Ntoe: Everything works fine with this. However, you can use <xsl:include> with a string for xslt_process, so I need to send the string with xslt_output_begintransform() in order for all includes to happen. I need to use that function, because I will not know what all xsl files will need to be included with every parsing; template designers add and change things all the time; plus it would be nice if the transformation was as close to standards as possible. Note: This seg fault problem has been a problem from php 4.0.3+; I have also tried the CVS copies and xslt does not seem to work in that distribution at all (compile with --with-sablot-xslt; according to configure --help). I can take these same three files (converting the php file to straight XML) and use sabcmd -L log -m index.xsl index.xml index.html and it is transformed without a hitch. This is definitely an issue with PHP. I have also created the XML file with the PHP DOM functions and echoing the tree out (as per the manual example) in between xslt_output_begintransform() and xslt_output_endtransform() and it seg faults as well. Any questions let me know. Micah
