get string content from XQ_getXPath

Hi all

I try to fetch value form XQ_getXPath

But I cannot assign XQ_getXPath to a content part.

This is how I proceded:

    var inputPart = XQMessage.getPart(inPart);

    var indexInputPart=getPartIndex(inPart);

    var xpathNode=XQ_getXPath(xpath,indexInputPart);

    XQ_logInformation(xpathNode.enumerate().nextElement().textContent);

    var part=XQMessage.createPart();

    part.setContentId(outPart);

    part.setContent(xpathNode.enumerate().nextElement().textContent,"text/xml");

    XQMessage.addPart(part);

I return no value with xpathNode.enumerate().nextElement().textContent

Any idea?

Ciao

Giovanni
