I have a document that has a doctype with public ID , system ID and an
internal subset of DTD.
When I do XLST translation with xml output and specify System ID and public
ID:
<xsl:output method="xml"
doctype-public="...."
doctype-system="...."
indent="no"
encoding="ISO-8859-1" />,
the internal subset of DTD is lost in the output document.
Is this expected behavior?
Yes.
Is there a way to keep the internal subset of DTD?
No. The internal declaration subset is considered an aspect of the syntax
of the input document, and it is not preserved in the data model for XPath
upon which XSLT operates. Therefore, there is no way to copy that
information to the result tree, which is also constructed using the data
model for XPath. Without representation in the data model, there is no way
your input can be preserved for the output.
You have two choices:
(1) - create a mini-DTD that contains your internal declaration subset plus
a parameter entity reference to your main DTD
- you can then point to the mini-DTD in your <xsl:output>, without an
internal declaration subset, and the resulting file will find those
declarations and the main body through the parameter entity reference
(2) - craft your own resulting internal declaration subset using a text
node and disable-output-escaping.
I hope this helps.
