Unless you are doing a xsl:value-of (or a few other things), you are 
getting back nodes from xpath expressions.
You can call /my/path/to/node/text() to get the actual value in xpath 
format.

You can also do <xsl:value-of select="sum(/my/path/to/number)"/>
To return the sum off all numbers in the 'number' nodes.
