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.

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

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.
