[xsl] SOLUTION: namespaces issue

["Snow, Corey" <csnow at deltadentalwa dot com>]

A while back, I posted a question regarding getting fully
namespace-qualified XML out of content that was escaped. I received a couple
of responses, for which I am very grateful.

The suggestions I received were to use the XSL functions such as
substring-before, replace() and substring-after to search for instances of a
given namespace declaration, then put the appropriate "xmns" attribute at
that point. This was problematic in cases such as:

<elementname xlink:type="simple" xlink:href="target.html"/>

For which I needed to obtain:

<elementname xmns:xlink="http://www.w3.org/1999/xlink"; xlink:type="simple"
xlink:href="target.html"/>

I couldn't do a simple search/replace on something like this or I'd end up
with multiple xmlns: attributes. A more complex search/replace template
using XSL was doable, but I settled on using an extension function. I
decided that since I was already in for a penny in terms of portability, I'd
go for the pound as well. When I start receiving well-formed XML from this
system in future versions I can get rid of all this jiggery-pokery to get
the stuff working.

At any rate, I wrote an extension function in VBScript, viz:

<msxsl:script language="VBScript" implements-prefix="wds">
<![CDATA[
	Function ConvertSerializedXMLToNodeList(strXML)
		Dim objXML
		Dim objDocFragment
		Dim objChild
		Set objXML=CreateObject("MSXML2.DOMDocument.4.0")
		objXML.async=False
		If Not objXML.loadXML("<root
xmlns:xlink='http://www.w3.org/1999/xlink'>" & strXML & "</root>") Then
			ConvertSerializedXMLToNodeList="Error: " &
objXML.parseError.reason
		Else
			Set objDocFragment=objXML.createDocumentFragment
			For Each objChild in
objXML.documentElement.childNodes
				objDocFragment.appendChild objChild
			Next
			ConvertSerializedXMLToNodeList=objDocFragment.xml
		End if
		Set objXML=Nothing
		Set objDocFragment=Nothing
	End Function
]]>
</msxsl:script>

and to get the appropriately-escaped XML, I do the following:

	<xsl:element name="content">
		<xsl:value-of
select="wds:ConvertSerializedXMLToNodeList(string($serialized-xml))"
disable-output-escaping="yes"/>
	</xsl:element>

Where $serialized-xml is the escaped XML, obviously. This is about the
ugliest hack I've ever had to do, but it works and I'm satisfied with that
for now. At least when this transformation process is done, I've got nicely
formed XML.

Thanks for the responses on my original question,

Corey Snow
