[xsl] XPath perfomance in attributes or nodes?

[Arjé Cahn <Arje at hippo dot nl>]

Hi everyone,

Does anyone have some solid performance figures on using XPath on attributes or nodes?

For example, I have the following XML snippet:

	<projects>
		<project uid="{6A97F258-93A7-4C5E-B712-052130A5208C}">
			<uid>{6A97F258-93A7-4C5E-B712-052130A5208C}</uid>
			<name>The project</name>
			<description>This is the project</description>
			<startdate>01-01-2002</startdate>
		</project>
		<project uid="{6A97F258-93A7-4C5E-B712-052130A5208D}">
			<uid>{6A97F258-93A7-4C5E-B712-052130A5208D}</uid>
			<name>Another project</name>
			<description>This is another project</description>
			<startdate>02-02-2002</startdate>
		</project>
	</projects>

And I want to select a <project>.
Is it faster using XPath
	projects/project[uid='{6A97F258-93A7-4C5E-B712-052130A5208C}']
or
	projects/project[@uid='{6A97F258-93A7-4C5E-B712-052130A5208C}']
or even (but this is not always possible)
	projects/project[name='The project']
???

I will have about 10000+ items.

Arjé Cahn
