    I would need more examples on using rbv_api.evalXpath function. This is my error:

    /* Initialization code injected by validation and debug process */
    var rbv_debugFormula = true;
    /* End Initialization code injected by validation and debug process */

    var xmlString = rbv_api.getTextData("Upload", 12619109, "uploadf_document");

    //rbv_api.println("xmlString = " + xmlString);

    var myXpathstar = "/Tyres/*";

    var myXpathId = "Tyre/ID/text()";

    var myXpathnext = "Tyre/*";

    var loop = rbv_api.evalXpath(xmlString, myXpathstar);

    var loop2 = rbv_api.evalXpath(xmlString, myXpathnext);

    for (var k=0; k<loop2.length; k++) {

    var nodename1 = rbv_api.evalXpath(xmlString, myXpathnext).item(k).getNodeName();

    rbv_api.println("Name 1 = " + nodename1);


    var v_ID = rbv_api.evalXpath(xmlString, myXpathId).item(k).getNodeValue();

    rbv_api.println("ID = " + v_ID + " nummer " + k);

    var v_ID = "";


    }


    Name 1 = ID
    ID = 226368 nummer 0
    Name 1 = BACCode
    ID = 226367 nummer 1
    Name 1 = EANCode
    ID = 226369 nummer 2
    Name 1 = Definition
