Hi all

I am using below code

function ShowConfiguration() {
debugger;
var serverUrl = window.parent.Xrm.Page.context.getClientUrl();
var webResourceName = "apikey"
var webResourceURL = serverUrl + "/WebResources" + "/" + webResourceName
var nodePath = "//Configuration";
var XmlDoc= new ActiveXObject("Microsoft.XMLDOM");
XmlDoc.preserveWhiteSpace = true;
XmlDoc.async = false;
XmlDoc.load(webResourceURL);
var nodelist;
nodelist = XmlDoc.selectNodes(nodePath);
document.getElementById('APIkey').value = nodelist[0].selectSingleNode("APIkey").nodeTypedValue;
}

With the following xml file

<?xml version="1.0" encoding="utf-8"?>
<Configuration>
<APIkey>ab15c4d132d2afuholiklhkjkl2e5a-us14</APIkey>
</Configuration>

This code giving me this

Hello,

Your code seems good.

If you add watch for nodelist[0].selectSingleNode("APIkey").nodeTypedValue, I think that you'll get your value.

The error message says that "document.getElementById('APIkey')" is null, so it cannot set its value. Please make sure that you have this element APIkey (is it its real name? Not a simple copy paste from the Xml node?) on your form.

Hi Abdul Wahab,

Can you please verify if the HTML page on which you are running the code has an element/control named 'APIkey'?

"document.getElementById('APIkey')' itself is null, which is why when you try to do append a '.value' to it, you are getting a null reference error.

PS: I would not recommend using the ActiveX library to read the XML file, as most browsers (other than IE) does not extend support for it.

Strongly recommend you to use jQuery library to read the XML file.
