RE: Putting parameter into XPATH expression

Remove the apostrophes around the arguments.

So that, instead of this:
<xsl:with-param name="Position" select="'2'"/>

You have this:
<xsl:with-param name="Position" select="2"/>

You want to pass a number, but you're passing a string instead. That's why
+0 worked--it automatically converted the string to a number.

b['2'] or b['anyString'] will always return true; it won't give you a
positional predicate.

Instead, you want b[2]

Hope this helps,
