hi,
your example is not going to work at all, ..., i suggest you to take a
look at java source code generated from xsp page, this code is located
somewhere in tomcat/work/localhost*/cocoon/org/apache/www/...your_xsp.java,
you'll find there that element <person-colour> and Java variable person are
cmpletely unrelated, you might try in xsp something like
<xsp:element name="person-colour">
<xsp:attribute name="person"><xsp-request:get-parameter
name="person"/></xsp:attribute>
</xsp:element>
this way the XML output generated by XSP page will contain somewhere the
element
<person-colour person="Peter"/> // or whatever your request parameter was
then you can match in your XSL the element person-colour and use its attribute
@person to take a value from external xml file, ...
cheers,
martin
