Do I understand you correctly that you want to dissect XML data using Wireshark? I think shoehorning an XML parser into the Wireshark dissection engine would be a much bigger effort and development headache than it's worth in that case. Why is an actual XML parser not suitable for your application? On the other hand, if you intend to analyze XML data within another protocol, that might be different. Can you clarify your intent?

If the xml is transfered via a protocol using mime type such as HTTP in "Application=" you may only have to add the mime type to the list in packet-xml.c. If you have a tvb with xml data you can let the xml dissector dissectit by callng it with the tvb. packet-diameter_3gpp.c calls the xml dissector I think.

Get an XML viewer application and read the file. Wireshark's XML dissector won't do much more than show you the individual XML elements, as you've already done.

Not sure to understand what you expect here. Your XML description already contains the field name, the length and the raw value. You can hardly get more. If you want an interpretation of the raw fields, Wireshark cannot help you. Those fields look like some RRC 3G info but you would need the raw data (byte stream) and the corresponding protocol dissector in Wireshark, not a pre-decoded XML data.

my current requirement I need to write a code for dissecting the xml data if any approach briefly explain me and provide any screen shots or any links for how to write a code for dissecting the xml..

I'm really sorry but I have no idea of what you mean: what does dissecting xml means for you? If it is just to display the xml data in a tree view, use an XML viewer as Guy suggested.
