Subject: [xsl] Getting unique items from elements|

I have the following snippet of XML: <books> <book> <category>Children</category> <category>English</category> <title>Mary Poppins</title> </book> <book> <category>Children</category> <category>Spanish</category> <title>Los Perdidos</title> </book> </books> Which I currently (and erroneously) transform using: <xsl:template match="/"> <xsl:for-each select="books/book/category"> <xsl:value-of select="."/>, </xsl:for-each> </xsl:template> The output as you would expect includes the category of "Children" twice. Is there a way in XSL to extract only the unique elements from <category>? Thank you!
