[xsl] Checking a parent's attribute

[Nicholas Orr <nick@xxxxxxxxxxx>]

G'day all,

I've got some xslt that used to do the following :

<xsl:for-each select="ExportEntries/ExportEntry/Field">

but I realised I need it to be conditional on an attribute of one of  
the parent nodes, so I ended up splitting it up into 3 lines instead :

<xsl:for-each select="ExportEntries">
	<xsl:if test="../Restore/@state = 'True'">
		<xsl:for-each select="ExportEntry/Field">

This works as I want, but to me it doesn't seem to be the best way.   
Is there a better way to do that kind of check?  I want to restrict  
it to the "ExportEntries" node first, as there are only a limited  
number of times that that node will exist, and the "Restore state"  
node is often there for other things, so I think I'm being more  
efficient doing it this way.  Am I doing this right?

Thanks,
Nick
