RE: [xsl] 2 Questions: (1) about looping for declaring table columns (2) variable table widths

["Gagan Bhalla" <gbhalla at mediaprise dot com>]

Thanks for all the helpful responses from all you guys. For my purposes, the
simple recursive algorithm would work fine for now and I intend to move to
the least recursive example given by Dmitro later on. But as was pointed out
by you all earlier, thie simple recursive example crashes. I tried the
example below and looks like my XSLT processor (Xalan) does not like a call
from the "table" template to the "toy-solution" template with a "index"
param being passed in like shown in the example given below by Jarno.
The exact error is:
XSLT Error (javax.xml.transform.TransformerConfigurationException):
xsl:with-param is not allowed in this position in the stylesheet!

Can you call a template by name with a param being passed in xalan? I have
tried many different ways for doing this and they all give me the same error
as above. Also, looked at
http://www.w3.org/TR/WD-xslt#section-Passing-Parameters-to-Templates  Some
of the calls I tried were:
	<xsl:call-template name ="tableColumn" />
		<xsl:with-param name="index" select="@cols" />
	</xsl:call-template>

	<xsl:call-template name ="tableColumn" />
		<xsl:with-param name="index">"@cols"</xsl:with-param>
  	</xsl:call-template>

	<xsl:apply-templates select ="tableColumn" />
		<xsl:with-param name="index" select="@cols" />
	</xsl:apply-templates>

Looking at textbook examples, looks like either of these call should be
valid. Is there some kind of configuration parameter that needs to be
changed in the xalan.jar to allow this call? Since our development effort
has been using Xalan so far, I would rather stick to that rather than change
to Saxon if possible?

Thanks for all your help,
