There are a number of possible transformation tools that are part of XPP that you could use.

I suggest you read Chapter 3 of the latest version of the XPP Transforming Data manual.

Here's a part of the beginning of that chapter (text in brackets added here by me):

With XyChange, you can transform text to a format appropriate for your needs. You can also choose the tool appropriate for your task. XyChange can be used to launch Perl or OmniMark scripts, or XSLT style sheets. Each transformation technology has its strengths and weaknesses:

• XyChange [i.e. using classic XPP tt specs] offers fast pattern matching.
• Perl offers strong string processing capability, ways to work with XML structure, and strong UTF-8 support.
• OmniMark offers the ability to program using the structure of an SGML or XML instance.
• XSLT [XSLT 1 or XSLT 2] gives you a standard way to work with XML, transforming it as required.
