{
sdsd.Add(ndlist.SelectSingleNode("d:Id", xmlnspm).InnerXml +
ndlist.SelectSingleNode("d:EMail", xmlnspm).InnerXml +
ndlist.SelectSingleNode("d:Status", xmlnspm).InnerXml+
ndlist.SelectSingleNode("d:History", xmlnspm).InnerXml);
}
The result i am looking for is :
For each entry, read the
If Name then Name(Id and Email)
If Segment then Segment(Title and Id)
If BU then BU(Title and Id)
If Author0 then Author0(Id and Email)
...likewise for all subnodes
and for all main nodes i need the value
Id
Title
End_x0020_Use
Approval_x0020_Type
Is there any way to Serialize this data in a more readable format or i'l have to loop each and every node?
Please suggest the best option as i don't have much experience in XML data.

Use xml linq
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication4
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static List<XElement> nodes;
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement feed = doc.Root;
XNamespace ns = feed.GetDefaultNamespace();
foreach (XElement entry in feed.Elements(ns + "entry"))
{
Entry newEntry = new Entry();
Entry.entries.Add(newEntry);
newEntry.title = (string)entry.Element(ns + "title");
newEntry.end_x0020_Use = (string)entry.Descendants().Where(x => x.Name.LocalName == "End_x0020_Use").FirstOrDefault();
newEntry.approval_x0020_Type = (string)entry.Descendants().Where(x => x.Name.LocalName == "Approval_x0020_Type").FirstOrDefault();
newEntry.links = entry.Elements(ns + "link").Select(x => x.Descendants().Where(y => y.Name.LocalName == "entry").Select(y => new Link() {
name = (string)y.Descendants().Where(z => z.Name.LocalName == "name").FirstOrDefault(),
id = (string)y.Descendants().Where(z => z.Name.LocalName == "id").FirstOrDefault(),
email = (string)y.Descendants().Where(z => z.Name.LocalName == "EMail").FirstOrDefault(),
title = (string)x.Attributes().Where(z => z.Name.LocalName == "title").FirstOrDefault()
}).FirstOrDefault()
).ToList();
}
}
}
public class Entry
{
public static List<Entry> entries = new List<Entry>();
public string title { get; set;}
public string end_x0020_Use { get; set; }
public string approval_x0020_Type { get; set; }
public List<Link> links { get; set; }
}
public class Link
{
public string name { get; set; }
public string id { get; set; }
public string title { get; set; }
public string email { get; set; }
}
}

I would advise you to use $filter in your REST API call so that you would get a JSON result which is pretty much easy to work with. The XML retrieval may fail sometimes.

I have a piece of code where I want to simply console output the values of each Urls.
var reader = new StreamReader(#"C:/Users/Administrator/Downloads/direct.xml")
var xmlDoc = XDocument.Load(reader);
XNamespace atom = "http://www.w3.org/2005/Atom";
XNamespace metadata = "http://schemas.giooglt.com/ado/2007/08/dataservices/metadata";
XNamespace dataservices = "http://schemas.google.com/ado/2007/08/dataservices";
var result = xmlDoc.Root.Elements(atom + "entry")
.Select(e => new {
Title = e.Element(atom + "title").Value,
Id = e.Element(atom + "id").Value,
Urls = e.Elements(atom + "link")
.Where(l => l.Element(metadata + "inline") != null)
.SelectMany(l => l.Element(metadata + "inline")
.Element(atom + "feed")
.Elements(atom + "entry")
.Select(e1 => e1.Element(atom + "content")
.Element(metadata + "properties")
.Element(dataservices + "Url").Elements.Select(url => url.Value)))
});
foreach (var item in result)
{
Debug.WriteLine("{0}, {1}", item.Title, item.Id);
var urls = System.String.Join(",",item.Urls);
Debug.WriteLine(urls);
}
Here Urls are of type 'Ienumerable Urls'. How to get the values of every element in Urls.

