我想解析 XML。我在下面發(fā)布我的 XML 響應(yīng)。在 pre標(biāo)記中，我得到了一個我想打印的 JSON，但我無法用我的代碼進(jìn)行解析。我正在發(fā)布我的代碼來解析這個 XML。private void xmlParsing(String qrCode) { try { qrCode = qrCode.replaceAll("[^\\x20-\\x7e]", ""); //loge("qrCode : " + qrCode); DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); Document doc = dBuilder.parse(new ByteArrayInputStream(qrCode.getBytes("utf-8"))); Element element = doc.getDocumentElement(); element.normalize(); NodeList nList = doc.getElementsByTagName("head"); loge("--df--nList.getLength()---"+nList.getLength()); for (int i=0; i<nList.getLength(); i++) { Node node = nList.item(i); if (node.getNodeType() == Node.ELEMENT_NODE) { Element element2 = (Element) node; } } } catch (Exception e) { e.printStackTrace(); } }<head></head><body> <pre style="word-wrap: break-word; white-space: pre-wrap;">{"status":true,"message":"Login Successfull","data":{"user":{"id":2,"name":"Rommy Garg","email":"rommy@signitysolutions.com","user_group_id":"2","company_id":2,"last_login":"2019-05-29 05:48:27","last_logout":"2019-05-28 10:33:39","profile_pic":null,"created_at":"2018-12-20 10:12:23","updated_at":"2019-05-29 05:48:27","sf_reference_id":"0056F00000BqMZSQA3","sf_setup":1},"company_logo":"http:\/\/staging.sales-chap.com\/dist\/uploads\/company\/1545300743.jpg","client_id":1,"client_secret":"IQ09J2BdDuc3lSKUJlQAp8uhCXRq+s2EucsBOb9rfjo="}}</pre></body>但我收到以下錯誤：org.w3c.dom.DOMException: 只允許一個根元素

好吧，正如錯誤所說，XML 只允許一個根元素。您可以圍繞收到的字符串創(chuàng)建一個假字符串：
qrCode = "<html>" + qrCode + "</html>";
