Subject: Re: [xsl] Removing namespaces without escaping CDATA??? From: "Mukul Gandhi" <gandhi.mukul@xxxxxxxxx> Date: Mon, 9 Apr 2007 23:03:27 +0530 |
Let's say we have following XML: <x> <y></y> <p> <y></y> <q> <y></y> </q> </p> </x> (text content can be placed anywhere as desired)
If I do, <xsl:output cdata-section-elements="y" />, then all y elements will contain CDATA sections. This may be desirable in very specific cases. But it will be more convenient, if I am able to put CDATA section at this location /x/p/q/y, and not to any other y's.
>> Also, specifying cdata-section-elements here, <xsl:output >> cdata-section-elements="qnames" /> seem to have a shortcoming, that >> it's too global (as I said earlier). Do you agree to this point?
You can 'annotate' the result tree in XSLT 2.0, though possibly not as conveniently as Mukul Gandhi requests. The attribute 'cdata-section-elements' is an AVT in the xsl:result-document element and it must result in one or more qnames. But this requires redesigning your stylesheets in such a way that you use xsl:result-document, instead of xsl:output (but that should not be too hard if it is 'global'). This:
<xsl:variable name="my-cdata" select="'as-cdata'" /> <xsl:result-document cdata-section-elements="{$my-cdata}" href="analyze.xml"> <as-cdata> <xsl:text>Has some text</xsl:text> <not-cdata /> </as-cdata> <as-cdata>Less then is: <, ampersand is: &</as-cdata> </xsl:result-document>
results in the following output (Saxon 8.9):
<as-cdata><![CDATA[Has some text]]><not-cdata/> </as-cdata> <as-cdata><![CDATA[Less then is: <, ampersand is: &]]></as-cdata>
You have all freedom, the only drawback compared to your d-o-e-like approach is that you will have to determine the contents of the AVT beforehand, instead of per element. But as Michael and David already pointed out, would you really want to do this?
Cheers, -- Abel
PS: it is probably better to declare $my-cdata as 'xs:Qname' or 'xs:Qname*'.
