Now, as far as importing xml files, I have never been successful at
importing mathml and must assume that this is accomplished through some
secret handshake as well ;-)
for example, an attempt to import test.xml which consisted of the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE math PUBLIC "-//W3C//DTD MathML 2.0//EN"
I had tested that very same example before I had answered. Besides the
fact, that the character ⁢ is rendered wrong, the import is
So there must be some difference between my and your way. So next try
with a step by step description:
Precondition: The MathML is saved as file on disk, for example "mymath.xml".
1. Open a Writer document or use a new one. Set the cursor where the
formula should be.
2. Insert > Object > Formula. Now the equation editor is open. The top
menu has changed, a part of the writer document is shown, with a
rectangle where the formula will be, and a command window with a
blinking cursor exists.
4. Tools > Import Formula. You get a file picker. Choose your
MathMl-file, here mymath.xml. Click on button 'Insert'.
5. Now you have the proper command in the command window. If something
is wrong (for example the character ⁢ mentioned above), you can
6. Klick outside the formula into your Writer document. Finished.
An attempt to export similar code as writer xml was similarly
ineffective on import.
If you only want to convert a single formula to MathML and your formula
is inside a Writer document, then right-click the formula. The context
menu opens and the last item is "Save as...". Use this and select
"MathML" from the list of available file formats. You will get a single
MathML file. It does not matter whether you use the file extension .mml
Reimporting this file as described above, gives the same formula as
exported, because the original LO formula is written to an annotation
element and read when imported.
You should use grouping brackets to generate a well structured formula
in LO, although LO does not need them to render the formula. It will
give better results in export.
If you want to export the whole Writer document with an easy access to
the MathML without unzipping, you can use File > Export > type XHTML, or
File > Save as > type "Flat XML".
Do you understand German? Than the German "Handbuch für Math" on
