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)...

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

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