I have a problem with the below javascript file.
It's supplied by a third party, and worked only in IE QuirksMode.
Because I don't control the server backend, I can't change the API to JSON instead of SOAP, and avoid the completely braindead script altogether.
So I fixed the script so it also works in IE standards mode in IE 10/11 in a non-intranet environment.
While I was at it, I tried to fix it for Chrome, too.
I have only one remaining problem that I can't solve:
In function GetSOAPResponseEx i get the following error:
Uncaught NamespaceError: Failed to execute 'evaluate' on 'Document': The string '//ns1:RunLocatorResponse' contains unresolvable namespaces. SOAPAPI.js:64
XMLDocument.selectSingleNode SOAPAPI.js:64
GetSOAPResponseEx SOAPAPI.js:371
loadOrgRoleUserNames AWEMain.aspx:156
but I don't know why or how to fix it.
My hunch is that
objXmlDoc.setProperty("SelectionNamespaces", 'xmlns:ns1="http://tempuri.org/AWEService/API/WASAPI"');
does not exactly the same thing as
objXmlDoc = objXmlDomParser.parseFromString(szResponse, "text/xml");
objXmlDoc.documentElement.setAttribute("xmlns:ns1", "http://tempuri.org/AWEService/API/WASAPI");
But I don't know if the problem is setAttribute or something in selectSingleNode.
This are the XML files the selectSingleNode xpath query runs on:
-- Chrome
<?xml version="1.0" encoding="UTF-8"?>
