[英]Parse XML Self-Closing Tags with Text
嘿大家我试图解析我的XML文件的这一部分。 我遇到的问题是文本包含很多自闭标签。 我无法删除这些标签,因为它们为我提供了一些索引细节。 如何在没有所有“Node”标签的情况下访问文本?
<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>
虽然奇怪,但这个XML实际上是格式良好的,可以使用普通的XML工具进行解析。 TextWithNodes
元素只是混合内容。
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(自我关闭或其他):
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.
下面是一些示例代码,使用Java中的XPATH回答https://stackoverflow.com/a/49926918/2735286(@kjhughes的信用):
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:
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.
使用XML解析器库,如Jsoup。 https://jsoup.org/
