How to traverse through all the nodes in an XML document

[Murtaza Tinwala]

Hello friends,

I have a XML document and I want to modify some of its nodes.
What I need to do is traverse through all the nodes and test the name
of each. If the node is to be modified, I would output the modified
code or I would output the same code.

Is there any way I can get all nodes from the root node? Or, let
me put this question in another way. Is there an easy way to modify
XML document. Say, I want to make minor changes to an XML document
and donot want to touch the rest of the document? How can I do this?

You could do your changes using XSLT and use XPath to get the nodes you
want to edit. An expression like "//*" gets all the nodes in the XML
document. For a quick introduction to XSLT and XPath have a look at
