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.
    See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^].
  2.  
  3. Use the class System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
    See http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^].
  4.  
  5. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
    See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^], http://msdn.microsoft.com/en-us/library/bb387063.aspx[^].

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.

            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;
                    Console.WriteLine(attrValue);
                }
            }
            Console.Read();
 
XML:
<?xml version="1.0" encoding="utf-8"?>
<books>
<book>
	<id isPrimaryKey="true">3785</id>
        <name>CLR via C#</name>
</book>
</books>
