Question

我想解析XML。我在下面发布我的XML响应。在里面 pre 标记我得到一个要打印的JSON，但无法解析我的代码。我正在发布代码以解析此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();
        }
    }

但是我遇到了以下错误：

org.w3c.dom.DOMException：仅允许一个根元素

好吧，正如错误所说，XML只允许一个根元素。您可以在收到的字符串周围创建一个假的：

qrCode = "<html>" + qrCode + "</html>";
