Question

我是Android的新手，我不知道哪个解析器最好，所以你们可以帮助我解析这个XMl文件

<poem name="P01">
    <stanza name="P1S1">
        <Line name="P1S1L1">
            <word name="P1S1L1W1">Twinkle</word>
            <word name="P1S1L1W2">twinkle</word>
            <word name="P1S1L1W3">little</word>
            <word name="P1S1L1W4">star</word>
        </Line>
        <Line name="P1S1L2">
            <word name="P1S1L2W1">How</word>
            <word name="P1S1L2W2">I</word>
            <word name="P1S1L2W3">wonder</word>
            <word name="P1S1L2W4">what</word>
            <word name="P1S1L2W5">you</word>
            <word name="P1S1L2W6">are</word>
        </Line>

    </stanza>

    </poem>

我给每个标签提供了Id或Name，我想使用该名称/ ID而不是标签名称来读取标签的文本/值因为如果我想阅读文本奇迹所以有很多单词标签，那么我怎么能用该名称/ ID读取标签的单个值/文本。所以请给我这个建议对不起我的英语不好 Thanx提前

Answer 1

很容易。您应该使用DOM解析器。

这是link。

您也可以进行SAX解析，但这很复杂。

Answer 2

使用此代码：

private static void xmlParser() {
    try {
        String filepath = "yourfile.xml";
        DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
        Document doc = docBuilder.parse(filepath);
        // Get the root element
        Node min = doc.getElementsByTagName("poem").item(0);
        NamedNodeMap attr = min.getAttributes();
                    // get the value of the name=
        Node nodeAttr = attr.getNamedItem("name");
                    //if you want to change the value of the name use 
                    nodeAttr.setTextContent("new name value");
                    //if you want to get the value between >value< use 
                    nodeAttr.getTextContent()
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        DOMSource source = new DOMSource(doc);
        StreamResult result = new StreamResult(new File(filepath));
        transformer.transform(source, result);
    } catch (ParserConfigurationException e) {
            e.printStackTrace();
    }
     catch (IOException ioe) {
            ioe.printStackTrace();
        } catch (SAXException sae) {
            sae.printStackTrace();
        } catch (TransformerConfigurationException e) {

            e.printStackTrace();
        } catch (TransformerException e) {

            e.printStackTrace();
        }
}

只需对上面的其他标签应用以上内容..
