A variable's scope in XSLT is only the containing block/element. 
Therefore if you define a variable in an <xsl:if>, it is only in scope 
with that <xsl:if> block, which is why it's telling you that $filename 
is undefined when you try to reference it outside of the <xsl:if>. If 
you need to compute a variable based on some conditions, you would put 
the conditions within the <xsl:variable> definition block.

Your code could be put into a template with a parameter representing the 
language, and use the parameter to build your output directory, then 
call the template as many times as needed with the appropriate language 
parameter. Basic idea is to use a variable for this value, rather than 
rewriting the same code twice with only the path being different.

You can certainly set this up in a single XSLT using <xsl:apply 
templates> with appropriate @select and/or @mode values. You would then 
write templates that match what you want to process, pull out only the 
things you want, rename whatever you want, and redirect to the desired 
output file. Then it's just a question of applying those templates in 
the desired order.