Ah, I see. You want a comma-separated list of the URLs. As you pointed out, your Urls property is an IEnumerable of strings, so you need to actually iterate over those strings to build the final string you're looking for.
Try this:
var result = xmlDoc.Root.Elements(atom + "entry")
.Select(e => new {
Title = e.Element(atom + "title").Value,
Id = e.Element(atom + "id").Value,
Urls = e.Elements(atom + "link")
.Where(l => l.Element(metadata + "inline") != null)
.SelectMany(l => l.Element(metadata + "inline")
.Element(atom + "feed")
.Elements(atom + "entry")
.Select(e1 => e1.Element(atom + "content")
.Element(metadata + "properties")
.Element(dataservices + "Url").Value))
});
foreach(var r in result)
{
Debug.WriteLine("{0},{1},{2}", r.Title, r.Id, String.Join(",", r.Urls));
}
Just curious: since you're apparently parsing an ATOM feed, have you looked into packages that will do this for you? https://www.nuget.org/packages?q=atom

how to parse XML to get the data in c#?

I have an xml file and I want to the write the information on to the csv file.
I am trying to parse the xml to get the fields and the data and write onto a csv file. So far I have been able to parse the data to get the information in relation to
'title' and 'id' under node 'entry' but I am trying to parse the data under node '', 'id' information.

The entries will be different but as one sees, I want to extract the information and write it onto a CSV file as -
Title,Id,PinpointId
//de:entry/de:title,//de:entry/de:title,//de:entry/de:link/m:inline/de:feed/de:id
for each and every entry.
The piece of code being used to get the information is :
// Alternate Method for getting the Fields from the XML file
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load("C:/Users/Administrator/Downloads/direct.xml");
XmlNamespaceManager xmlnm = new XmlNamespaceManager(xmlDocument.NameTable);
xmlnm.AddNamespace("de","http://www.w3.org/2005/Atom");
xmlnm.AddNamespace("m", "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata");
xmlnm.AddNamespace("d", "http://schemas.microsoft.com/ado/2007/08/dataservices");
ParseXML(xmlDocument, xmlnm);
Debug.WriteLine("\n---XML parsed---");
}
public static void ParseXML(XmlDocument xmlFile, XmlNamespaceManager xmlnm)
{
String path = "C:/Users/Administrator/Downloads/data.csv";
var w = new StreamWriter(path);
XmlNodeList nodes = xmlFile.SelectNodes("//de:entry", xmlnm);
foreach (XmlNode node in nodes)
{
string titl = node["title"].InnerText;
string ide = node["id"].InnerText;
//string cty = node["link/m:inline/de:feed/de:id"].InnerText;
Debug.WriteLine("Data :" + titl+"ID :"+ide);
}
}
The output of the program is -
Data :MIG & CoID :http://pinpoint.microsoft.com/en-US/syndicate/Partners('4295719419')
I am trying to parse the data like.
string cty = node["link/m:inline/de:feed/de:id"].InnerText;
But the error generated.
"Object reference not set to an instance of an object."
The xml has got multiple entries and in similar format. New to C# how to get the information and write it on to the CSV file.Please help me.

First, your xml is not well formed. It will need to be corrected. Second, I am unsure exactly what node you are attempting to return with the query "link/m:inline/de:feed/de:id"
With that said, your node["link/m:inline/de:feed/de:id"] isn't valid, so it's not getting set to the XmlNode object you are expecting. That's because an XmlNode item expects the name of a node, not an xpath query. Use SelectSingleNode if you want to pass an xpath query. Something like this:
foreach (XmlNode node in nodes)
{
string titl = node["title"].InnerText;
string ide = node["id"].InnerText;
string cty;
var ctyNode = node.SelectSingleNode("link/m:inline/de:feed/de:id");
if (ctyNode != null)
{
cty = ctyNode.InnerText
}
Debug.WriteLine("Data :" + titl+"ID :"+ide);
}

C# (C-Sharp) is a programming language developed by Microsoft that runs on the .NET Framework.

C# parse XML File - c#

I believe the easiest way to parse the XML directly is using LINQ-TO-XML. You can find more info here.
