在 Java 中读取和解析任意 xml 结构？

XML 解析新手。我需要读取一组任意 XML 文件。它们都应该是 POX，如以下格式：

<someThing>
  <property1>blah blah blah</property1>
  <property2>blah blah blah</property2>
</someThing>

或以下：

<thingList>
  <items>
    <otherThing>
      <prop3>blah blah blah</prop3>
      <prop4>blah blah blah</prop4>
    </otherThing>
    <otherThing>
      <prop3>blah blah blah</prop3>
      <prop4>blah blah blah</prop4>
    </otherThing>
  </items>
</thingList>

所以我事先不知道元素的名称。我的问题是是否有任何 Java 库可以不按节点名称或节点属性而是按结构来处理 XML 中的读取？

New to XML parsing.I need to read a group of arbitrary XML files. They are all supposed to be POX, like the following format:

<someThing>
  <property1>blah blah blah</property1>
  <property2>blah blah blah</property2>
</someThing>

or the following:

<thingList>
  <items>
    <otherThing>
      <prop3>blah blah blah</prop3>
      <prop4>blah blah blah</prop4>
    </otherThing>
    <otherThing>
      <prop3>blah blah blah</prop3>
      <prop4>blah blah blah</prop4>
    </otherThing>
  </items>
</thingList>

So I won't know the name of the elements beforehand. My question is if there is any Java library that handles reading in XML not by the name of the node or the node's attribute, but by structure?

使用 getRootElement 方法可以获得 xml 文件的根元素。获取根元素后，您必须指定要获取的元素的 xml 路径。我已经使用它为“items/otherThing/prop3”编写了内容，您将获得 prop3 标签值。

File fXmlFile = new File("test.xml");
     SAXBuilder builder = new SAXBuilder();
     Document document = builder.build(fXmlFile);
     Element beans = document.getRootElement();

     Element dbUrlElementHost = (Element) XPath.selectSingleNode(beans,"items/otherThing/prop3");
     dbUrlElementUsername.getValue()+"";

Using getRootElement method you can get the root element of the xml file. After getting the root element you have to specify the xml path which the element you want to get. I have written for "items/otherThing/prop3" using this, you get your prop3 tag value.

File fXmlFile = new File("test.xml");
     SAXBuilder builder = new SAXBuilder();
     Document document = builder.build(fXmlFile);
     Element beans = document.getRootElement();

     Element dbUrlElementHost = (Element) XPath.selectSingleNode(beans,"items/otherThing/prop3");
     dbUrlElementUsername.getValue()+"";
