Subject Re: Hand over XSL variable value - wrong list?
Date Wed, 28 Jul 2010 08:48:38 GMT
XML is generated via a generator.

<data>
	<name>file</name>
	<value>Albatross</value>
	<temp.path>/tmp/files/xyz/</temp.path>
</data>

A transformation occurs so that the XML looks like ...

<files>
	<file name="Albatross">/tmp/files/xyz/Albatross</file>
</files>

Later in the pipe, and action could be to do something to the file (Compress it for example)

something like <map:act type="doMagic" src="{xpath:/files/file[@name='Albatross']/text()}"}>
	... do some other stuff...
</map:act>

Having spoken with the OP, theyare looking for a way to pass the value of the file element
in the transformed XML to the
sitemap. Maybe I've missed something obvious but I would have thought this functionality would
be present in the framework.

My assumption is that the DOM is held in memory somewhere after generation and passed to the
various transformers before
eventually being serialised. Surely there is a way to access the content of the DOM prior
to serialisation. Does anyone
know how?
