using document() function - first iteration is OK; second iteration is E

hi -

I am processing an input xml file (say input.xml) via (report.xsl) to 
generate a report.

report.xsl in turn loads another *xml file (schema.xml) through document() 
function so as to process the input.xml.  <schema.xml> contains some look-up 
information dictating how <input.xml> need to be processed.

Here is how I am referencing the "schema.xml" in the "report.xsl".

<xsl:variable name="schemaFile" select="document('schema.xml')"/>
<xsl:variable name="schemaRoot" select="$schemaFile/Schema"/>
<xsl:variable name="schemaList" select="$schemaRoot/SchemaFactors"/>

When I run the report first time (my appserver is weblogic 7.0), everything 
is working fine. I see the results I wanted.

However, when I run the report for the second time during the same session,  
I am getting  "schemaList" as empty.

The values of "schemaFIle" and "schemaRoot" appear to be correctly loaded in 
both the cases. The problem is with "schemaList" variable which is coming out 
empty during the second iteration.

can any of you please throw some pointers on why this is happening and how to 
resolve this?

thanks
