Dear friends,
I've been looking for this feature for a week already, nobody and nowhere
can't give me a definite answer.
I want to extract data with XPath from an XML file whoes name depends on
request parameters.
The XMLFileModule is statically configured, so the file name is fixed.
Please, is it possible without writing my own module?
I ran across this thread today, because I need exactly this very same
thing! :-) Alexander, I saw another post of yours around the same
time, maybe on the dev group or somewhere... I too was faked out a
little bit by the mention of "dynamic" configuration" in the comments
for XMLFileModule. It looks like that stuff (the modConf parameter to
getAttribute() and friends) is there for use by other Cocoon
components... see LinkRewriterTransformer for an example. If you think
about it, for what you wanted (and what I want :-), the only way to
specify the source name would have to be in the attribute name syntax
for the module. If you don't see it there, then it ain't there and
this module doesn't do what we want :-/.
So, what I'm after would be an XPathModule, invoked in the sitemap like this:
{xpath:source-uri#xpath-expression}
e.g. (in the particular appl'n I have for this just now :-):
<map:relocate-to uri="{xpath:{1}#/relocate-to/@uri}" />
It looks like a reasonable strategy would be to factor most of
XMLFileModule into a new class AbstractXMLFileModule, and then extend
this to implement XPathModule. Comments?
