Description
In DocBook, there are generally two ways to refer to other
elements in the current document by ID: using the linkend
(or linkends
) attribute or using the xlink:href
attribute.
The f:xpointer-idref()
function returns the
ID portion of an XPointer that is a reference to another ID in the
current document.
In other words:
f:xpointer-idref('#foo')
isfoo
,f:xpointer-idref('id(foo)')
isfoo
,- and
f:xpointer-idref('http://example.org/#foo')
is the empty sequence.
