Hi

Given the following input (number of column elements is arbitrary);

<wrapper>
	<column>
		<price>111</price>
		<price>222</price>
		<price>333</price>
		<price>444</price>
		<price>555</price>
		<price>666</price>
		<price>777</price>
		<price>888</price>
		<price>999</price>
	</column>
	<column>
		<price>999</price>
		<price>888</price>
		<price>777</price>
		<price>666</price>
		<price>555</price>
		<price>444</price>
		<price>333</price>
		<price>222</price>
		<price>111</price>
	</column>
	<column>
		<price>555</price>
		<price>666</price>
		<price>777</price>
		<price>111</price>
		<price>222</price>
		<price>333</price>
		<price>444</price>
		<price>555</price>
		<price>666</price>
	</column>
</wrapper>

I need to identify the price element(s) with the lowest value within
certain position ranges.

So,	range1 --> Position() < 5
	range2 --> Position() >=5

		<price lowest="range2">111</price>

	<column>
		<price>555</price>
		<price>666</price>
		<price>777</price>
		<price lowest="range1">111</price>
		<price>222</price>
		<price>333</price>
		<price>444</price>
		<price>555</price>
		<price>666</price>
	</column>
</wrapper>

I am able to use XSLT 2. Could someone please point me in the right
direction?

Thanks.
