Determining a style class based on an xml attribute.

Hi Kannan,

This issue has been discussed quite often on this list. AFAIK there
is only one way to do what you want - to use XForms construct like
xforms:group or xforms:relevant as a wrapper for your HTML tags to
hide/reveal them. Something like this could work in your case:

<xforms:group ref="instance('output')/bids/bid[overdue = 'true']">
        <xhtml:span class="overdue">content</xhtml:span>
</xforms:group>
<xforms:group ref="instance('output')/bids/bid[overdue = 'false']">
        <xhtml:span class="regular">content</xhtml:span>
</xforms:group>

Erik also mentioned that future version of OF will support AVTs on
XHTML elements so there is (a glimmer of) light at the end of the
tunnel.

Thanks Alexandar,
I was trying to remove the "content" duplication between both spans(which in my case is 100 odd lines). Anyways, in the below solution, I have one more question though. I am trying this inside xf:repeat element, which means that the xhtml looks like,
<xf:repeat nodeset="instance('output')/bids/bid>
      <xf:group ref="[overdue='true']">
        <span and content>
      </xf:group>
      <xf:group ref="[overdue='false']">
        <span and content>
      </xf:group>
</xf:repeat>

Now it is cribbing that XPath syntax error at char 0 in {[partReturnRejected}: Unexpected token "[" in path expression.

Now In the repeat element I am on the Bid node, so i cant say /bid[partReturnRejected='true'], I also tried getting value part but not quite getting it. Can you help me in this?

Regards,
Kannan
