Hi,
I am trying to fill the HTML <link rel="next"> and <link rel="prev"> with
content through XSLT.
I have a xml document that contains the sorted sequence of the pages. It
looks like this;
...
<li id="tinnsoldaten" href="tinnsoldaten.html">The Steadfast Tin
Soldier</li>
<li id="klatremusiknipe" href="klatremusiknipe.html">Vole in Trouble</li>
<li id="kariusogbaktus" href="kariusogbaktus.html">Karius and Baktus</li>
<li id="veslefrikk" href="veslefrikk.html">Little Freddy and his Fiddle</li>
...
When processing the the page with the id="klatremusiknipe" I want to fill
the link elements like follows;
<link href="tinnsoldaten.html" rel="prev" />
<link href="kariusogbaktus" rel="next" />
... as "tinnsoldaten" is the page listed before the current and
"kariusogbaktus" is the one listed just after.
The way I believe I need to go about this is first find the <li> element
that has the same id as the page I am processing. Then print out the href
attribute of the preceding and following sibling. Sadly my understanding of
writing xpath expressions using these axis are weak.
I currently have the following none working solution;
$html-head-link-id= id of the current page being processed
$id-submenu-list= the sorted list of pages described above
These are the expressions that against my will validate to nothing when
run...
<xsl:variable name="html-head-link-next"
select="$id-submenu-list/following-sibling::li[(_at_)id=$html-head-link-id][1]"
/>
<xsl:variable name="html-head-link-prev"
select="$id-submenu-list/preceding-sibling::li[(_at_)id=$html-head-link-id][1]"
/>
Any suggestions to what the correct xpath syntax would be for this case is
highly appreciated.
Thank you.
Best regards,
Mario Caprino
