用于使用JDOM2进行测试的代码:
import java.io.IOException;
import java.io.InputStream;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import org.jdom2.CDATA;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;
import org.jdom2.output.XMLOutputter;
import org.jdom2.transform.JDOMResult;
import org.jdom2.transform.JDOMSource;
import org.junit.Test;
public class CdataTransformationTest {
@Test
public void learning_cdataTransformationWithJdom() throws Exception {
Document xslt = loadResource("xslt/cdata-transformation.xslt");
Document source = new Document(new Element("content")
.addContent(new CDATA(">&< test")));
Document transformed = transform(source, xslt);
XMLOutputter outputter = new XMLOutputter();
System.out.println(outputter.outputString(transformed));
}
private static Document transform(Document sourceDoc, Document xsltDoc) throws TransformerException {
JDOMSource source = new JDOMSource(sourceDoc);
JDOMResult result = new JDOMResult();
Transformer transformer = TransformerFactory.newInstance()
.newTransformer(new JDOMSource(xsltDoc));
transformer.transform(source, result);
return result.getDocument();
}
private static Document loadResource(String resource) throws IOException, JDOMException {
ClassLoader classloader = Thread.currentThread().getContextClassLoader();
InputStream inputStream = classloader.getResourceAsStream(resource);
if (inputStream != null) {
try {
SAXBuilder builder = new SAXBuilder();
return builder.build(inputStream);
} finally {
inputStream.close();
}
} else {
return null;
}
}
}
使用的JDOM版本:
<dependency>
<groupId>org.jdom</groupId>
<artifactId>jdom2</artifactId>
<version>2.0.6</version>
</dependency>
使用的XSLT处理器:
<dependency>
<groupId>xalan</groupId>
<artifactId>xalan</artifactId>
<version>2.7.1</version>
</dependency>
我一直在寻找方法来做到这一点,最好的答案是说在CDATA中包装内容所需要的是在cdata-section-elements
属性中添加标记名称。我无法使用JDOM,而不能使用Free online XSL Transformer。我也尝试使用saxon而不是xalan,但结果相同。
为什么这不起作用?我在这里错过了什么/做错了什么? JDOM是否忽略cdata-section-elements
属性?
我也试过包装这样的内容:
<xsl:text disable-output-escaping="yes"><![CDATA[</xsl:text>
<xsl:value-of select="." />
<xsl:text disable-output-escaping="yes">]]></xsl:text>
但是这会在JDOM中产生不需要的结果,这使得它很难使用。设置outputer.getFormat().setIgnoreTrAXEscapingPIs(true);
时可见,使用漂亮格式时看起来很难看。
<?xml version="1.0" encoding="UTF-8"?>
<transformed>
<?javax.xml.transform.disable-output-escaping?>
<![CDATA[
<?javax.xml.transform.enable-output-escaping?>
>&< test
<?javax.xml.transform.disable-output-escaping?>
]]>
<?javax.xml.transform.enable-output-escaping?>
</transformed>
答案 0 :(得分:2)
您正在转换为JDOMResult
,即树形表示,而不是流或文件。像cdata-section-elements
这样的输出指令仅在XSLT处理器将结果序列化为流或文件时使用,而不是在内存中构建结果树时使用。所以我认为如果你想用cdata-section-elements
作为XSLT的结果来构造CDATA部分,你需要确保你写一个文件或流或至少一个StringWriter,然后你可以从该文件加载JDOM结果或流分别创建String。
将转换方法重写为:
private static Document transform(Document sourceDoc, Document xsltDoc) throws JDOMException, IOException, TransformerException {
StringWriter writer = new StringWriter();
JDOMSource source = new JDOMSource(sourceDoc);
Result result = new StreamResult(writer);
Transformer transformer = TransformerFactory.newInstance()
.newTransformer(new JDOMSource(xsltDoc));
transformer.transform(source, result);
SAXBuilder builder = new SAXBuilder();
return builder.build(new StringReader(writer.toString()));
}
答案 1 :(得分:0)
试试这个:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" cdata-section-elements="transformed" encoding="utf-8"/>
<xsl:template match="/content">
<transformed>
<xsl:value-of disable-output-escaping="yes" select="."/>
</transformed>
</xsl:template>
</xsl:stylesheet>
我使用了msxsl命令行工具,它工作正常!
