in thread XML access the REPEATING NODE VALUES

You are indeed correct it has been factored-out. Thank you for the clarification. Nevertheless, XSLT is there and well-supported to do exactly jobs like this, with or without(!) Perl being involved. Logic that attempts to do this "by hand" becomes extremely specific to the XML data structure that was originally parsed when it was originally written, and can be extremely difficult to accurately update when the XML definition changes. Fully-leveraging XML technologies via these standard binaries eliminates great code complexity and improves maintainability.

    This sentence could just as well apply to XSLT. Properly written Perl code will be easy to adapt to changes in the XML.

    I've written XSLT, and I found its syntax somewhat cumbersome.

    Plus, Perl is much more powerful (regexes, the ability to access other data sources like databases, JSON, and so on). Sorry, I currently don't see the strength of your argument for XSLT. But perhaps you could write an XSLT solution that demonstrates its advantages.

    Yeah, but only 17 years ago so you were definitely on point, geologically speaking. And it was the other way around. XML::LibXML was part of the XML::LibXSLT dist but what's a bucket of chum between friends!

    XSLT is there and well-supported to do exactly jobs like this, with or without(!) Perl being involved.

    Can't wait to see you post an example that solves an OP's question with either recommended approach! Heat death of Universe being the scientifically predicted time scale in that case.
