Hello there, apologies in advance if this question has an obvious answer! I
don't usually rush to use this list.
I am working on a simple FAQ programme that uses xsl and xml to allow a user
to add (and edit) questions to the list (by updating the original source xml
file).
I want to differentiate between the first five <faq>s and the rest so I can
add appropriate formatting to distinguish between two groups of questions on
a web page (recent and previous).
The xsl below only selects the *most* recent question - which is equivalent
to <lastid>.
I'm looking for a way to express: $lastid = a range of id values [the higest
five values of this element.
Each time a user submits a question - it is given a 'new' id (previous
lastid+1) and the <lastid> element is updated correspondingly.
I've been trying to use the position() command to achieve this - but to no
effect.
The code is:
*XML*
<faqs>
<lastid>2</lastid>
<faq>
<id>1</id>
<question>this is a question</question>
<answer>this is an answer</answer>
</faq>
<faq>
<id>2</id>
<question>another question</question>
<answer>another answer</answer>
</faq>
...
</faqs>
*XSL*
<xsl:param name="lastid" select="/faqs/lastid"/>
<xsl:param name="id"/>
....
<xsl:for-each select="/faqs/faq">
<xsl:sort select="id" order="descending"/>
<xsl:choose>
<xsl:when test="id=$lastid">
<xsl:element name="A">
<xsl:attribute name="href">#q<xsl:value-of
select="id"/></xsl:attribute>
<font color="red"><xsl:value-of select="question"/></font>
</xsl:element><br/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
....
Any help would be much appreciated.
Thanks
