RE: Doublet

Hi Sven,

You're dealing with a typical grouping problem, in XSLT this is done using
xsl:key, generate-id(), and key(); try this stylesheet on your XML (I've
used HTML as the output):

<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:key name="ids" match="*[(_at_)id]" use="@id" />

<xsl:template match="/tc">
  <table>
    <tr><th>Id</th><th>Name</th></tr>
        <xsl:apply-templates select="pc" />     
  </table>
</xsl:template>

<xsl:template match="pc">
    <xsl:apply-templates
      select="*[(_at_)id and generate-id(.)=generate-id(key('ids', @id))]" />
</xsl:template>

<xsl:template match="*[(_at_)id]">
  <tr>
    <!-- first column is the value of the id attribute -->
    <td><xsl:value-of select="@id" /></td>
    <!-- second column is the name -->
    <td><xsl:value-of select="@name" /></td>
  </tr>
</xsl:template>

</xsl:stylesheet>

It outputs:

<?xml version='1.0' ?>
<table>
<tr><th>Id</th><th>Name</th></tr>
<tr><td>1</td><td>10000</td></tr>
<tr><td>2</td><td>10001</td></tr>
<tr><td>3</td><td>1</td></tr>
</table>

I've tested it with StylusStudio 6 Release 2.

Cheers,
<prs/>

Hi everybody,

i got following result:

10000
10001
1
10000

I want to have:

10000
10001
1

I don't want to get doublets.

Does anybody know something about it?

Thanks in advance and best regards
Sven
