namespaces in root element of xsp generated page

[Simon Stanlake <si...@tradebytes.com>]

Hi,
 
I've got an xsp page that I would like to have generate xml that looks
like the following...
 
<root xmlns:foo="http://www.foo.com">
    <data>hello</data>
</root>
 
Problem is i'd like to have the foo namespace be dynamic, ie: come from
a form variable or database or something. I can add dynamic namespace
declarations inside the body of the xml document by going
 
<root>
    <xsp:logic>
        this.contentHandler.startPrefixMapping(myprefix,myuri);
    </xsp:logic>
    <data>hello</data>
</root>
 
which will add a declaration inside the <data/> element, but any content
inside <xsp:logic/> tags that is outside the first non-xsp element will
not be executed inside the generate() function, so this technique does
not work with the root element.
 
Is there a way to add a dynamic namespace declaration to the root
element of an xsp-generated xml document? I've thought of intercepting
the contentHandler and replacing with my own that does a
startPrefixMapping() inside the body of startDocument, but I'm looking
for something easier first.
 
thanks in advance,
 
Simon

Have a look at cocoon-2.1.x\src\blocks\xsp\samples\java\cacheable.xsp. 
It shows the usage of how additional java code can be added under 
xsp:page/xsp:logic. This _might_ help.
