Chrome更新后XSLT文档加载失败的解决方案

function loadXSLTDocument(url) {
    return new Promise(function (resolve, reject) {
        var req = new XMLHttpRequest();
        req.open("GET", url);

        // 针对旧版IE兼容性处理，如果XSLTProcessor未定义，尝试使用msxml-document
        if (typeof XSLTProcessor === 'undefined') {
            try {
                req.responseType = 'msxml-document';
            } catch (e) {
                console.error('Error setting responseType for IE compatibility:', e);
            }
        }

        // 核心解决方案：强制Chrome将响应解析为XML
        // 这解决了Chrome更新后responseXML为空的问题
        req.overrideMimeType("text/xml"); 

        req.onload = function () {
            if (req.status >= 200 && req.status < 300) {
                // 现在this.responseXML应该能正常获取到解析后的XML文档了
                if (this.responseXML && this.responseXML.documentElement) {
                    resolve(this.responseXML);
                } else {
                    // 如果responseXML仍然无效，但responseText可用，则尝试手动解析
                    console.warn("responseXML is empty or invalid, attempting to parse responseText.");
                    try {
                        const parser = new DOMParser();
                        const xmlDoc = parser.parseFromString(this.responseText, "application/xml");
                        if (xmlDoc.documentElement && !xmlDoc.getElementsByTagName("parsererror").length) {
                            resolve(xmlDoc);
                        } else {
                            reject(new Error("Failed to parse XML from responseText."));
                        }
                    } catch (e) {
                        reject(new Error("Error parsing XML from responseText: " + e.message));
                    }
                }
            } else {
                reject(new Error("Network response was not ok. Status: " + req.status));
            }
        };

        req.onerror = function () {
            reject(new Error("XMLHttpRequest failed for URL: " + url));
        };

        req.send();
    });
