[xsl] Copying and updating selectively

["John Reid" <John.Reid@xxxxxxxxxxxxxxx>]

g'day,

i got so far with this and then came up empty. I want to update/copy a
xml file updating any yes node to null (i guess deleting the text node
is the better way to put it). So that i start with ONE and end with TWO
on the condition that the @ID date is within the two date parameters.
The code at the bottom is my starting attempt. The two date parameters
are $varFrom=20030806 and $varTo=20030814

any thoughts

salud John Reid
