Does anyone have suggestions for an active and easy to use XML building =
& parsing module?

Hi Doug
Any code to write XML ends up looking very similar to the resulting XML
itself, although XML::Writer will make sure your syntax is correct for
you and avoid a lot of obvious errors.
As for parsing, it largely depends on what you want to do once you have
parsed tha XML. But XML::LibXML is a good all-rounder (although with
awkward documentation). XML::Twig and XML::TreeBuilder are also worth a
look.
HTH,
Rob

For a simple XML parsing I have used the module XML::Simple which just run well.

Recently having done some work with various XML libraries in perl I have to
recommend: XML::LibXML the documentation is well how to put it not
fantastic... but once you get passed that you are looking at probably the
fastest and most powerful library for XML parsing available in perl.
It really depends on what you are looking to do though, if you are aiming
for just a simple thing with only a few messages then don't worry
about XML::LibXML
and go for XML::Simple which is more then enough in most simple cases ;-)
I found that both Twig and Treebuilder are great if you are looking at
modifying the XML (add extra nodes, alter existing nodes) but since they
build a full tree structure for the XML file you are working with depending
on the size and complexity of the file this could cause serious memory
bloat, and even out of memory errors.
Personally I think that if you can stomach it getting past the somewhat
difficult XML::LibXML documentation it will provide you the best and fastest
way of working with XML files, but I have to be honest it took me several
years before I found a project where I needed the speed and power of LibXML.
On the other hand once learned... if you have the time to do so have a go at
it you will enjoy working with it once you know how to.
Regards,
Rob

Except that it's not so simple to set it up to give you consistent
data structure with things like optional tag attributes and repeated
tags. See http://www.perlmonks.org/?node_id=697036

XML::Twig (as the name suggests) is not supposed to build a full tree
structure, but rather lets you work with parts of the document. The
"twigs".
I personally believe XML::LibXML is overcomplicated, but some people
seem to like it.
