Re: Variable Array extract

Actually, the monthnames element cannot have a null namespace URI.  From
section 2.2:

   http://www.w3.org/TR/xslt#stylesheet-element

   "In addition, the xsl:stylesheet element may contain any element not
   from the XSLT namespace, provided that the expanded-name of the element
   has a non-null namespace URI."

So:

   <?xml version="1.0"?>
   <xsl:stylesheet
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
     version="1.0"
     xmlns:foo="http://foo.com"
     exclude-result-prefixes="foo">

   <foo:monthnames>
     <month number="1">January</month>
     <month number="2">Febuary</month>
     <month number="3">March</month>
     <month number="4">April</month>
     <month number="5">May</month>
     <month number="6">June</month>
     <month number="7">July</month>
     <month number="8">August</month>
     <month number="9">September</month>
     <month number="10">October</month>
     <month number="11">November</month>
     <month number="12">December</month>
   </foo:monthnames>

   <xsl:template match="/">
     <out>
       <xsl:value-of select="document('')/xsl:stylesheet/foo:monthnames"/>
     </out>
   </xsl:template>

   </xsl:stylesheet>

Your variable is a result tree fragment, a type of object that is like a
node-set but upon which you can only perform string operations. You can
convert it to a node-set with the exsl:node-set($monthnames) extension
function or your XSLT processor's equivalent, if it doesn't support EXSLT.

A more portable way is to not use xsl:variable and just embed the lookup
data
in the stylesheet. Put this at the top level of the stylesheet (before the
first template, typically)...

  <monthnames>
    <month number="1">January</month>
    ...
  </monthnames>

...and then access it as a true node-set:

  document('')/xsl:stylesheet/monthnames
