xsl schema and Namespaces issue

[william_hulse@hotmail.com]

The general process i am currently working on is this:


STEP 1 xml doc1 is transformed using stylesheet1 to produce xml doc2

- xml doc1 has a namespace declaration as follows...

<?xml version="1.0" encoding="iso-8859-1" standalone="yes "?>
<?xml-stylesheet type="text/xsl"
href="G:\Workin g\User\Will_Hul se\NEW\xmldb\co de\Bank_Stateme nts_Schema\EXBA EUFRED01.xsl"?>
<FILE>
<GENERAL>
......

</FILE>


- stylesheet1 has namespace declaration as follows

<?xml version="1.0"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output indent="yes"/>

....

</xsl:stylesheet>

- the result has namespace as follows


<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl"
href="G:\Workin g\User\Will_Hul se\NEW\xmldb\co de\Bank_Stateme nts_Schema\EXBA EUFRED02.xsl"?>
<FILE>
<GENERAL>
....

</file>

.... which is fine

STEP 2 - xml doc2 is transformed using stylesheet2 to produce xml doc3
which must conform to an xml schema

- xml doc2 has namespace as follows

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl"
href="G:\Workin g\User\Will_Hul se\NEW\xmldb\co de\Bank_Stateme nts_Schema\EXBA EUFRED02.xsl"?>
<FILE>
<GENERAL>
....

</file>


- stylesheet2 has namespace declaration as follows

?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" omit-xml-declaration="no " indent="yes"/>

- but also has the following clause to insert namespace info into
resulting document, 'linking' it to a schema bank_stat.xsd

<FILE xmlns="http://www.oracle.com/bank_stat.xsd"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocat ion="http://www.oracle.com/bank_stat.xsd
G:\Working\User \Will_Hulse\NEW \xmldb\code\Ban k_Statements_Sc hema\BANK_STAT. xsd">
<xsl:apply-templates select="BANK_ST ATEMENTS"/>
</FILE>



The result however contains the following with a bogus empty namespace
declaration in BANK_STATEMENTS

<?xml version="1.0" encoding="UTF-8"?>
<FILE xmlns="http://www.oracle.com/bank_stat.xsd"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocat ion="http://www.oracle.com/bank_stat.xsd
G:\Working\User \Will_Hulse\NEW \xmldb\code\Ban k_Statements_Sc hema\BANK_STAT. xsd">
<BANK_STATEMENT S xmlns="">
<GENERAL>
<FILENAME>EUBAE UFRED01.XML</FILENAME>
.....



-- the namespace of the schema is as follows

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.oracle.com/bank_stat.xsd"
xmlns:xdb="http ://xmlns.oracle.co m/xdb"
targetNamespace ="http://www.oracle.com/bank_stat.xsd"
elementFormDefa ult="qualified" attributeFormDe fault="unqualif ied">
<xs:element name="FILE">
<xs:complexType >



Questions..

- Why does the bank statements tag contain xmlns="" and how can we stop
it happening?

- Is there a better way to insert schema referencing into the result of
an xsl transform?

- How does the schema namespace attributes elementFormDefa ult and
attributeFormDe fault play a part in this...
making the value of elementFormDefa ult = "unqualifie d" in the schema
makes the xml fail validation. If we
then remove the bogus xmlns="" from the doc, it then passes
validation..


Any help with the above would be greatly appreciated...

I don't see namespace declaration here, neither... plus the
<FILE>...</file> is not well-formed.

Man, where do you see those namespace declarations!?

Where's the "clause" to insert that (following) namespace info?

I didn't see any default namespace declarations in your stylesheets
(or in what you've shown), but then it shouldn't need to output a
default nonamespace declaration if it is the root of your document,
I think.

You didn't show how do you do it, currently.

Too many questions - define more precise issues/topics and post
questions separately. Post or preferably point URLs to complete
examples you're trying with and which demonstrate your problem.

Re: xsl schema and Namespaces issue

Apologies for some of this i was in a rush to get out of the office...

Anyway some additional info..

We can ignore STEP 1 as it works fine

STEP 2 The xml is then transformed using a second xsl to produce a
final xml
which must conform to an xml schema

- xml has no explicit namespace declaration as follows..

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl"
href="G:\Workin g\User\Will_Hul se\NEW\xmldb\co de\Bank_Stateme nts_Schema\EXB AEUFRED02.xsl"? >

<FILE>
<GENERAL>
....
</FILE>

- stylesheet2 has again standard xsl namespace declaration as follows

?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:styleshe et
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"versi on="1.0">
<xsl:output method="xml" omit-xml-declaration="no " indent="yes"/>

- but also contains the following fragment to create a FILE element
that includes namespace info, 'linking' it to a schema bank_stat.xsd

<FILE xmlns="http://www.oracle.com/bank_stat.xsd"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"xsi:sc hemaLocation="h ttp://www.oracle.com/bank_stat.xsd

G:\Working\User \Will_Hulse\NEW \xmldb\code\Ban k_Statements_Sc hema\BANK_STAT .xsd">

<xsl:apply-templates select="BANK_ST ATEMENTS"/>
</FILE>

- The result from the above transformation however contains the
following fragment with a bogus empty namespace declaration ie
<BANK_STATEMENT S xmlns="">

<?xml version="1.0" encoding="UTF-8"?>
<FILE xmlns="http://www.oracle.com/bank_stat.xsd"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"xsi:sc hemaLocation="h ttp://www.oracle.com/bank_stat.xsd

G:\Working\User \Will_Hulse\NEW \xmldb\code\Ban k_Statements_Sc hema\BANK_STAT .xsd">

<BANK_STATEMENT S xmlns="">
<GENERAL>
<FILENAME>EUBAE UFRED01.XML</FILENAME>
.....

- the namespace declaration of the schema the above xml has to conform
to is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.oracle.com/bank_stat.xsd"
xmlns:xdb="http ://xmlns.oracle.co m/xdb"targetNames pace="http://www.oracle.com/bank_stat.xsd"

elementFormDefa ult="qualified" attributeFormDe fault="unquali fied">
<xs:element name="FILE">
<xs:complexType >

Questions..


1 - Why does the bank statements tag contain xmlns="" and how can we
stop it happening?
2 - Is there a better way to insert schema referencing into the result
of an xsl transform?
3 - How does the schema namespace attributes elementFormDefa ult and
attributeFormDe fault play a part in this...
making the value of elementFormDefa ult = "unqualifie d" in the schema
makes the xml fail validation. If we
then remove the bogus xmlns="" from the doc, it then passes
validation..


Any help with the above would be greatly appreciated...

Again, it is hard to guess from the partial messy sources you're
posting - next time just put complete examples (which need not to be
the originals if they contain sensitive information), which
demonstrate your problem, on the web and point to them. Either way
you're throwing away your chances somebody would have a look at your
problem.

Anyway, probably the "BANK_STATEMENT S" element is not descendant of
the "FILE" element (where you declare the default namespace) in the
stylesheet, so it effectively doesn't have a namespace - that's why
the generated xmlns="" appears (because in the generated structure
the "BANK_STATEMENT S" is descendant of the "FILE"). You should
declare the default namespace at the root stylesheet element:

<xsl:styleshe et version="1.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
xmlns="http://www.oracle.com/bank_stat.xsd">
...
</xsl:stylesheet>
