Mallard Glossaries
Common templates for the Mallard Glossary extension.

This stylesheet contains utility templates for locating and linking to terms
with the Mallard Glossary extension.
-->

<!--++==========================================================================
mal.gloss.key
Get a #{gloss:term} element from its #{id} attribute.

This key returns #{gloss:term} elements based on their #{id} attribute. This
key only applies to elements inside a cache file. Make sure to make the cache
file the context document before calling this key.
-->
<xsl:key name="mal.gloss.key"
         match="/cache:cache//mal:info/gloss:term[@id]"
         use="@id"/>

<!--**==========================================================================
mal.gloss.match
Determine whether a glossary term matches a criterion.
$match: A #{gloss:match} element containing criteria.
$term: A #{gloss:term} element to attempt to match.

This template determines whether a glossary term matches a condition, as given
by a #{gloss:match} element. If the term matches, an empty string is output.
Otherwise, a non-empty string is output.

To determine if a term matches a set of matches, call this template for each
#{gloss:match} element, then check if the concatenated result is empty.
-->
<xsl:template name="mal.gloss.match">
  <xsl:param name="match"/>
  <xsl:param name="term"/>
  <xsl:if test="$match/@tags and not(str:split($match/@tags) = str:split($term/@tags))">
    <xsl:text>x</xsl:text>
  </xsl:if>
</xsl:template>

<!--**==========================================================================
mal.gloss.terms
Output the glossary terms for a page or section.
$node: The glossary #{page} or #{section} to output terms for.

This template outputs the terms that should be displayed for ${node}.This output
is a result tree fragment. To use these results, call #{exsl:node-set} on them.
This template locates all terms throughout all pages and filters them based on
any #{gloss:match} elements in the #{info} child of ${node}, and also excludes
terms that are matched by child sections of ${node}.

The filtered terms are then grouped by matching ID. For each unique ID, this
template outputs a #{gloss:term} element with the corresponding #{id} attribute.
Each of these elements contains #{title} elements reflecting the titles in the
actual term definitions. These titles have duplicates removed, compared by the
space-normalized string value, and are sorted.

These #{gloss:term} elements then contain further #{gloss:term} elements, which
are copies of the actual terms with the same ID. These elements have an #{xref}
attribute added containing the ID of the containing page.

The top-level #{gloss:term} elements and the #{gloss:term} elements they contain
are not sorted. Only the #{title} elements in the top-level #{gloss:term}
elements are sorted.
