external default ns problem

[Jason Winshell <jw...@bearriver.com>]

Hi folks,

I having a problem getting Xalan to match input which explicitly is 
governed by a schema defined to be the default namespace.

test.xsd:
--------

<?xml version='1.0' encoding='UTF-8'?>
<xsd:schema

   xmlns:xsd="http://www.w3.org/2001/XMLSchema"
   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"

   targetNamespace="http://junk.com/Test"
>
<xsd:element name="test">
   <xsd:complexType>
     <xsd:sequence minOccurs="1" maxOccurs="unbounded">
       <xsd:element name="this" type="xsd:string"/>
     </xsd:sequence>
   </xsd:complexType>
</xsd:element>
</xsd:schema>

input.xml
---------

<?xml version='1.0' encoding='UTF-8' standalone="no" ?>
<test
   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"

   xmlns= "http://junk.com/Test"
   xsi:schemaLocation="http://junk.com/Test test.xsd"
>
   <this>
     thisdata
   </this>
</test>

XSL:

transform.xsl
-------------
<?xml version='1.0' encoding='UTF-8' standalone="no" ?>
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:xsd="http://www.w3.org/2001/XMLSchema"
>
   <xsl:output method = "xml" indent = "yes" />


   <!-- the root element is schema -->
   <xsl:template match="/">
     ## root was matched
     count this: <xsl:value-of select="count(//this)"/>
     <xsl:apply-templates select="*"/>
   </xsl:template>

   <xsl:template match="this" >
     elem name=<xsl:value-of select="name()"/>
     ## this was matched
     <xsl:apply-templates/>
   </xsl:template>
</xsl:stylesheet>

I've tried Xalan 1.2.2, 2.1.0, and 2.2.D14 all which produce
this result which does not match elements in the default
name space.
---------
<?xml version="1.0" encoding="UTF-8"?>
## root was matched
count this: 0

thisdata
------

The <this> element goes unmatched.

By replacing the use of:
   xmlns= "http://junk.com/Test"
   xsi:schemaLocation="http://junk.com/Test test.xsd"
With:
   xsi:noNamespaceLocation="test.xsd"

Things work as expected, producing the desired result:

<?xml version="1.0" encoding="UTF-8"?>

## root was matched
count this: 1

elem name=this
## this was matched

thisdata

Interestingly if I Turbo XML on this same input.xml
(which uses Xalan for XSLT) I get the correct result.

The problem goes away if input.xml uses a non-default namespace for 
all the elements to be matched (with associated namespace changes in 
transform)

input.xml:

<?xml version='1.0' encoding='UTF-8' standalone="no" ?>
<foo:test
   xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"

   xmlns:foo= "http://junk.com/Test"
   xsi:schemaLocation="http://junk.com/Test test.xsd"
>
   <foo:this>
     thisdata
   </foo:this>
</foo:test>

transform.xsl

<?xml version='1.0' encoding='UTF-8' standalone="no" ?>
<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:xsd="http://www.w3.org/2001/XMLSchema"

   xmlns:foo="http://junk.com/Test"

>
   <xsl:output method = "xml" indent = "yes" />


   <!-- the root element is schema -->
   <xsl:template match="/">
     ## root was matched
     count this: <xsl:value-of select="count(//foo:this)"/>
     <xsl:apply-templates select="*"/>
   </xsl:template>

   <xsl:template match="foo:this" >
     elem name=<xsl:value-of select="name()"/>
     ## this was matched
     <xsl:apply-templates/>
   </xsl:template>
</xsl:stylesheet>


Why is Xalan not matching elements when the input document has a 
default namespace that is explicitly declared (as opposed to using 
noNameSpaceLocation)?
