There may be another parent category where "Illness expenses" belongs
to, lets say "George". Then the output should be as follows:
02/10/2010;George:Illness expenses:Pharmacy;Test Pharmacy, Oakland;-19.1;

Thanks in advance,

The following seems to do what you want, note there is no explicit recursion, or parameters involved, applying-templates just takes care of everything just as easily following attribute references as walking the trr via child relationships:

<xsl:stylesheet version="2.0" xmlns:xsl="";>

<xsl:key name="c" match="Category" use="@ID"/>
<xsl:variable name="c" select="document('Categories.xml')"/>
<xsl:template match="Entry">
<xsl:value-of select="Date"/>
<xsl:apply-templates select="key('c',CategoryID,$c)"/>
<xsl:value-of select="Recipient"/>
<xsl:value-of select="Value"/>

<xsl:template match="Category">
 <xsl:apply-templates select="key('c',@ParentID,$c)"/>
 <xsl:value-of select="en"/>
