Subject Re: Problem evaluating xpath with muliple prefix with different namespace
Date Mon, 09 Jul 2007 16:04:59 GMT
Hi,

I found two problems in the stylesheet.

The first is with the following line:

<xsl:element name="buybiz:postBuy" namespace="{$bizServiceNameSpace}" 
xmlns:mod="{$intModelNameSpace}">

In the XSLT 1.0 Specification, 7.6.2 Attribute Value Templates (
http://www.w3.org/TR/xslt#attribute-value-templates) it says:

NOTE:Not all attributes are interpreted as attribute value templates. 
Attributes whose value is an expression or pattern, attributes of 
top-level elements and attributes that refer to named XSLT objects are not 
interpreted as attribute value templates. In addition, xmlns attributes 
are not interpreted as attribute value templates; it would not be 
conformant with the XML Namespaces Recommendation to do this. 

So xmlns:mod="{$intModelNameSpace}" is just treated as a string value and 
is not evaluated as an AVT.

Since there is a variable declaration: <xsl:variable 
name="intModelNameSpace">http://schemas.xxx.com/model</xsl:variable>, I 
tried replacing xmlns:mod="{$intModelNameSpace}" with 
xmlns:mod="http://schemas.xxx.com/model" but that did not work either 
because now in the stylesheet the prefix mod is bound to the namespace 
http://schemas.xxx.com/model, but in the xml input document the prefix mod 
is bound to http://ws.xxx.com/2007/06/model so there is no match.  So I 
tried just removing that namespace declaration so that:

    <xsl:element name="buybiz:postBuy" namespace="{$bizServiceNameSpace}" 
xmlns:mod="{$intModelNameSpace}">

becomes:

    <xsl:element name="buybiz:postBuy" namespace="{$bizServiceNameSpace}">

and then everything works.

If you need that namespace declaration for some reason (though it didn't 
look like it was being used) then you can do something like this:

    <xsl:element name="buybiz:postBuy" namespace="{$bizServiceNameSpace}" 
xmlns:mod="http://schemas.xxx.com/model" xmlns:modtarget="
http://ws.xxx.com/2007/06/model">

    ...

    <xsl:with-param name="cat" 
select="serviceBusMessage/payload/buytypes:postLiveBuyRequest/buytypes:liveBuy/buytypes:category/modtarget:catName"/>

    ....

    <xsl:with-param name="subcat" 
select="serviceBusMessage/payload/buytypes:postLiveBuyRequest/buytypes:liveBuy/buytypes:category/modtarget:subCatName"/>


Note that the XSLT processor uses the namespace bound to the prefix to 
match nodes in the xml input document and not the prefix name itself.


Thanks.
