Re: [xsl] Generating IDs and seperating elements

["Charles White" <chuck@xxxxxxxxxxx>]

Hi Jinesh:

You have a couple things going on here with the structure of your XSLT.
First, you didn't declare your parameters anywhere, at least not in the code
you provided here.

So, in answer to ######2,  the first part of your author template should
look like this:
<xsl:template match="author">
<xsl:param name="temppubid" />
<xsl:param name="tempperid">
<xsl:call-template name="generate-author-id"/>

It seems you were trying to call the template named generate-author-id,
which is defined elsewhere, but you used the xsl:template element to attempt
to do so, so I changed this:
 <xsl:template name="generate-author-id">
to this
<xsl:call-template name="generate-author-id"/>
in the code above (but not in the originally defined template named
generate-author-id that you built later in the stylesheet).

#####3: You took a sort of object-oriented developer's approach to
concatenation and mistakenly used the plus (+) operator in the concat
function, where as you should use commas instead:

concat('800000000',$last+$this)

becomes

select="concat('800000000',$last, $this)"

I'm not sure what you are asking about with ####1, so I'll let someone else
take over there. :-)
