Waw, I wish I could be so optimistic...

As others state the "conversion", does, I believe need some intelligence 
and, not the least, some "contextualization".

Aside of the computer-algebra systems (Maple, Mathematica, soon MuPad, 
GAP, Yacas) which generate MathML-content at least from within their 
human-readable syntax, I would note two more things (not really 
inputting MathML-presentation):
-> the QMath processor (start at http://www.matracas.org/) is a tool 
which accepts a textual syntax closer to that of these 
computer-algebra-systems and creates OpenMath out of it (which then not 
too hard to convert into MathML-content). QMath is extensible and can, 
with some work (the contextualization), be used to convert formulae in a 
TeX source into formulae in OpenMath
-> the efforts of the team of Stephen Watt at ORCCA (Londong, Ontario) 
which have a LaTeX to MathML trying to convert most possible LaTeX into 
some semantic encoding (which gets enriched as it goes), producing the 
conversion-stylesheets to MathML-presentation as well

And I think and wish I had forgotten others.
