in reply to Design recommendation for parsing and creating XML files.

Check out XML::LibXML::SAX::Builder. It builds a DOM from a SAX stream. From there you can use XPath on the data set, and even serialise back to SAX when you're done if you want to. There's nothing in the SAX spec that says you shouldn't be able to use XPath on the data, or shouldn't build a DOM with it. SAX just happens to be the universal plumbing.

Also you might want to check out Barrie Slaymaker's XML::Filter::Dispatcher, which allows you attach to a SAX pipeline and dispatch to methods/functions based on XPath's specified in the constructor. Rather like XML::Twig, but better ;-)

I've been meaning to write a node about just how great SAX is for a while now, maybe it's time I just did it.

    Note that, in order not to be outdone, XML::Twig supports SAX (SAX1 and SAX2 actually) output in version 3.05. I am still pondering whether to include SAX input in the main module or to create a separate XML::TwigSAX, but I will get there, and join the happy Perl/SAX family ;--)

    Plus does XML::Filter::Dispatcher (which looks pretty cool BTW) have a tee-shirt? ;--)

    Thanks so much. I'll look into these modules.
