Maintaining request in match string.

[Joel P W Pitt <jp...@student.canterbury.ac.nz>]

Hi there,

I've tried several times to get help here with no luck, so I thought I'd
resort to a more general question.

Is it possible to use a matcher to match against the request string?
For example:

If I had the URL
http://localhost/info.html?45,23

Could I use a matcher in this manner:
<map:match pattern="info.html?*,*">
            <map:parameter name="x" value="{1}"/>
            <map:parameter name="y" value="{2}"/>
    <!--do stuff here-->
</map:match>

I've been fretting about how to retrieve image map
coordinates in cocoon. So far I've come to the conclusion
that you can't, but I'd love for someone to prove me wrong! ;-)

I'm using flowscript, and I thought it might be possible to retrieve the
request string through the cocoon request object. But there isn't any
such method that I'm aware of :-(

Any help would be much appreciated!!

Thanks,
Joel

Try to use the regexp matcher instead of the simple glob pattern
matcher:

<map:match type="regexp" pattern="info.html\?(\d+),(\d+)">

please check that \d (=decimal) and the escaping of brackets is
correct. I'm always struggling with tool takes which flavour of
regular expressions.... if \d is unknown, you could replace it with
[1-0] or [1234567890]
