跨浏览器 Javascript XML 解析 [英] Cross-Browser Javascript XML Parsing

问题描述

是否有任何跨浏览器/跨平台的方式来解析 Javascript 中的 XML 文件?

Are there any cross-browser / cross-platform ways to parse XML files in Javascript?

推荐答案

以下内容适用于所有主流浏览器，包括 IE 6:

The following will work in all major browsers, including IE 6:

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");
}

示例用法:

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

现场演示:

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");
}

var xml = parseXml("<foo>Stuff</foo>");
document.body.innerHTML = "Root element: " + xml.documentElement.nodeName;
