IE workaround for XPathEvaluator

Posted on by Community Member

Hi, I have encountered a problem where I am trying to retrieve the option set from the forms account to get the selected option text and put in a text field on the quote form. The problem is that while using the SDK.Metadata the function XPathEvaluator is coming up as undefined as I am using IE, does anyone know a workaround?

    You can use selectNode() and selectSingleNode() on the DOM Document object instead for IE browser to parse the xml.

    Hi Chitra

    This is all new to me, could you perhaps give some example code of how this is done?

    here is sample code that may help you to get started

    var resultRes = httpReq.responseXML;

    var errorCount = resultRes .selectNodes('//error').length;

    alert("After the result XML "+resultRes .toString() + " ::::");

    var username = resultRes .selectSingleNode("//q1:new_jabberusername").nodeTypedValue;

    var pass = resultRes .selectSingleNode("//q1:new_jabberpassword").nodeTypedValue;

    Hi,

    Thank you, unfortunately this has gone completely over my head, I am using the SDK.Metadata supplied with by Microsoft, the following code is where the function is crashing out

      else {

        var xpe = new XPathEvaluator();

        var xPathNode = xpe.evaluate(xpathExpr, node, SDK.MetaData._NSResolver, XPathResult.FIRST_ORDERED_NODE_TYPE, null);

        return (xPathNode != null) ? xPathNode.singleNodeValue : null;

       }

    I tried running sdk Meta data script in my org and i did not see this error message.

    Anyway try with below code and should work without any error

    if (typeof (node.selectSingleNode) != "undefined") {

      return node.selectSingleNode(xpathExpr);

     }

     if (XPathEvaluator) {

         var xpe = new XPathEvaluator();

         var xPathNode = xpe.evaluate(xpathExpr, node, _NSResolver, XPathResult.FIRST_ORDERED_NODE_TYPE, null);

         return (xPathNode != null) ? xPathNode.singleNodeValue : null;

     }

     else {

         return node.selectSingleNode(xpathExpr);

     }
