[Sab] xsl:include

[Thomas Bopp]

Hello!

I have the problem, that my xml/xsl content comes from a database. 
It seems like xsl:include does only work on the filesystem though. What
I 
would like to see is some kind of callback function that reads the
included
stylesheet from the given URI. So something like this would work:

sablot->set_uri_callback(func);

string func(string uri) {
  [...]
  return stylesheet-content-corresponding-to-uri;
}

Or is this already possible ?
