This is my short overview of different XML parsing methods you can use:

  1. Use System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.

  2. Use the class System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.

  3. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.

Thanks..can u please explain with an example.
I don't see why you need more explanation. No, first of all, did you already try any of these API? No? Then why wasting more time?

Try it out, and ask a question if you face any problems. Isn't it fair? After all, you are supposed to do you work be yourself, as you are a software developer.
OK, if you are a fresher, this is just yet another reason to start diffing into it. And then you will see how. Documentation is rich, with code samples... When I advise it, I know what I say. This is the most effective thing you can do about it. Any additional instructions won't help more, really.

Solution 3

string str = "your xml string";
XDocument document = XDocument.Parse(str);
var books = document.Descendants("book");
foreach (XElement item in books)
    var idElement = item.Element("id");
    if (idElement.HasAttributes)
        XAttribute attr = idElement.Attribute("isPrimaryKey");
        string attrValue = attr.Value;

<?xml version="1.0" encoding="utf-8"?>
	<id isPrimaryKey="true">3785</id>
        <name>CLR via C#</name>
