I am converting a large body of legacy XML documents to a DITA-based format using
Oxygen 12. One of the problems with the document I'm currently working on is that
about 15 different element names in the source will be turned into<topic>
elements. I'm finding that I'm having to repeat those 15 elements in various
templates in order to create the document maps, normalise cross references, etc. This
makes the code difficult to read and is also prone to error if I accidentally miss
off one of the elements in a given location.
Is there any way in XSLT 2.0 that I can define the source elements as a group
and then refer to that in templates, for-each loops and so on? Or are there any
extension functions out there that might help?
Thanks!
If there's a schema, and if you're lucky, the elements will be defined
as members of a substitution group, so you can refer to them
collectively as schema-element(G) where G is the name of the
substitution group head. Alternatively, you might find they are all
defined with type T, so you can refer to them as element(*, T).
Without schema support, the only thing that comes to mind is to write a
function
<xsl:function name="f:is-topic" as="xs:boolean">
<xsl:param name="e" as="element()"/>
<xsl:sequence select="exists($e[self::A or self::B or self::C....])"/>
</xsl:function>
and use this for example as match="*[f:is-topic(.)]"
