Newbie: Generating XML before rendering HTML

[an...@wipro.com]

Hi,

I have the sitemap.xmap configured as below.



What we are tyring to do is to get data from the database, store it into
session and render it as HTML.



I would like to know how we can generate a  xml file to a local directoy
before it gets rendered to the brower.

I need this , as I want to understand what is the content of the XML
being used , so that I can write my . xsl file correctly.



Would appreciate if some one can tell me how to achieve this or throw
some pointer to achieve the same.



Thanks in advance.

Have a nice day.

Regards,







<map:pipeline>

    <map:match pattern="test/*/ ">

      <map:aggregate element="page" label="page-content">

        <map:part src="cocoon:/test-contents/" />

        <map:part src="cocoon:/actions" />

        <map:part src="cocoon:/test-meta/{1}" strip-root="true" />

      </map:aggregate>

      <map:call resource="convertTo-html">

        <map:parameter name="action" value="./act" />

      </map:call>

    </map:match>

        <map:parameter name="attr-name" value="{1}" />

        <map:parameter name="root-element" value="content" />

      </map:generate>

      <map:transform type="paginate"

      </map:transform>

      <map:serialize type="xml" />

Hi Anand,
As Derek mentioned, it is unusual to want to write the XML
to a file before processing it. If you really want to do this,
you can use the SourceWritingTransformer (we have used this
successfully). But if you just want to see the XML for the sake
of debugging or knowing what's coming down the pipeline, the
easiest way is just to let the XML come down the pipeline
unprocessed. E.g. change your "test/*/" pattern to:

    <map:match pattern="test/*/ ">
      <map:aggregate element="page" label="page-content">
        <map:part src="cocoon:/test-contents/" />
        <map:part src="cocoon:/actions" />
        <map:part src="cocoon:/test-meta/{1}" strip-root="true" />
      </map:aggregate>
	 <map:serialize type="xml" />
    </map:match>
 
This will let the XML show up in the browser, and you can save it
to a file.

Another way to do this is to use views. Views will let you "peek"
into a stage of the pipeline without changing the sitemap.
With your "test/*/" pattern:

    <map:match pattern="test/*/ ">
      <map:aggregate element="page" label="page-content">
        <map:part src="cocoon:/test-contents/" />
        <map:part src="cocoon:/actions" />
        <map:part src="cocoon:/test-meta/{1}" strip-root="true" />
      </map:aggregate>
      <map:call resource="convertTo-html">
        <map:parameter name="action" value="./act" />
      </map:call>
    </map:match>

you can add this to the <map:views> section of your sitemap:
    <map:view name="page-content" from-label="page-content">
      <map:serialize type="xml"/>
    </map:view>

And then when you access the URL, add a "cocoon-view=" parameter:
    http://myhost/cocoon/.../test/foo/ ?cocoon-view=page-content

By the way you may want to remove the spaces within quotes
in your match patterns and resource names. Then the above URL would be
    http://myhost/cocoon/.../test/foo/?cocoon-view=page-content

HTH,
Lars
