Re: Keys across multilple input files

Jeni,

You are 100% correct - as always:-)  Fixing the $documents variable definition 
worked!

Thank you.

Here are some interesting performance statistics using the XALAN processor. 
Processing time for one big XML document containing all CLASS elements is almost 
4 times faster than processing each XML Class file separately.

The best option would be to generate the keys for all CLASS elements in one big 
XML file in one XSL process and save them in a way that they could be accessed 
by another XSL process. I haven't figured out how to do this yet.

Performance


1.  All classes in a single XML file.  Stylesheet uses keys to search
class elements in the same file.

Processing time:  8,873 milliseconds

2.  Each class in a separate XML file.  Stylesheet uses document() function
to search the keys for CLASS elements in each XML class file.

Processing time:  27,709 milliseconds

3.  Each class in a separate XML file.  Style sheet uses document() function
to search the CLASS elements ine each XML class file.

Processing time:  34,818 milliseconds

	I think what you're missing is that this isn't equivalent to the select
	expression that I used in my example.  I used:
	
	<xsl:variable name="documents" select="document(/documents/doc/@href)" 
/>
	
	In this, $documents is assigned to *the result of the document() 
function
	being called on* the node list that holds the 'href' attributes of all 
the
	'doc' elements that are children of the 'documents' document element in 
the
	input XML.
	
	In yours, $documents is assigned to the node list that holds the 'href'
	attributes of all the 'doc' elements that are children of the 
'documents'
	document element in 'filelist.xml'.  You need to apply the document()
	function to that list, i.e.:
	
	<xsl:variable name="documents" 
	  select="document(document('filelist.xml')/documents/doc/@href)" />
	
	Try that and see if it works.  I'm sorry that I didn't explain this in
	detail first time round.
	
	Cheers,
