I tried to cover a little bit of this in both my xml.com article on
XPathScript [1], and my AxKit talk at ApacheCon. Basically, procedural
code is great for data oriented XML structures, but almost useless for XML
mixed content. For mixed content you really need declarative code. I hope
that XPathScript provides a nice feeling for those who need or want both
(and of course those who like Perl!).
