In other words, this may be a job for XPath:
[....] The primary purpose of XPath is to address parts of an XML document. In support of this primary purpose, it also provides basic facilities for manipulation of strings, numbers and booleans. XPath uses a compact, non-XML syntax to facilitate use of XPath within URIs and XML attribute values. XPath operates on the abstract, logical structure of an XML document, rather than its surface syntax. XPath gets its name from its use of a path notation as in URLs for navigating through the hierarchical structure of an XML document.

The main Perl module for this is XML::XPath:
This module aims to comply exactly to the XPath specification at http://www.w3.org/TR/xpath and yet allow extensions to be added in the form of functions. Modules such as XSLT and XPointer may need to do this as they support functionality beyond XPath.

There is a family of related modules as well:

Depending on what you want to do with the XML data, XSLT may also help:
[A] language for transforming XML documents into other XML documents.
<http://www.w3.org/TR/xslt>
It, too, has a Perl module interface:

I suspect that XPath and XSLT may be the tools you're looking for ...
