Re: Re: [xsl] Remove Duplicates from Recursive Template Calls

      <xsl:for-each select="//component/@id[.=$idRef]//..">

It must locate the component that is being referenced, recurse into that
component to follow the componentReferences to other components.  It must
recurse until there are no more componentReferences found.

>that's a very odd XPath. selecting the parent of every node below $idRef.

This locates the component that the componentReference refers.  The "//.." was
a typo.  It should be "/..".  I took the extra slash out of the code and ran
it again and the results are the same.  The reason that I have the "/.." is
because node was at the component-attribute level.  Every reference I made was
../ @attribute.  The trailing "/.." took me back to the component node level
and therefore was much easier to make the @status and @estimate references
without the "../" prefixes.

>As a side issue I note that you are combining  indent="yes" with explictly
addded indentation eg

          <xsl:value-of select="$indent"/>
          (<xsl:value-of select="@estimate"/>)

>which adds the value of $indent followed by 10 spaces and a ( before the
estimate.

Because the end result generates HTML.  In order to make a simple example to
illustration of the problem I am experiencing, I removed all HTML tags for
clarity.  I use the indent="yes" for nice HTML formatting, but not for display
formatting.  The above data would be in an HTML table.  I will continue to use
the indent, because I want a much smaller outline indent than the HTML LI tags
provide.  The (@estimate) is the time estimate to develop that particular
component.  My end goal of this project is to provide time estimates to build
each phase of a project.  I put it in Parenthesis, because I stripped out all
the HTML to simplify my problem.  This value will end up in it's own column
with a subtotal per phase of delivery.

In reference to your solution:

Thank you very much for taking the time to respond.  I like your idea.  I have
a concern that apply-templates will apply all templates in the XSL stylesheet,
when I only want this one to execute.  Can this same process be done with a
call-template?  This two pass concept is foreign to me, do you know a website
with good working examples?

<xsl:template match="/">
<xsl:variable name="x">
<xsl:apply-templates/>
</xsl:variable>
<xsl:apply-templates select="xalan:node-set($x)"/>
</xsl:template>

Thank you,

Pat
