解析 XML 个带有文本的自闭合标签

Question

大家好，我正在尝试解析我拥有的 XML 文件的这一部分。我遇到的问题是文本包含很多自关闭标签。我无法删除这些标签，因为它们为我提供了一些索引详细信息。我怎样才能访问没有所有 "Node" 标签的文本？

<TextWithNodes>
 <Node id="0"/>A TEENAGER <Node
id="11"/>yesterday<Node id="20"/> accused his parents of cruelty
by feeding him a daily diet of chips which sent his weight
ballooning to 22st at the age of l2<Node id="146"/>.<Node
id="147"/>
</TextWithNodes>

Answer 1

使用 XML 解析器库，例如 Jsoup。 https://jsoup.org/

此问题的答案中提供了操作方法： How to parse XML with jsoup

Answer 2

虽然奇怪，但这个 XML 实际上是格式正确的，可以用普通的 XML 工具解析。 TextWithNodes 元素只有混合内容。

TextWithNodes 的字符串值可以通过简单的 XPath 获得，

string(/TextWithNodes)

产生你想要的文本，没有其他标记（自关闭或其他）：

 A TEENAGER yesterday accused his parents of cruelty
by feeding him a daily diet of chips which sent his weight
ballooning to 22st at the age of l2.

Answer 3

下面是一些示例代码，使用在 Java 中使用 XPATH 的想法作为答案（感谢@kjhughes）：

public static void main(String[] args) throws IOException, ParserConfigurationException, SAXException, XPathExpressionException {

    String text = "<TextWithNodes>\n" +
            " <Node id=\"0\"/>A TEENAGER <Node\n" +
            "id=\"11\"/>yesterday<Node id=\"20\"/> accused his parents of cruelty\n" +
            "by feeding him a daily diet of chips which sent his weight\n" +
            "ballooning to 22st at the age of l2<Node id=\"146\"/>.<Node\n" +
            "id=\"147\"/>\n" +
            "</TextWithNodes>";
    DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = builderFactory.newDocumentBuilder();
    Document xmlDocument = builder.parse(new ByteArrayInputStream(text.getBytes("UTF-8")));
    XPath xPath = XPathFactory.newInstance().newXPath();
    String expression = "//TextWithNodes";
    System.out.println(xPath.compile(expression).evaluate(xmlDocument, XPathConstants.STRING));
}

打印出来：

A TEENAGER yesterday accused his parents of cruelty by feeding him a daily diet of chips which sent his weight ballooning to 22st at the age of l2.
