Do you know how to read an XML file into "objects" (create a XmlDocument ... or DOM ... from the XML) ? That's what you will need to do to change a specific property or state; and then, you'll need to save the changed DOM back to the file to update the file.I suggest you start by doing some...

If your issue is just to get the fragment. One way of doing this is:var reader = XmlReader.Create(YOUR_SERIALIZED_FILE_NAME);reader.Read();reader.ReadToFollowing(NODE_NAME);Then use either reader.ReadOuterXml() or reader.ReadInnerXml() as per ur requirement.Hope this would help.

You will need to create a Serializable class that represents this XML format and then use XMLSerializer class and its methods to get the object.You can use XSD.exe to create class that will represent this XML.

What you want doesn't seem to be too standard, XML explicitly disallows numbers (and some other things) as the first character of an element name:NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | ...
