RE: [xsl] Passing a variable number of parameters or rather an array

Also a good idea, but do I have to go and save the xml as a file, is there
no way of passing in the it in also as a parameter, performance is not a
huge issue, but I wouldn't mind saving a bit of disk latency.

More importantly how do I do array/string[1] in some sort of loop, sorry I
am very new to xslt.

thanks

The details of how to pass stylesheet parameters to a transformer is
specific to the particular XSLT processor.

But there is a portable (*) way of doing what you want to do:

Create your array as an xml document: e,g.:

<array>
 <string>string one</string>
 <string>string two</string>
</array>

Then pass the URI of this document as a string-valued parameter, and
use the document() function to access the array.

Now you can use XPath expressions such as array/string[1] to get the
first string-value from this document.

(*) assuming that all XSLT processors allow you to pass a
string-constant as a parameter.
