在 Android 上解析 XML [英] Parse XML on Android

问题描述

我正在尝试在 Android 应用程序中为我们的计费系统使用 API，但我无法弄清楚如何解析它返回的 XML.到目前为止，这是我的函数的样子......

I am trying to use the API for our billing system in an Android Application, but I am having trouble figuring out how to parse the XML that it returns. Here is what my function looks like thus far...

public void ParseData(String xmlData)
{
    try
    {
        // Document Builder
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = factory.newDocumentBuilder();

        // Input Stream
        InputSource inStream = new InputSource();
        inStream.setCharacterStream(new StringReader(xmlData));

        // Parse Document into a NodeList
        Document doc = db.parse(inStream);
        NodeList nodes = doc.getElementsByTagName("ticket");

        // Loop NodeList and Retrieve Element Data
        for(int i = 0; i < nodes.getLength(); i++)
        {
            Node node = nodes.item(i);

            if (node instanceof Element)
            {
                Element child = (Element)node;
                String id = child.getAttribute("id");
            }
        }
    }
    catch(SAXException e)
    {

    }
}

这是返回的 XML 数据的样子.我需要遍历每个元素并拉出每个元素，但我不知道如何使用 DOM 解析器来做到这一点.

and here is what the XML data looks like that is returned. I need to loop through each and pull each element out, but I cant figure out how to do that with the DOM parser.

推荐答案

1. 在库文件夹中添加java-json.jar
2. 编译文件 ('libs/java-json.jar')//将此行添加到您的构建中

1. Add java-json.jar in library folder
2. Compile files ('libs/java-json.jar') //add this line into your build

这里是将 xml 响应转换为 json 响应的代码:

Here is the code to convert xml response to json response:

JSONObject jsonObj = null;
try {
        jsonObj = XML.toJSONObject(response.toString());
} catch (JSONException e) {
        Log.e("JSON exception", e.getMessage());
        e.printStackTrace();
}
