OK, I'm going to try and be a little less inflamatory now :-)
The reason I think XML should be given more time of day is because of the tools. Period. Those tools exist and are well thought out and work because a lot of thought has been put into them, not just in the Perl world, but in the entire development community. There's a lot of chopping and munging you can do with those tools really easily, and sometimes the design of them and the re-use enabled by them (I'm talking about SAX filters here in particular) makes it a cost effective weapon for your business. I do find Perl hackers very quick to dismiss the research and study that has gone on for years in more academic areas of computer science, often with good reason, but one case in point for XML is XSLT, which is an incredibly mature technology, but Perl hackers (including myself at one time) dismiss it because it's verbose and fugly, rather than look at some of the reason behind the madness.
But aside from all that, I really don't want to try and convince you that you must use Perl and XML. I've obviously written something completely wrong to make you think that, and for that I appologise. Let me clarify exactly what I want to happen: I want people to stop asking why Perl sucks at XML (and that includes you mirod!). Because people like mirod and myself have worked really damned hard in the past few years to make sure that it doesn't. And really - it doesn't. Perl absolutely rocks at XML, as people who have actually used it compared to the competition will testify.
So I guess what I'd love to see is those people who have been successful at using it should make sure that other people know their success story. Because the XML world believes that we all use regexps to process our XML, and that Perl really sucks for XML, and that annoys me, because it's a myth. And it annoys me because I put in a lot of grunt work to make it not true.
