xml的解析

后端返回的数据是xml格式的,以前做的项目都是json.稍微了解了下dom4j.

返回的数据

response = <?xml version="1.0" encoding="UTF-8" ?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><testJsonResponse xmlns="http://qcode.sia.org/"><result>%7B%22%u4F60%u4F20%u5165%u7684abc%22%3A124%2C%22%u4F60%u4F20%u5165%u7684def%22%3A%22iikkkk%22%7D</result></testJsonResponse></soap:Body></soap:Envelope>

Document document = DocumentHelper.parseText(response);
//获取文档根节点
Element root = document.getRootElement();
//取各个节点下内容
Element Body = root.element("Body");
Element testJsonResponse = Body.element("testJsonResponse");
Element result = testJsonResponse.element("result");
resultInXML = result.getStringValue();

这个resultInXML就是result里的内容%7B%22%u4F60%u4F20%u5165%u7684abc%22%3A124%2C%22%u4F60%u4F20%u5165%u7684def%22%3A%22iikkkk%22%7D

通过URL解码

public static String unescape(String src) {
    StringBuffer tmp = new StringBuffer();
    tmp.ensureCapacity(src.length());
    int lastPos = 0, pos = 0;
    char ch;
    while (lastPos < src.length()) {
        pos = src.indexOf("%", lastPos);
        if (pos == lastPos) {
            if (src.charAt(pos + 1) == 'u') {
                ch = (char) Integer.parseInt(src.substring(pos + 2, pos + 6), 16);
                tmp.append(ch);
                lastPos = pos + 6;
            } else {
                ch = (char) Integer.parseInt(src.substring(pos + 1, pos + 3), 16);
                tmp.append(ch);
                lastPos = pos + 3;
            }
        } else if (pos == -1) {
            tmp.append(src.substring(lastPos));
            lastPos = src.length();
        } else {
            tmp.append(src.substring(lastPos, pos));
            lastPos = pos;
        }
    }
    return tmp.toString();
}

得到需要的数据      {"你传入的abc":124,"你传入的def":"iikkkk"}

下个项目要用到,先写在这里记录一下.
