How to Parse XML Files Reliably Across Browsers, Including Internet Explorer 6?

Cross-Platform XML Parsing with JavaScript

Parsing XML files in JavaScript can be challenging due to cross-browser and platform compatibility issues. This article explores reliable methods that work across major browsers, including Internet Explorer 6.

Cross-Browser XML Parsing

The following code snippet provides cross-browser compatibility for parsing XML files:

var parseXml;

if (typeof window.DOMParser != "undefined") {
    parseXml = function(xmlStr) {
        return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
    };
} else if (typeof window.ActiveXObject != "undefined" &&
       new window.ActiveXObject("Microsoft.XMLDOM")) {
    parseXml = function(xmlStr) {
        var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(xmlStr);
        return xmlDoc;
    };
} else {
    throw new Error("No XML parser found");
}

This code checks if the DOMParser interface is supported by the browser. If not, it uses the ActiveXObject for Internet Explorer. Otherwise, it throws an error if no XML parser is available.

Example Usage

To parse an XML string, simply call the parseXml function:

var xml = parseXml("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);
