Re: [xsl] XSL sheet Optimisation

[David Carlisle <davidc at nag dot co dot uk>]

  Would it be better (faster) to create keys for all the sections and access
  the particular section with it's key:
  <xsl:apply-templates select="key('mykey', $id)"/>
  or would it be better to do something like:
  <xsl:apply-templates select="//*[@id=$id]"/>

It probably depends on how often you do that. In making the key table
then essentially the system has to traverse the document, so if you only
do it once, probably you don't save much time, and you have the cost
of building the table. But if you do a lot of these (even if only
processing one section, you might need to look up ids of the other
sectiosn for cross refs and links) then the key will start to win.
