I'm new at cocoon, but it seems to me a little blurry where the right place to do something... And I don't know for example, what can I do with an action, so I was experimenting some "techniques" to have my objective done, but what I'm looking for, is:
I've made a form to search for a term. When a user submit's the form, I merge that querystring (I know how to do it in XSP) with an URL, for instance: http://www.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=pubmed&term="trans genic"&retmax=200 In that example I've used "trangenic" as a search term. Them that site will return me XML data (mainly id's of related articles), and I must write it in a repository. Then I must build an harvester that will go the repository and fetch the metadata of each article id. I'm actually having trouble to understand, in what state of the pipeline will I do every task I need, I know that I can use a serializer to write the XML on disc, I can get querystring's in XSP, i can write XML on disc with a XSL also, so there are many many ways, and for newbies it's a little bit difficult to start with :| Currently I have the form like this in my sitemap.xmap: <map:match pattern="search"> <map:generate type="file" src="documents/search.xml"/> <map:transform type="xslt" src="stylesheets/page2html.xsl"/> <map:serialize type="html"/> </map:match> The form action is do-search and method POST. I wrote the next step like this: <map:match pattern="do-search"> <!-- validate form data --> <map:act type="form-validator"> <map:parameter name="descriptor" value="context://pubmed/descriptors/params.xml"/> <map:parameter name="validate" value="username"/> <!-- merge querystring with url and fetch data to repository --> here I don't know what's the best way to follow: - a transformer? - send the querystring (how to?) to a XSP that will do the rest </map:act> <!-- form data is null --> <map:redirect-to uri="error-form"/> </map:match> Another aproach i have is in the form, the action is "search.xsp" (I skip the validation procedure) and then I defined: <map:match pattern="procura.xsp"> <map:generate type="serverpages" src="xsp/procura.xsp"/> <map:transform type= "write-source"/> <map:serialize type="xml"/> </map:match> and in the XSP I can get the querystring (i've done it) but I don't know how to grab the XML data :| Can anyone give tips ? Thanks in advance for helping.
