RE: how to pass parameters down through nested templat

Wendel

Fixed it :).
Thanks for your help.
Wierdly some places {} are required and some places they are not.
Is there some kind of ruleset or guideline on that ??

Here is the working XSL that should show anyone how to keep pushing
parameters as and when required in nested template calls or apply
templates

Subject: RE:  how to pass parameters down through nested templates
using xsl:apply templates in a nested fashion?

Wendell,

Just made the changes you suggested. But still have an issue.
Please correct the following if they are wrong.

To push the initial value of the parameter - (Okay or not)
<xsl:with-param name="HeadAlign" select="'Center'"/>
<xsl:with-param name="DataAlign" select="'Left'"/>

To obtain the parameter value in the called template  (with default
values)
<xsl:param name="HeadAlign" select="'Right'"/>

Its just a literal string that I want to place in the <th>, <td> or <tr>
tags to set the text alignment of the cell. Like this... (doesn't work)
To push the value of the parameter out.
(Should I use XSL"value of and how would I actually write it into the
the following HTML tags ??

	<tr align="$HeadAlign">
	<th align="$HeadAlign">
	<td align="$DataAlign">

Unfortunately it wont "spit" out those parameters into the th, tr, td
values. I have tried this with curly braces and without and etc.

Of course I am getting nowhere with the trial and error.

Please let me know what would be the correct "syntax" for the THREE XSL
statements as mentioned above. (to make this possible :( ).

Thanks a lot.
