Using the equivalent of your code, it works for me. You have a problem
somewhere else in your stylesheet. Post your XML and XSLT and we can work
from there.

Nate-
Tried it....did'nt work. Tried assigning carid to a variable and sending
carid as is and it did not work.

Akila -
I copied XSL-List on this. If you have any other questions, feel free to
post them there (after you have searched the archives/faq of course). It
is
a great community of very intelligent people that can answer any XSLT
question you may have much clearer than I can. :) (You can get more
information about the list and subscribe to it at

There are a couple of things wrong with this. For starters, xsl:value-of
outputs whatever it selects to the result tree. In this case, you're
selecting $carId which doesn't have a value from what I can see. I guess
it's possible that it is a global variable. If you want to create a new
variable, do something like this:
<xsl:variable name="carId" select="."/>
Selecting . selects the context node, which in this case is the node that
matched the template. In this case, creating a variable is not necessary
though. If you change the call to look like this, it should do what you
want:
<xsl:call-template name="append-pad">
<xsl:with-param name="padChar" select = "' '"/>
<xsl:with-param name="padVar" select = "."/>
<xsl:with-param name="length" select = "'10'"/>
</xsl:call-template>
Also, you can search the archives to find post by Dimitre Novatchev
regarding his Divide and Conquer method of padding and/or visit exslt.org
for their method.
I'd also highly recommend that you pick up a good book if you can. Michael
Kay's /XSLT Programmer's Reference/
(
http://www.amazon.com/exec/obidos/ASIN/1861005067/qid=1022078929/sr=1-3/ref
=sr_1_3/102-3714411-3675320) is a great book, and Jeni Tennison's
/Beginning
XSLT/
(
http://www.amazon.com/exec/obidos/ASIN/1861005946/qid%3D/102-3714411-367532
0) promises to be great. (Anyone read it yet?)
HTH,
Nate

How should I modify the code if I were to call the append-pad passing the
attribute as the string ?

I saw this code example in your FAQ for padding in XSL
<xsl:template name="append-pad">
<!-- recursive template to left justify and append -->
<!-- the value with whatever padChar is passed in -->
<xsl:param name="padChar"> </xsl:param>
<xsl:param name="padVar"/>
<xsl:param name="length"/>
<xsl:choose>
<xsl:when test="string-length($padVar) < $length">
<xsl:call-template name="append-pad">
<xsl:with-param name="padChar" select="$padChar"/>
<xsl:with-param name="padVar" select="concat($padVar,$padChar)"/>
<xsl:with-param name="length" select="$length"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="substring($padVar,1,$length)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I called this function from my code base like this. I am trying to make
carId a fixed text of length 10 and want to append spaces to the right if
the length is <10.
<xsl:template match = "/ceo_di_msg/car_msg/carid">
<xsl:value-of select = "$carId"/>
<xsl:call-template name="append-pad">
<xsl:with-param name="padChar" select = "' '"/>
<xsl:with-param name="padVar" select = "$carId"/>
<xsl:with-param name="length" select = "'10'"/>
</xsl:call-template>
<xsl:text>*</xsl:text>
</xsl:template>
Why is it not working? What is wrong with the template call?
Thanks,
