Re: [xsl] Creating unique groups

[Dave Roe <david_roe@xxxxxxx>]

Fantastic - that certainly does the trick, thank you.

Is there a way of extending this approach so that it can de-duplicate 
entries?

For example, if I have:

<root>

	<group name="group1">
		<entry name="entry1" />
		<entry name="entry2" />
	</group>

	<group name="group1">
		<entry name="entry2" />
		<entry name="entry3" />
	</group>

</root>

and I want to end up with:

<root>

	<group name="group1">
		<entry name="entry1" />
		<entry name="entry2" />
		<entry name="entry3" />
	</group>

</root>

(with producing 2 entries for entry2).

Thanks again,
/dave
