So this isn`t implemented ?
Is there something i can use? I really don't want to patch libxslt becouse 
this is an application for some clients. So i want to use standard library 
calls.

I must have been to unclear, what i ment is that i cant use a function call 
like xsltSaveResultToFd() i have to now acactly how large the string is after 
its parsed before its printed.
Thats why i want to have it in a string then i can call strlen() before 
printing. I'm building a very light weight web/xslt-server so i have to write 
the proper content-lenght http-header. I also want to be able to cache a 
transformation server side (html).

what i meant is that i parse the xml, find out the value of <?xml-stylesheet 
?>  and use the value to find out what xsl file to parse and use for the 
tranformation.
