Generate linked alphabet for index

[ann.jensen]

Hi,
I have had a client request to generate an alphabet with linked letters at the top of indexTerms.html to provide quick access to the index contents for a given letter e.g. T.
Can anyone advise on where such a customisation would be implemented?
Thanks in advance,
Ann

Hi Ann,

Interesting idea, I will also add an improvement request for this to our internal issues list.
I assume you want this for WebHelp Responsive.
In the XSLT stylesheet:

OXYGEN_INSTALL_DIR\frameworks\dita\DITA-OT2.x\plugins\com.oxygenxml.webhelp\xsl\dita\responsive\createMainFilesImpl.xsl

there is an XSLT template which generates the entire index list grouping index terms in categories:

Code: Select all

 <xsl:template match="index:index" mode="create-index">



 ......................
 

in that XSLT template, after the variable named "collation" is defined you can iterate all existing letter categories and create a list of links:

Code: Select all

    <xsl:for-each-group select="index:term" group-by="

      upper-case(

      translate(

      substring(

      normalize-unicode(@sort-as, 'NFD'), 1, 1), $katakana_chars, $hiragana_chars))" 

      collation="{$collation}">

      <a href="#index_category_{current-grouping-key()}"><xsl:value-of select="current-grouping-key()"/></a>

      <xsl:text> </xsl:text>

    </xsl:for-each-group>

Further down, for each letter a list item is created:

Code: Select all

<li class="wh_term_group">

........

and you need to set an @id attribute on it so that the links to it start working:

Code: Select all

<li class="wh_term_group" id="index_category_{current-grouping-key()}">

..............

Radu

Thank you so much for that.
It works a treat
