Request parameters to specify an input file
Hi,
I'd like to use the value of a request parameter to specify a file to
aggregate with my input.
For example, when the URI is
http:localhost:8888/cocoon/dir/whee.xml?sequence=zoom.xml
I'd like to have the functional equivalent of
<map:aggregate element="goforit">
<map:part src="{1}/{request-param:sequence}"/>
<map:part src="{1}/{2}"/>
</map:aggregate>
Except this gives me an error when the parameter is missing, where I
need fallback behavior (for example, just adding nothing would do).
Thanks for any help you can offer.
Cheers,
Wendell

Or, depending on what he wants to achieve, resource-exists action/
selector might be even better ;-)

A selector base on request parameter values should do.
Something like this (off the top of my head, so it may contain errors)...
<map:select type="request-parameter">
<map:parameter name="parameter-name" value="sequence"/>
<map:when test="">
<map:aggregate element="goforit">
<map:part src="{1}/default-sequence.xml"/>
<map:part src="{1}/{2}"/>
</map:aggregate>
</map:when>
<map:otherwise>
<map:aggregate element="goforit">
<map:part src="{1}/{request-param:sequence}"/>
<map:part src="{1}/{2}"/>
</map:aggregate>
</map:otherwise>
</map:select>
