Hi Andrew,

Yes, the variable $node gets set with:

>   <xsl:variable name="node" select="node[@order = $from]" />

This gets the node element child of the current element (whatever the
current element was when the template was originally called) whose
order attribute equals the value of the $from parameter that's been
passed into the template. So a different node each time the template
is called (recursively). If there isn't a node whose order attribute
is equal to the $from parameter, then the $node variable is an empty
set.

Cheers,

Jeni
