[xslt] Using external resources

[Mark Howe <mark cyberporte com>]

Hi,

I'm using LibXSLT for a web project via perl CPAN packages. At various 
points I need to access external resources, eg databases, or do the sort 
of calculations at which XSLT doesn't excel, eg crypting passwords. I'm 
currently using the document() function to call local CGI scripts, which 
works, but I was wondering what other options exist, specifically any 
supported document() protocols other than http and any ways to link to 
external scripts or libraries without recompiling LibXSLT. The answer 
appears to be implementation-dependent in the XSLT 1.0 spec, and I 
haven't found any LibXSLT documentation that addresses this sort of 
issue. All information appreciated.

Regards,

Mark Howe
