Re: Why does Doctype change processing of a document |
Hi,
With the DOCTYPE declaration the default
namespace gets set to "http://www.w3.org/1999/xhtml" so <xsl:template
match="html"> does not
match the html node because they are in different namespaces. The
test="name(child::node())='html'"
passes because there is no namespace prefix so the result of name() is
still 'html'.
From the xhtml1-strict.dtd:
<!--================ Document Structure
==================================-->
<!-- the namespace URI designates the
document profile -->
<!ELEMENT html (head, body)>
<!ATTLIST html
%i18n;
id ID
#IMPLIED
xmlns %URI;
#FIXED 'http://www.w3.org/1999/xhtml'
>
To handle input documents with the DOCTYPE
declaration you can add the following namespace declaration to your stylesheet:
xmlns:xhtml="http://www.w3.org/1999/xhtml"
and change your templates to use the
prefix, such as:
<xsl:template match="xhtml:html">
If you want to be able to handle input
documents with or without the DOCTYPE declaration then you would need to
do something like this:
<xsl:template match="*[local-name()='html']">
Thanks.

I', processing the document below with Xalan and the
template below
experience a funny effect that I cannot explain.
As long as I have the <!DOCTYPE-element in my document, processing will
correctly go as far as
> <xsl:template match="/">
>> <xsl:choose>
>>
<xsl:when test="name(child::node())='html'">
>> <xsl:apply-templates/>
>>
</xsl:when>
but then apply templates will ignore the correct template
> <xsl:template match="html">
and jump to the default template right at the bottom
<xsl:template match="@*|*|text()|processing-instruction()|comment()">
and mess up the transformation.
As soon as I remove the <!DOCTYPE-element everything works just fine.
Can anybody tell me what I'm missing here?
Thanks,
Ferdinand
