[xslt] [HELP] Parsing xml and xsl file and applying stylesheet question

[Brave <zimzum4 gmail com>]

This morning I was trying to compile the code I found on the XSLT Mailing List and adapting it to my need.

The compilation of the file is ok, but when I execute it, I receive this warning:

compilation error: element h1

xsltParseStylesheetProcess : document is not a stylesheet

xsltParseStylesheetDoc failed

I'm using Visual Studio 2010, libxml2-2.7.8 and libxslt-1.1.26-win32.

The xml and xsl files are grabbed from "http://www.zvon.org/xxl/XSLTutorial/Books/Output/example1_ch1.html" the first example (XSLT stylesheet 1).

Hope I gave you all the needed information, I'd like to understand what's the problem with my xml and xsl file.

Best Regards.
