I extended your first= approach:

in the flow script I use the= inputStream from the uploaded file to feed a XpathEvaluator class in combi= nation with the an xpath expression.

var inputStre= am =3D widget.getValue().getInputStream();
var xpath =3D "/my/path/to/el= ement";
var result =3D cocoon.getComponent('XPathEvaluator').evaluate(in= putStream, xpath);

Thanks again, Matthias

I = actually had a similar need the other week and while I have used some XML-J= AVA mappers like Castor and XStream in the past I decided to try another ap= proach where I generated JSON which can be used from flowscript:
 
 =
/** flowscri= pt function to generate the pdf **/
&nbs= p;
&n= bsp;
f= unction json2Object(json) {
         = ;       return eval("(" + json + ")");=
}
 
 
function generatePDF= () {
&= nbsp;   var id =3D cocoon.parameters.id;  //e.g. PH3330L
 
 =
 = ;   //var fileName =3D cocoon.getComponent('fileNameExtractor').getFileName(id);
 
 &= nbsp;  var output =3D new Packages.java.io.ByteArrayOutputStream();
 <= /span>
 =    var uri =3D "extractData/" + id;  
   &nbs= p;//now we invoke a pipeline which returns a JSON string. E.g:
    /**
   &n= bsp; *   {"id": "PH3330L","fileName": "PH3330L.pdf"},
   = ;  */
    cocoon.processPipelineTo(uri, null, output);=
 
    var= responseData =3D json2Object(output.toString());    =
 
 
 &nb= sp;  var response =3D cocoon.response;     &n= bsp;            = ;      
    response.setHeader(
   &nbs= p;            "Conte= nt-Disposition",
          &nbs= p;     "attachment; filename=3D" + responseData.fileNam= e;
&nb= sp;   );         <= /div>
  &= nbsp; cocoon.sendPage('source2pdf/' + id);
 
}
