This is a common situation.  While you are within the for-each block,
the context comes from the external document, so path expressions refer
to it, not to the original source document.  The solution is to create a
global variable for the source document, like this -

<xsl:variable name='source-doc' select='/'/>

You can use this variable, which contains all the nodes from the source
document, within the for-each loop.  Note that you may want to be more
specific than "/", depending on your needs.
