Re: Extracting highest values within a range

This would be easier in xslt2 or with node-set extension or if you
just gave the range as numerical values rather than prefixed with
"Result" but anyway:


<x>

<params>
	<resultstocompare>
		<start>Result1</start>
		<end>Result3</end>
	</resultstocompare>
	<resultstocompare>
		<start>Result5</start>
		<end>Result6</end>
	</resultstocompare>
</params>

<wrapper>
	<column1>
		<name>Result1</name>
		<name>Result2</name>
		<name>Result3</name>
		<name>Result4</name>
		<name>Result5</name>
		<name>Result6</name>
	</column1>
	<column2>
		<amount>1000</amount>
		<amount>200</amount>
		<amount>3000</amount>
		<amount>40</amount>
		<amount>50</amount>
		<amount>11</amount>
	</column2>
	<column3>
		<amount>44</amount>
		<amount>800</amount>
		<amount>66</amount>
		<amount>120</amount>
		<amount>90</amount>
		<amount>101</amount>
	</column3>
	<column4>
		<amount>1000</amount>
		<amount>200</amount>
		<amount>3000</amount>
		<amount>40</amount>
		<amount>50</amount>
		<amount>11</amount>
	</column4>
	<column5>
		<amount>1000</amount>
		<amount>200</amount>
		<amount>3000</amount>
		<amount>40</amount>
		<amount>50</amount>
		<amount>11</amount>
	</column5>
</wrapper>

</x>
