nested xsl:for-each

XSLT
i am trying, unsuccssefully , to code some xslt to outpout html,

ihave a node(publications), publication node has 3

Publication Node
- pub1
pub1 offer 1

pub1 offer2

pub1 offer3
- pub2
pub2 offer1

pub2 offer2
- pub3
pub3 offer1

what im trying to do is have the properties of each publication node show in the publication page like so

pub1 pub2 pub3

pub1 offer1 pub2 offer1 pub3 offer1

pub1 offer2 pub2 offer2

pub1 offer3

here's my effort which, is fine apart from repeating all the offers below each publication

<xsl:param name="currentPage"/>

  <xsl:variable name="subPubs" select="$currentPage/Publication"/>

<xsl:template match="/">
  <xsl:for-each select="$subPubs"> 

  <xsl:variable name="ID">
  <xsl:choose>
  <xsl:when test="position() = 1">sub-left</xsl:when>
  <xsl:when test="position() = 2">sub-right</xsl:when>
  <xsl:when test="position() = 3">sub-far-right</xsl:when>
  </xsl:choose>
  </xsl:variable>
  
  <div id="{$ID}" class="subs-offer-details">
  <h2><xsl:value-of select="./title" />
  </h2>
  <img src="images/blank.png" width="300" height="200" />
  <xsl:value-of select="./description" disable-output-escaping="yes"/>
  </div>

  <xsl:for-each select="$subPubs/offer">
<p> <xsl:value-of select="./title" /></p>
  </xsl:for-each>
  </xsl:for-each>



</xsl:template>

just starting out in xslt, any help would be appreciated,

I am just doing almost the same thing. At the moment it outputs

<dl>
<dt>Pub 1</dt>
<dd>Image cropper</dd>
<dd>Downhill Chile Mountain Bike</dd>

<dt>Pub 2</dt>
<dd>pub 2offer 1</dd>
</dl>

I have done this with, translated into new schema:

  <xsl:variable name="selectedNodes" select="$currentPage/Publication"/>

  <xsl:if test="count($selectedNodes) &gt; 0">
        
    <dl>
      <xsl:apply-templates select="$selectedNodes">    
        <xsl:sort select="@sortOrder" order="ascending"/>        
      </xsl:apply-templates>
    </dl><!-- end #children -->
    
  </xsl:if>

</xsl:template>

<xsl:template match="Publication">
  
  <dt><xsl:value-of select="@nodeName"/></dt>
    
   <!-- Now select the child nodes, change offer to NodeTypeAlias of child node -->
    <xsl:apply-templates select="./offer">    
        <xsl:sort select="@sortOrder" order="ascending"/>        
    </xsl:apply-templates>
   
</xsl:template>

<xsl:template match="offer">
  <dd><xsl:value-of select="@nodeName"/></dd>
</xsl:template>

If you are not getting quite what you expect, insert <xsl:copy-of select="."/> and it will out the XML that is being processed, view in page source.

Thanks Richard,

I now have it working to a fashion, however the output is still not quite right (below)

what im trying to achieve is

imty most recent script :

<xsl:param name="currentPage"/>

<xsl:template match="/">

<xsl:variable name="selectedNodes" select="$currentPage/Subscriptions"/>

  <xsl:if test="count($selectedNodes) > 0">

  <p>
  <xsl:apply-templates select="$selectedNodes">
  <xsl:sort select="@sortOrder" order="ascending"/>
  </xsl:apply-templates>
  </p>

  </xsl:if>

</xsl:template>

<xsl:template match="Subscriptions">
  <xsl:variable name="ID">
  <xsl:choose>
  <xsl:when test="position() = 1">sub-left</xsl:when>
  <xsl:when test="position() = 2">sub-right</xsl:when>
  <xsl:when test="position() = 3">sub-far-right</xsl:when>
  </xsl:choose>
  </xsl:variable>

  <div id="{$ID}" class="subs-offer-details">
  <h2><xsl:value-of select="./subtitle" />
  </h2>
  <img src="images/blank.png" width="300" height="200" />
  <xsl:value-of select="./description" disable-output-escaping="yes"/>
  </div>

  
  <xsl:apply-templates select="./SubscriptionOption">
  <xsl:sort select="@sortOrder" order="ascending"/>
  </xsl:apply-templates>

</xsl:template>

<xsl:template match="SubscriptionOption">


  <ul>
  <li><xsl:value-of select="@nodeName"/>From  £<xsl:value-of select="./price" /></li>
  </ul>

</xsl:template>

have tried everything i could think of...........

Grant,

I expect that the SubscriptionOptions call should be inside the DIV with class subs-offer-details, like:

           <div id="{$ID}" class="subs-offer-details">
              <h2><xsl:value-of select="./subtitle" /></h2>

              <!-- Now select the child nodes, change offer to NodeTypeAlias of child node -->
               <xsl:apply-templates select="./SubscriptionOption">    
                 <xsl:sort select="@sortOrder" order="ascending"/>        
              </xsl:apply-templates>
              <img src="images/blank.png" width="300" height="200" />
              <xsl:value-of select="./description" disable-output-escaping="yes"/>
            </div>
