can't output text before document element

[Henrik Hofmann]

Hi,   im really new new to Cocoon and have a, as I think, trivial Question for people used to Cocoon. I'm sorry but I couldn't sind any Solution on the net.   Im trying to learn how cocoon works so i copied the example from the cocoon website. Whe I try to acces this page i get the following error message:   can't output text before document element   the xml and xsl files are very simple, and i cant se any bug in them.   <?xml version="1.0"?> <?cocoon-process type="xslt"?> <?xml-stylesheet href="testsheet.xsl" type="text/xsl"?> <page>  <title>Hello World!</title>  <content>   <paragraph>This is my first Cocoon page!</paragraph>  </content> </page>     the testsheet.xsl   <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> </xsl:stylesheet>   Thx in advance for any hint.
