[Enhancement] XSL Taglib

[Luca Orlandi <lu...@inferentia.it>]

I've greatly appreciated the xsl taglib (I've developed myself something
similar using a simple servlet hierarchy ) and I would like to enhance it
introducing the support for parametric xsl.
I'm in doubt about the best interface for it:

<xsl:apply ...>
	<xsl:params>
		<param name="xxx">value1</param>
		...
	</xsl:params>
</xsl:apply>

This could be a solution but somehow collides with the "nested xml" syntax:

<xsl:apply xsl="/xml/employeeList.xsl">
<?xml version="1.0" encoding="ISO-8859-1"?>
<employees>
  <employee id="123">
    <first-name>John</first-name>
    <last-name>Doe</last-name>
    <telephone>800-555-1212</telephone>
  </employee>
</employees>
</xsl:apply>

So a better solution could be forcing the uso of a "parameter bean"

<xsl:params name="mypar">
	<param name="xxx">value1</param>
	...
</xsl:params>

Tha bean can then countain a hash of params to be used prior to process-ing
the XSL+XML.

Any suggestions?

Hi Luca,

I run into the same problem some while ago. I
ended up by implementing a "param" tag and I
sent it to this list. May be I should of sent/put
it somewhere else, I don't know.

A few other people asked about a mechanism to
pass parameters to the XSLT processor, but I
have no idea if the commiters are working/
considering this. Some feedback would be great.

Regards,
Marius

PS I sent you directly the source code and the 
original message regarding my "param" tag.

I guess I'd go with the some variation of the second so you can reuse
the concept in other tags later on.

BTW, I am assuming your second looks like:

 <util:params name="...">
   <util:param> ...
 </util:params>

with "util:param" instead of "param"

or maybe even
 <util:params name="....">
   <util:param name="xxx" value="...."/>
   <....
 </util:params>

Some of the core tags use your 1st approach, but we didn't want to add
any more concepts to the core tags in 1.{0,1,2} and instead left new
concepts for futher experimentation elsewhere.
