apply-string-subst-map — Apply a string-substitution map
This function applies a “string substitution” map. Use it when
you want to do multiple string substitutions on the same target
content. It reads in two things: content, the
content on which to perform the substitution, and
map.contents, a node set of
elements (the names of the elements don't matter), with each element
having the following attributes:
oldstring, a string to
be replacednewstring, a string with
which to replace oldstring
The function uses map.contents to
do substitution on content, and then
returns the modified contents.
This function is a very slightly modified version of Jeni
Tennison’s replace_strings function in the
multiple string replacements section of Dave Pawson’s
XSLT
FAQ.
The apply-string-subst-map function is
essentially the same function as the
apply-character-map function; the only
difference is that in the map that
apply-string-subst-map expects, oldstring and newstring attributes are used instead of
character and string attributes.
