Re: [xsl] passing several external arguments to the spreadsheet

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Hi,

Another alternative is to use an external configuration file to store 
the list of languages as an XML document, and call that in from your 
main stylesheet using the document() function.

This is probably easier if your list of languages becomes long and/or 
you need to control it in some way (for example, validating it 
against a list of known languages).

Using a runtime parameter may be easier if you need control 
dynamically at runtime, you don't need the list to persist between 
runs, and your list is short.

The two approaches can also be combined. For example, your external 
list can control what languages are allowed, while the runtime 
parameter gives those that will actually be used (values in the 
parameter that don't appear in the external list can be ignored).

Finally, note that tokenize() is not available in unextended XSLT 
1.0. If you can't use XSLT 2.0 or a 1.0 extension function you'll 
need to work around this limitation.

Cheers,
Wendell
