Re: Generating IDs and seperating elements

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. :-)

Subject: [xsl] Generating IDs and seperating elements


Hello people,
two unique problems:

My XML is
<publication pubid="0002">
<author>steve lawer</author>
........
<publication>


I want my new XML as:
<publication pubid="0002">
........
</publication>
<person perid="100000004"> <!-- new id generation -->
<personname>steve lawer</personname>
</person>
<pubper> <!-- publication-person intersection -->
<pubid>0002</pubid>
<perid>100000004</perid>
</pubper>

My XSL is:
<?xml version="1.0"?>

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 <xsl:output method="xml" indent="yes"/>

<xsl:template match="publication">

<publication>
<xsl:copy-of select="@*|*[not(self::author or
self::editor)]"/> <!-- this is just to cut the authors
element-->
</publication>

<xsl:if test="author=not(.=preceding::author|editor)"
<!-- this is so that we get unique authors and
editors: Please comment on this #####1-->
        <xsl:apply-templates select="author">
<xsl:with-param name="temppubid" select="@pubid" />
</xsl:apply-templates>
</xsl:if>
</xsl:template>

<xsl:template match="author">
 <person>
<xsl:attribute name="perid">
 <xsl:template name="generate-author-id"> <!--
generating ids -->
</xsl:attribute>
<personname>
<xsl:value-of select="."/>
</personname>
</person>
<pubper>
 <pubid>
       <xsl:value-of select="$temppubid"/><!-- Why is
this not printing the parameter that I am sending
#####2 -->
  </pubid>
   <perid>
         <xsl:value-of select="$tempperid"/> <!- I
want to print the id that I just created for person
over here. Why is this not printing....how to print
the value ####3-->
   </perid>
<persontype>1</persontype>
 </pubper>
</xsl:template>



 <xsl:template name="generate-author-id">
  <xsl:variable name="last"
select="number(preceding::author[(_at_)perid][1]/@perid)"/>
  <xsl:variable name="this"
select="count(preceding::author[not(@perid)])+1"/>
  <xsl:variable name="temp"
select="concat('800000000',$last+$this)" />
 <xsl:value-of
select="substring($temp,string-length($temp)-9)" />
<!-- we just want 10-digit IDs -->
<xsl:template>

</xsl:stylesheet>




Please comment on ###1, ###2, ###3

appreciated

Thanks in advance
