How to read the XML response from SharePoint REST api call

How to read the XML response from SharePoint REST api call - c#

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.

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:

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

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);
}

It sort of works with the following, but my brain gets fuzzy trying to get all the attributes in the first "group by" and how to add the other groupings that inevitably follow.
XDocument xDoc = new XDocument(
new XDeclaration("1.0", "utf-8", "yes"),
new XComment("XML Source Data for Dial Flash"),
new XElement("workflows",
from sec in xVar.Elements("vSection")
//group sec by (string)sec.Attribute("sectionTitle").Value,
group sec by (string)sec.Attribute("sectionTitle").Value into gsec
select new XElement("section",
new XAttribute("sectionTitle", gsec.Key)
)
)
);
Is there a better way to do this? Bonus if the dates can be converted to MM/dd/yyyy in the process...

Try this:
var xVar = XElement.Load("XMLFile1.xml");
var query = xVar.Elements("vSection").
GroupBy(grp => (string)grp.Attribute("sectionTitle")).
Select(grp => new XElement("section", grp.First().Attributes(),
grp.Select(vsec => new XElement("category",
vsec.Element("vCategory").Attributes(),
vsec.Element("vCategory").Elements()))
)
)

XML extracting attributes using XMLDocument

i am trying to parse an xml element using XMLDocument (DItem >> Title)
below is my code but somehow i am not getting hold of it.... any help?
XmlDocument xmldoc = new XmlDocument();
XmlNamespaceManager xmlns = new XmlNamespaceManager(xdoc.NameTable);
xmlns.AddNamespace("DItems", "http://namespace.xsd");
xmldoc.Load(url);
var title = xmldoc.SelectNodes("content", xmlns);
foreach (XmlNode node in title)
{
string title = node.Attributes["Title"].Value;
//this.ddlTitle.Items.Add(new ListItem(title));
}
here is my XML:
<?xml version='1.0'?>
<root xmlns="http://www.w3.org/2005/Atom">
<title type="text">title</title>
<entry>
<content type="application/xml">
<Items xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.namespace.xsd">
<CatalogSource Acronym="ABC" OrganizationName="organization name" />
<Item Id="28466" CatalogUrl="url">
<DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title1">
<content:Source Acronym="ABC" OrganizationName="ABC" />
</DItem>
</Item>
</Items>
</content>
</entry>
<entry>
<content type="application/xml">
<Items xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.namespace.xsd">
<CatalogSource Acronym="ABC" OrganizationName="organization name" />
<Item Id="28466" CatalogUrl="url">
<DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title2">
<content:Source Acronym="ABC" OrganizationName="ABC" />
</DItem>
</Item>
</Items>
</content>
</entry>
<entry>
<content type="application/xml">
<Items xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.namespace.xsd">
<CatalogSource Acronym="ABC" OrganizationName="organization name" />
<Item Id="28466" CatalogUrl="url">
<DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title3">
<content:Source Acronym="ABC" OrganizationName="ABC" />
</DItem>
</Item>
</Items>
</content>
</entry>
</root>

var xmldoc = new XmlDocument();
var xmlns = new XmlNamespaceManager(xmldoc.NameTable);
xmlns.AddNamespace("DItems", "http://www.namespace.xsd");
xmldoc.Load(url);
var titleNodes = xmldoc.SelectNodes("//DItems:DItem/#Title", xmlns);
var result = titleNodes.Cast<XmlAttribute>().Select(a => a.Value).ToList();
Output (list of objects):
my title1
my title2
my title3
