Getting MathML in XML to display in Internet Explorer
================================================================================
The problem:
IE doesn't support XHTML, nor the combination of MathML namespaces
and XHTML namespaces to combine MathML in HTML. It _does_ "support"
what Microsoft calls "XML Islands", that is, XML fragments inside
text/html. That's just Wrong, but there you go.
Other browsers (like Mozilla) do the correct thing, and handle
MathML in XML using namespaces.
The solution:
Give everyone except IE files with the application/xhtml+xml MIME
type, and give IE the text/html MIME type, and in all other
respects give them the same file.
To do this, I have written a small CGI script. To use it, add the
following to the .htaccess file in the directory containing your
XHTML+MathML files:
# Convert XML files to HTML files if accessed by IE
Action xhtml /virtual/path/to/this/directory/xhtml-for-ie
AddHandler xhtml .xhtml
IndexIgnore xhtml-for-ie
<files xhtml-for-ie>
SetHandler cgi-script
</files>
You could of course put the CGI script anywhere, like a /cgi-bin/
directory, and you could give it a .cgi extension or whatever you
want. You could also call your files anything, here I have assumed
they have a .xhtml extension but it could be anything. Here is an
example of another possible fragment you could add to .htaccess to
get the same end result:
# Convert XML files to HTML files if accessed by IE
Action application/xhtml+xml /cgi-bin/xhtml-for-ie.cgi
This assumes that the script is in /cgi-bin/, that your files have
been set up to return with application/xhtml+xml (typically this
means having the .xhtml extension) and that files ending with .cgi
are automatically assumed to be CGI scripts.
Now install the CGI script, which you will find at
http://software.hixie.ch/utilities/cgi/xhtml-for-ie/xhtml-for-ie.pl
To 'install' it you need to put it in the directory you selected
when editing the .htaccess file. Don't forget to rename it as
appropriate (e.g., removing the .pl extension).
Now you are ready to start creating MathML files. To check it is
working, try copying
http://software.hixie.ch/utilities/cgi/xhtml-for-ie/example.xhtml
...to your directory. Assuming you used the first suggested change
above (i.e., the .xhtml extension for MathML-in-HTML files) this
should work in both Mozilla and IE.
