I've been stumped on the for ages, please help.

I seem to have a problem with my XPath - the first element is not being picked up in the for-each loop when $grid_width = 3. Can anyone see why this is happening. The expression (../@xads_user_profile_id=exclusive/@xads_user_profile_id) in the for-each seems to be doing the damage.

Thanks in advance,

Darren Clump

XSLT - snip
-----------
The below is to create a table. When $grid_width = 5 there is no problem all the assets are picked up! However when the $grid_width = 3 the first asset is passed over!!

<xsl:for-each select="asset[(position() mod $grid_width = 1) and (@is_exclusive='true') and (../@xads_user_profile_id=exclusive/@xads_user_profile_id)]">
    <tr>
        <xsl:apply-templates select="(following-sibling::asset[(position() &lt; $grid_width)]) | ."/>
    </tr>
</xsl:for-each>

XML - snip
----------
<content xads_user_profile_id="1240871">
    <asset is_exclusive="true" content_type="image" label="KJFX007_NB" id="50190114" expired="false"/>
    <asset is_exclusive="true" content_type="image" label="KJ-FX-005CR" id="50190117" expired="false"/>
    <asset is_exclusive="true" content_type="image" label="KJ-FX-12" id="50666231" expired="false">
        <exclusive xads_user_profile_id="1240871" perm_level="50"/>
    </asset>
    <asset is_exclusive="true" content_type="image" label="KJ-FX-10" id="50666234" expired="false">
        <exclusive xads_user_profile_id="1240871" perm_level="50"/>
    </asset>
    <asset is_exclusive="true" content_type="image" label="KJ-1967" id="50666448" expired="false">

    </asset>
    <asset is_exclusive="true" content_type="image" label="KJ-1899" id="50666451" expired="false">
        <exclusive xads_user_profile_id="1240840" perm_level="10"/>
    </asset>
    <asset is_exclusive="true" content_type="image" label="KJ-3777" id="50670463" expired="false">
        <exclusive xads_user_profile_id="1240871" perm_level="50"/>
    </asset>
</content>

Could you state what is needed. "position() mod 5" only equals 1 when the position equals 6, 11, 16 etc.

position()mod 5 (6,11,16..) - this is what the desired result is!! Hence if there are a certain number of assets a new row is made for the table.
The desired result for grid width = 3 if there are 5 and 8 desired assets is
<tr>
  <td>asset</td><td>asset</td><td>asset</td>
  <td>asset</td><td>asset</td><td><td>
</tr>
<tr>
  <td>asset</td><td>asset</td><td>asset</td>
  <td>asset</td><td>asset</td><td>asset</td>
  <td>asset</td><td>asset</td><td></td>
</tr>

the same priciple applies for grid_width=5

<asset is_exclusive="true" content_type="image" label="KJ-FX-12" id="50666231" expired="false">
    <exclusive xads_user_profile_id="1240871" perm_level="50"/>
</asset>

is not getting picked up - but I want to display it!!

Thanks Darren

Hi,

First of all, the XPath expression
will give the nodes at positions 1, N + 1, 2*N + 1, 3*N + 1, etc.
So, in your example, when grid_width=3, according to your XSLT, you'll get the nodes from 4-th to 6-th as the result of one pass of the xsl:for-each (the first node is passed over, since the condition is not met) and the 7-th node as the result of the second pass of the xsl:for-each. If you'll drop the condition I mentioned just above, you'll get all assets, since the first asset also will be included which in turn will "bring" assets standing at positions 2 and 3. So, if you want to see also the asset
you can drop that condition, for example.
But one point was strange for me: how can you get the first asset(by the same XSLT code you presented) when the grid_width=5?

Sorry I think I've caused some confusion about which asset's I want to select.

With regards to the XML in the inital post, I want to match "assets" with @label (attribute) = KJ-FX-12, KJ-FX-10 and KJ-3777 (the assets that match the condition parent::content/@xads_user_profile_id=exclusive/@xads_user_profile_id).

When refering to the first asset - I ment the first desired asset (@label="KJ-FX-12").

if you wrap the below around the inital XSLT snip and run it against the initial XML snip (provided above) the problem will be apparent.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="content">
    <xsl:variable name="grid_width" select="3"/>
:
XSLT snip
:
</xsl:template>
<xsl:template match="asset">
    <td> asset name <xsl:value-of select="@label"/></td>
</xsl:template>
</xsl:stylesheet>

Thanks in advance,
Darren

Ok, I hope I've understood what you want to do ;)

Here is the XSLT code:

I think the "following-sibling" axis confused you: it's applied on the original document order.

If this still isn't the result you meant, let me know.

I forgot to remove the line

:D

It was there to show the current value...
