RE: Putting parameter into XPATH expression

The simplest way is to make $position a number by writing

<xsl:with-param name="position" select="1"/>

instead of

<xsl:with-param name="position" select="'1'"/>

which makes it a string.

Or you could force it to a number: a/b[number($position)],

or use a boolean predicate: a/b[position()=$position]
