RequestParameterAction question

[Anna Afonchenko <an...@ubaccess.com>]

Hi all.
I am using RequestParameterAction to process parameters given in http request.
My http request looks something like this:
http://localhost:8080/cocoon/test?e-mail=user@domain.com

here is my pipeline:

<map:match pattern="test">
    <map:act type="request">
        <map:parameter name="parameters" value="true"/>
        <map:generate src="testing/testPage.xml"/>
        <map:transform src="testing/stylesheet.xsl">
            <map:parameter name="e-mail" value="{e-mail}"/>
        </map:transform>
        <map:serialize type="xml"/>
    </map:act>
</map:match>

This way I pass the e-mail parameter to the stylesheet.
Now here is my question:
Can I preprocess the request parameter before passing it further?
E.g. in this case can I pass to the xsl instead of the whole e-mail parameter
something like: {substring-before('@',e-mail)} to pass only the username to xsl?

I know that in this case I don't really need it, because I can do this inside the xsl, but
I just give this as an example.
What I will realy need is for example to call another pipeline through the cocoon:// protocol
with part of the given request parameter that I want to extract.
Is it possible to do? Can somebody explain this to me?

Thank you very much for help.

Anna

Please look at the InputModules stuff. You can write your own module
that applies this function or -- in case of the jxpath-based modules
-- use arbitrary java methods on the values. Please look at the JXPath
documentation at jakarta.apache.org for specifics of JXPath.

It is possible and since you can add parameters using the HTTP GET
syntax i.e "cocoon://pipeline?one={e-mail}&amp;two={foo}"
