get HTML or XHTML text in Value of xml element

I have projectDetails node in my xml document, which is created from java jdom api, and the data inside nodes comes from database.
Problem is with description field which is stored as html inside database.And when I am adding this into <descriptionDetails /> element, and transforming it using Java's transform class it is escaping all the html tags.
Is it possible to get Html code like rest of the tags as child of descriptionDetails and unescaped.

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

Solution

  • Instead of using the default Transformer with newInstance().newTransformer() you could create with https://docs.oracle.com/javase/8/docs/api/javax/xml/transform/TransformerFactory.html#newTransformer-javax.xml.transform.Source- one from a stylesheet like

    <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>

    used as the Source.

    Note however that your escaped HTML contains for instance an entity reference &nbsp; which would then turn your output into something that is not well-formed XML, as that entity is not predefined in XML.
