RE: Understanding xsl:key

>From Jeni's reply
When you define the key:

> <xsl:key name="test" match="title" use="name"/>

Then you are setting up a number of associations between 'title' nodes and
key values given to them through their 'name' child:

node		key value
title[1]	'Design Patterns'
title[2]	'Pattern Hatching'
title[3]	'Building Applications'

When you use:

  key('test', 'Pattern Hatching')

you are saying "What nodes within the 'test' key have the key value of
'Pattern Hatching'?"

So
<xsl:key name="test" match="title" use="substring-before(name, ' ')"/>
will create 
node		key value
title[1]	'Design'
title[2]	'Pattern'
title[3]	'Building'

I assume though I haven't tried it.
