How to use XPath in FireFox?

I Have a web applicaton and now I want to improve it so it works in FireFox. My problem is how to use XPath in a cross-browser manner.

I have this script:

var oXmlDoc = new ActiveXObject("Microsoft.XMLDOM");
        oXmlDoc.async = "false";
        oXmlDoc.loadXML(document.getElementById(MasterObj + "txtMenu").value);
        var xmlNodes = oXmlDoc.documentElement.selectNodes("/FormGeneratorEntity/GetMenu[TemplateID=" + obj.value + "]");
  var len = xmlNodes.length
        for (var i = 0; i < len; i++) {
   alert(xmlNodes.item(i).selectSingleNode('Title').text)
}

And my xml string looks like this:

 <FormGeneratorEntity><GetMenu><Title>MyTitle</Title><Val>MyValue<Val/></GetMenu></FormGeneratorEntity>

How can I make this work in Firefox?

Your question is not "How to use XPath in Firefox", but "How to create a XML document from a string (in Firefox)".

The answer to that question is the DOMParser, more specifically the parseFromString method:

oXmlDoc = new DOMParser().parseFromString(content_string, "text/xml");

Implemented in your current code:

var oXmlDoc,
    content_string = document.getElementById(MasterObj + "txtMenu").value;
if (window.DOMParser) {
    oXmlDoc = new DOMParser().parseFromString(content_string, "text/xml");
} else if (window.ActiveXObject) {
    oXmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    oXmlDoc.async = "false";
    oXmlDoc.loadXML(content_string);
} else {
    // Not supported. Do something
}

If you're still looking for excellent documentation on XPath, have a look at the Mozilla Developer Network: XPath.

Can you use jQuery? If so, it would be a much more browser-friendly solution.
