Hello,
I am wondering whether it would be possible to have a callback semantic
action in liblouisutdml where the callback function will provide
alternative XML for the element for liblouisutdml to use.
Such a use would be in processing word document files when an OLE
object, I have MathType objects particularly in mind, are encountered.
On encountering the element, liblouisutdml would call the specified
callback (ideally a C callback function, but if that's too hard may be a
shell execution of a command), passing it the element and sub-element
XML, and the callback would return the substitution XML for
liblouisutdml to use.
Would such a feature be difficult to implement? I know for myself using
python or Java this would not be too complicated to add to a library
written in those languages but C is not one of my strong points.
Yes I know that may be pre-translation conversion could achieve the same
result, but say in the MathType case, substituting the MathML in to the
OpenXML would probably break the file so that it would not work in word
and also for OpenXML may not be legally permitted by the license
Microsoft impose on the format.
