How to read XML in C#?

Question

I have an XML file which looks like this

<ss:demo>
<ss:Name>
    <ss:FirstName>First</ss:FirstName>
    <ss:SecondName>Second</ss:SecondName>
</ss:Name>
<ss:country code="IN">India</ss:country>
</ss:demo>

How can I read this using C#. Please help me in this. which will be easiest way for reading it? I tried to read it into a DataSet but its showing some error.

What error is it showing, and what do you want to do with the XML after you have read it in? — Eric J.

I can see two XML errors: no namespace declaration and IN isn't in quotes in the code attribute. My answer expects the second to be fixed and works regardless of the first. — yamen

There are several strategies to read an XML document, or parts thereof, using C#. If you are more specific about what you want to do with the XML document, the community can provide you with more specific guidance.

Here are some top choices:

Linq to XML

XDocument (part of the Linq to XML framework)

http://msdn.microsoft.com/en-us/library/bb387063.aspx

XmlDocument

XPath

How about just LINQ to XML?

Given this:

var xml = "<ss:demo>\r\n<ss:Name>\r\n    <ss:FirstName>First</ss:FirstName>\r\n    <ss:SecondName>" +
"Second</ss:SecondName>\r\n</ss:Name>\r\n<ss:country code=\"IN\">India</ss:country>\r\n</ss" +
":demo>";

(Note I had to wrap IN in quotes as such "IN")

Declare some namespaces and read it in:

var mngr = new XmlNamespaceManager( new NameTable() );
mngr.AddNamespace( "ss", "urn:ignore" ); // or proper URL
var parserContext = new XmlParserContext(null, mngr, null, XmlSpace.None, null);

If reading from a string as above:

var txtReader = new XmlTextReader( xml, XmlNodeType.Element, parserContext );

If reading from a file instead:

var txtReader = new XmlTextReader( new FileStream(filename, FileMode.Open), XmlNodeType.Element, parserContext );

Then load:

var ele = XElement.Load( txtReader );

ele contains everything you need.

You meant XDocument.Load in this case, right? (downvote was not from me)

Yes it's a file, but to show an example I used a string. I've updated to include what it would be like with a file.
