如何通过删除xml标记来解析json
<?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>
<AddUserResponse xmlns="http://abcd.com/">
<AddUserResult>
{"clsError":{"ErrorCode":110,"ErrorDescription":"Email Already Exist"},"UserID":-1}
</AddUserResult>
</AddUserResponse>
</soap:Body>
</soap:Envelope>
我尝试了这段代码,结果被作为上述xml格式的响应字符串
String temp = result.substring(282, (length - 62));
System.out.println(temp);
JSONObject object = (JSONObject) new JSONTokener(temp).nextValue();
String query = object.getString("ErrorDescription");
在ddms中它说: org.json.JSONException:ErrorDescription没有值
答案 0 :(得分:1)
您没有正确解析json。这对于读取ErrorDescription是正确的:
JSONObject object = (JSONObject) new JSONTokener(temp).nextValue();
JSONObject childObject = object.getJSONObject("clsError");
query = childObject.getString("ErrorDescription");
此外,通过简单地获取xml的子字符串来获取json对象是不合适的。最好做一个有规律的xml解析来检索它,
