java - 使用 Xalan-J 的 xsl cdata-section-elements 输出属性

Question

我正在尝试使用 Xalan 2.7.1 在 XSLT 结果中输出 CDATA 部分。我已将此 XSL 应用于工具中的 XML，结果包含 CDATA。在下面的方法中，结果中没有 CDATA，并且不会引发异常。我觉得我在这里错过了一些东西。

test.xml

<?xml version="1.0" encoding="UTF-8"?>
<parentelem>
    <childelem>Test text</childelem>
</parentelem>

测试.xsl

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" cdata-section-elements="newchildelem" />
<xsl:template match="/">
<parentelem>
    <newchildelem><xsl:value-of select="/parentelem/childelem" /></newchildelem>
</parentelem>
</xsl:template>
</xsl:stylesheet>

    public static void main (String[] args){
    try {
        XMLStreamReader xmlReader = XMLInputFactory.newInstance().createXMLStreamReader(
            new FileReader("test.xml"));

        XMLStreamReader xslReader = XMLInputFactory.newInstance().createXMLStreamReader(
                new FileReader("test.xsl"));

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Source xslSource = new StAXSource(xslReader);
        Source xmlSource = new StAXSource(xmlReader);
        Transformer transf = transformerFactory.newTransformer(xslSource);

        StringWriter xmlString = new StringWriter();
        XMLStreamWriter xmlWriter = XMLOutputFactory.newInstance().createXMLStreamWriter(
                xmlString);

        Result transformedXml = new StAXResult(xmlWriter);
        transf.transform(xmlSource, transformedXml);

        xmlWriter.flush();
        System.out.println(xmlString.toString());
    } catch (Exception e) {
        e.printStackTrace();
    }
}
}

控制台输出

<?xml version="1.0" encoding="UTF-8"?><parentelem><newchildelem>Test text</newchildelem></parentelem>

Answer 1

您是说要将 CDATA 作为元素的一部分输出吗？

<newchildelem><xsl:value-of select="/parentelem/childelem" /></newchildelem>

与

<newchildelem><xsl:text>&lt;![CDATA[
</xsl:text><xsl:value-of select="/parentelem/childelem" /><xsl:text>]]&gt</xsl:text></newchildelem>

或其他形式，但省略转义字符

<newchildelem><![CDATA[Test text]]></newchildelem>

或者我可能误解了这个问题？
