Hi all,

I was playing with convert Markdown + LaTeX to HTML + MathML with Pandoc.
I notice that the standalone HTML template used by Pandoc has a Javascript
function to convert MathML elements.

I ask at Pandoc list and John said that the Javascript was there for years.=
 I
believe that we don't need it anymore but want to check with you.

Cheers,
Raniere

When I ran

    $ cat sample.tex=20
    foo $x$ bar
    $ pandoc -v | head -n 1
    pandoc 1.13.2
    $ pandoc -s -f latex -t html --mathml sample.tex | head -n 33

      function convertMath(node) {// for Gecko
        if (node.nodeType=3D=3D1) {
          var newnode =3D
            document.createElementNS("http://www.w3.org/1998/Math/MathML",
              node.nodeName.toLowerCase());
          for(var i=3D0; i < node.attributes.length; i++)
            newnode.setAttribute(node.attributes[i].nodeName,
              node.attributes[i].value);
          for (var i=3D0; i<node.childNodes.length; i++) {
            var st =3D node.childNodes[i].nodeValue;
            if (st=3D=3Dnull || st.slice(0,1)!=3D" " && st.slice(0,1)!=3D"\=
n")
              newnode.appendChild(convertMath(node.childNodes[i]));
          }
          return newnode;
        }
        else return node;
      }

I notice the Javascript function convertMath for Firefox/Gecko. Wasn't clea=
r to
me why we need this. Anyone can give me a explanation?

Thanks,
Raniere
