Question

我的xml文档中有projectDetails节点，该节点是通过java jdom api创建的，而节点内部的数据来自数据库。
问题是描述字段以html的形式存储在数据库中。当我将其添加到<descriptionDetails />元素中，并使用Java的transform类对其进行转换时，它将转义所有html标记。
是否有可能像其余标签一样获取HTML代码作为descriptionDetails的子代并进行转义。

  <projectDetails label="label.projectDetails">
    <descriptionDetails label="label.descriptionDetails">
    &lt;html&gt;
 &lt;head&gt;&lt;/head&gt;

  &lt;/div&gt; 
  &lt;h1&gt;H1 heading&lt;/h1&gt;

 &lt;/body&gt;

您可以使用https://docs.oracle.com/javase/8/docs/api/javax/xml/transform/TransformerFactory.html#newTransformer-javax.xml.transform.Source-从样式表中创建一个，而不用newInstance().newTransformer()使用默认的Transformer

<xsl:stylesheet
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="descriptionDetails/text()">
      <xsl:value-of select="." disable-output-escaping="yes"/>
  </xsl:template>

</xsl:stylesheet>

但是请注意，您转义的HTML包含例如实体引用 ，该实体引用随后会将您的输出转换为格式不正确的XML，因为该实体未在XML中预定义。
