Subject: Re: [xsl] Grouping by letters but keep symbols together From: "Christophe Marchand cmarchand@xxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Fri, 25 Jan 2019 17:41:06 -0000 |
In addition, the DITA Community i18n project on GitHub (https://github.com/dita-community/org.dita-community.i18n) provides general-purpose Saxon extensions and XSLT 2+ support for locale-aware grouping, sorting, word and line breaking, and text size approximation. (The code was originally developed to do generation of paginated EPUBs in a number of languages, thus the need for locale-aware word and line breaking as well as text size approximation in addition to sorting and grouping.)
While the code was developed for use with DITA docs it's not DITA-specific. The current Java extensions are only bound to Saxon 9.1 because I didn't have client funding to also do the Saxon 9.6+ integration. It shouldn't be that hard but it's not something I've been able to pursue.
This project includes dictionary-based Simplified Chinese features by integrating an open-source Simplified Chinese dictionary.
Cheers,

Beyond all these suggestions, I always create functions that return grouping and sort keys as the logic could be much more sophisticated, especially if you bring in locale-aware processing.

I'd use a Unicode character category match for this:
<xsl:for-each-group select="glossentry"
group-by="(substring(upper-case(glossterm),1,1)[matches(.,'\p{Lu}')],'NON-LETTER-GROUP')[1]">
<topicref navtitle="{current-grouping-key()}" toc="no">
...
</topicref>
</xsl:for-each-group>
What you put in for "NON-LETTER-GROUP" might depend on where or how
you're sorting the glossary entries.
