Java 如何解析CDATA部分中带有HTML标记的XML文件？ Testcase:inittestreport]]> 58.675124设置温度设置为23设置温度=23]>

我有一个由工具以上述格式生成的.XML文件，其中包含CDATA部分中的html数据。使用java可以使用哪种解析器或以何种方式从XML文件中检索html数据？

只需将CDATA作为文本内容访问即可

变量1（DOM）： 使用/path/toYour/sample/file.xml

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;

import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamConstants;
import javax.xml.stream.XMLStreamReader;

public void getCDATAFromHardcodedPathWithStax() {
    String yourSampleFile = "/path/toYour/sample/file.xml";
    String cdataNode = "extendedinfo";
    XMLStreamReader r = null;
    try (InputStream in =
            new BufferedInputStream(new FileInputStream(yourSampleFile));)        {
        XMLInputFactory factory = XMLInputFactory.newInstance();
        r = factory.createXMLStreamReader(in);
        while (r.hasNext()) {
            switch (r.getEventType()) {
            case XMLStreamConstants.START_ELEMENT:
                if (cdataNode.equals(r.getName().getLocalPart())) {
                    System.out.println(r.getElementText());
                }
                break;
            default:
                break;
            }
            r.next();
        }
    } catch (Exception e) {
        throw new RuntimeException(e);
    } finally {
        if (r != null) {
            try {
                r.close();
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
    }
}

Testcase:inittestreport]]>

它会给你

这里给出了一个使用JAXB的有趣替代方案：

下面给出了一个如何提取所有CDATA的示例：

看看下次提供的所有xml结构，我们就可以为您编写代码了。@SauliusNext文件类似于许多表数据，持续1k行，因此认为这可能是对stax的足够更改，它更适合大文件读取，这是答案：）我添加了第二个stax变体，虽然问题是关于一个包含1k行xml的小文件。我在SO中的第一个答案之一，希望在接受的答案中添加代码可以吗？
