Hi

You'll have to excuse what I imagine is pretty bad xslt but I'm pretty new to this.

I've created an A to Z index for a site and display that data in a different page for each letter. The xslt searches the field "sitemapMetadata", that each page contains, and if that value starts with the letter that is defined in the A-Z index page then it pulls back a link to that page.

This all works fine(although I'm sure people could improve it) but what I'd like to do is be able to have more than one keyword in the "sitemapMetadata" field (perhaps seperated with e.g. a semicolon). So a page could appear more than once in the index e.g. a welcome page could appear under 'W' for Welcome but also 'H' for hello by putting in 'Hello;Welcome' in the sitemapMetadata field.

If someone could point me in the right direction of what I would need to do to do this, that would be great.

Thanks

Gavin

Code:

...will work but does not solve the sorting.

thanks for the help. It certainly does solve the issue of putting the link in the two pages that are defined in the sitemapMetadata but I use
Code:
<xsl:value-of select="current()/data[@alias='sitemapMetadata']/text()" />
to display the link which unfortunately shows the sitemapMetadata field as 'Hello;Welcome' on both 'H' and 'W' pages rather than Hello on the 'H' page and Welcome on the 'W' page.

So I thought that maybe it was possible to do something similar to that line, but being a bit new to this I haven't managed to get it right.

Any ideas/pointers?

Thanks

Gavin

that would be

Code:
<xsl:value-of select="current()/data[@alias='sitemapMetadata']/text()" />

erm, sorry I seem to be incapable of showing that line of code...

Code:
<xsl:value-of select="current()/data[@alias='sitemapMetadata']/text()" />

or <xsl:value-of select="current()/data[@alias='sitemapMetadata']/text()" />
or &lt;xsl:value-of select=&quot;current()/data[@alias='sitemapMetadata']/text()&quot; /&gt;

sorry I don't know which way will work to display that line so might have some gobbledegook as well :blush:
