Re: doctype?

[Michael Glavassevich-3]

Benson,

I expect the response that you would get from the Xalan folks is that the DOCTYPE isn't part of the data model [1][2] so doesn't appear in the result of the transform. I understand that the identity transformer is supposed to behave like following stylesheet snippet:

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

and that only includes nodes in the XPath data model. I think some folks believe the JAXP equivalent should copy everything, not just what's representable in the data model, but apparently Xalan and perhaps other XSLT processors do not do that.

You could try another API like the LSSerializer [3] which will serialize the full content of the DOM.

Thanks.

Thanks. LSSerializer did the job. I don't like doctypes, but I'm stuck with some.

You can set a DOCTYPE from XSLT using xsl:output/@doctype-system and
xsl:output/@doctype-public:

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

  <xsl:output doctype-public="eins zwei drei"
    doctype-system="http://eins.de/zwei/drei"/>

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

A DOCTYPE can be specified programmatically [1][2][3], so you don't need to write a stylesheet. Note that either approach only works if the DocumentType node has no internal subset. If it has one it will still be lost if you do this.

Thanks.

True, thanks. But I assumed the OP had already written one, as he wrote:

I might be wrong, but the first of the three references you gave is
probably not related to specifying the DOCTYPE.

Good catch. I meant to post a link to setOutputProperty():
