How to loop through a DITA map and build a two-column table?

antoterrence · Post by **antoterrence** » Wed Nov 20, 2019 2:35 pm

Hi,
I want to loop through a dita map using XSLT and build a two-column html table.
First cell will contain first or even title and the second cell will contain the odd title.
I tried creating the following XSLT script but it skips the odd title. And it also populates the second cell in a row with the even title.
The

Code: Select all

following-sibling::following-sibling::*[contains(@class, 'map/topicref')][1

] axis is not working. It always returns the current even topicref node.
What am I doing wrong in the script?

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>

Hi,

I do not quite understand everything but positions and arrays in XSLT are 1 indexed, so the first element in the array is [1] and the first position() value is 1.

Also when you pass a parameter to a template and you want it to be a node set you do it like this:

Code: Select all

<xsl:with-param name="node" select="(following-sibling::*)[1]"/>

and then in the "get-document" template when you want to access stuff from that node instead of stuff like:

Code: Select all

<xsl:value-of select="@copy-to"/>

or

Code: Select all

 <xsl:when test="contains(@href,'#')">

you do this:

Code: Select all

<xsl:value-of select="$node/@copy-to"/>

and:

Code: Select all

 <xsl:when test="contains($node/@href,'#')">

because all the relative xpaths need to be relative to the "node" parameter.

Radu
