Thanks for the quick response.
Actually I already know how to rename a file, although my approach isn't that elegant as yours. But what I need to know is the way I can access the uploaded xml file with XPath to read the information that I need. In other words: the magic that happens inside your PrototypeFileNameExtractor. String id contains the filename, how do I create a dom object with it?

There are many ways to accomplish this but below a possible approach:

/**** Java Component to extract the filename **/

public interface FileNameExtractor {

public String getFileName(String id);

}

public class PrototypeFileNameExtractor implements FileNameExtractor {

public String getFileName(String id) {

//TODO extract the fileName from the xml file identifiable by {id} e.g.

}

/** flowscript function to generate the pdf **/

function generatePDF() {

var id = cocoon.parameters.id;

var fileName = cocoon.getComponent('fileNameExtractor').getFileName(id);

var response = cocoon.response;

response.setHeader(

"Content-Disposition",

"attachment; filename=" + fileName + ".pdf"

);

cocoon.sendPage('source2pdf/' + id);

}

Sitemap:

----------

<!--

{1} id: unique identifier for the source xml used to generate the PDF

-->

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

<map:call function="generatePDF">

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

</map:call>

</map:match>

<map:match pattern="source2pdf/*">

<map:generate src="source/{1}.xml"/>

<map:transform src="xslt/source2poi.xslt"/>

<map:serialize type="pdf"/>

</map:match>

Subject: [C2.2] Get Element from uploaded file

Hi there,

I do some xml -> pdf transformation using Coocon 2.2 and fop. My output file name must contain a string that's in a certain element of my uploaded file.

I wonder how to access my uploaded file to extract the values?

Do I need to access it via control flow?

Is there something like a XPath evaluator?

Matthias
