XSL Stylesheet and using a metadata file

Greetings,

I am using an XML document as metadata for defining the fields of the flat
files I am trying to generate.

I thought at one point this was working but something must have changed
because I am no longer getting the desired results and I need help getting
back on track.

In my metadata XML file I have the following sample:

<records>
	<type_AA0>
		<record>
			<field_no>1</field_no>
			<starting_position>1</starting_position>
			<length>3</length>
			<justification>L</justification>
			<content></content>
			<default_value>AA0</default_value>
			<data_type>text</data_type>
			<name>record_id</name>
		</record>
		<record>	
			<field_no>1</field_no>
			<starting_position>1</starting_position>
			<length>3</length>
			<justification>L</justification>
			<content></content>
			<default_value>xxx</default_value>
			<data_type>text</data_type>
			<name>record_id</name>
			<plan_id>abc</plan_id>
		</record>
	</type_AA0>
</records>

This gets loaded into my stylesheet with this command:

<xsl:variable name="field_definitions"
select="document('my_metadata.xml')/records"/>

Here is my template:

<xsl:template match="claim_file">

	<xsl:apply-templates select="$field_definitions/type_AA0/*[(plan_id
= current()/provider[1]/claim[1]/plan_id) or (not(plan_id) and
(not(field_no=../type_AA0/*[plan_id =
current()/provider[1]/claim[1]/plan_id]/field_no)))]">
		
			<xsl:sort select="field_no" order="ascending"
data-type="number"/>
		
			<xsl:with-param name="current_context" select="."/>
						
		</xsl:apply-templates>

</xsl:template>

<xsl:template match="record">
	
		<xsl:param name="current_context"/>

	<!-- The rest of this code isn't relevant to my problem 
		but eventually (after going through a padding template) the
value gets printed out 
		to the output document -->

</xsl:template>

Here is a sample of my input XML document :

<?xml version='1.0' encoding='UTF-8'?>
<claim_file>
   <process_date>2005-02-10T02:21:49</process_date>
   <provider>
      <provider_organization_name>Best Eye Care</provider_organization_name>
      <claim>
		<plan_id>abc</plan_id>
	</claim>
   </provider>
</claim_file>

What I want to happen is, I want the field record from the metadata that
corresponds to the plan_id for this file (all claims will have the same
plan_id so I just use the first claim of the first provider to determine
what the plan_id is).  If there is no plan_id in the metadata file that
matches the one for the source file then I want to use the default field
record.  That is, the one with no plan_id elements in it.

What I exepct from the above output is:

"abc"

What I get is:

"AA0abc"

My problem is that it is not excluding the 'default' field record from my
metadata file.  If I run this with a different plan_id in the source XML
file, such as "def" then it will produce:  "AA0".

So it ALWAYS includes the default field record and then it will select the
field record for that plan if it matches.  What I want is either or, never
both.  Does that make sense?

Thanks much in advance,
Jim Neff
