获取标签以及值?XML [英] Getting tag as well as the values? XML

问题描述

我将以下 XML 作为字符串传递.

I have the following XML being passed as String.

<?xml version="1.0"?>
 <tagMain>
    <tag1>
      <a>
        <a>1</a>
        <b>2</b>
        <c>3</c>
        <d>4</d>
      </a>
      <b>5</b>
      <c>6</c>
      <d>7</d>
      <e>8</e>
      <f>9</f>
    </tag1>

    <tag2>
        <r>
            <r1>10</r1>
            <r2>11</r2>
            <r3>12</r3>
            <r4>13</r4>
        </r>
        <b>14</b>
        <c>15</c>
        <d>16</d>
        <e>17</e>
        <f>18</f>
    </tag2>

    <tag3>
        <a>
            <a>1m</a>
            <b>2m</b>
            <c>3m</c>
            <d>4m</d>
        </a>
        <b>5m</b>
        <c>6m</c>
        <d>7m</d>
        <e>8m</e>
        <f>9m</f>
    </tag3>
</tagMain>

我调用了以下方法，该方法为每个标签获取值.

I calling the following method which is getting me values between for each tag.

public static void  SplitXml(String xml) throws ParserConfigurationException, SAXException, IOException {

        DocumentBuilder builder = DocumentBuilderFactory
                .newInstance().newDocumentBuilder();
        InputSource src = new InputSource();
        src.setCharacterStream(new StringReader(xml));

        Document docu = builder.parse(src);
        String tag1 = docu.getElementsByTagName("tag1").item(0).getTextContent();
        String tag2 = docu.getElementsByTagName("tag2").item(0).getTextContent();
        String tag3 = docu.getElementsByTagName("tag3").item(0).getTextContent();

}

当我运行上面的代码时:

when I run the above code:

tag1 = "123456789";
tag2 = "101112131415161718";
tag3 = "1m2m3m4m5m6m7m8m9m";

现在我回到我的问题，有没有一种方法可以获得标签以及每个标签的内部值:

Now my back to my question, Is there a way I can get the tags as well as the values inside the like such for each tag:

tag1 = "<tag1><a>
            <a>1</a>
            <b>2</b>
            <c>3</c>
            <d>4</d>
          </a>
          <b>5</b>
          <c>6</c>
          <d>7</d>
          <e>8</e>
          <f>9</f>
        </tag1>";

推荐答案

要么使用 LSSerializer (http://docs.oracle.com/javase/8/docs/api/index.html?org/w3c/dom/ls/LSSerializer.html) 或从 TransformerFactory 创建一个默认的 Transformer 然后你可以使用它来序列化一个 DOM 节点，传入一个 DOMSource 到 transform 方法 (https://docs.oracle.com/javase/7/docs/api/javax/xml/transform/Transformer.html#transform(javax.xml.transform.Source,%20javax.xml.transform.Result) 和一个 StringWriter 来收集结果.

Either use LSSerializer (http://docs.oracle.com/javase/8/docs/api/index.html?org/w3c/dom/ls/LSSerializer.html) or create a default Transformer from a TransformerFactory and then you can use that to serialize a DOM node, passing in a DOMSource to the transform method (https://docs.oracle.com/javase/7/docs/api/javax/xml/transform/Transformer.html#transform(javax.xml.transform.Source,%20javax.xml.transform.Result) and a StringWriter to collect the result.
