Hi all, I want to write a preprocessor in Ruby to hande input of the form:
<math xmlns="http://www.w3.org/1998/Math/MathML"; id="1.1.5.1.1.3"> <mtext id="1.1.5.1.1.3"> <neg id="1.1.5.1.1.3#0"/> <exists id="1.1.5.1.1.3#1"/>x x<in id="1.1.5.1.1.3#4"/> <emptyset id="1.1.5.1.1.3#5"/> </mtext> </math> I would like to remove the namespace declaration and convert the elements within mtext to the corresponding Unicode characters. As the elements are *not* actually MathML, will probably need to construct the translation table myself, like so: tr = { "exists" => "2203", "in" => "2208", ... } I think I can use the definitions given here (and change the names where necessary): http://www.w3.org/TR/REC-html40/sgml/ entities.html#h-24.3.1 Is there a way to read the input file into a DOM tree and modify it in place, or do I have to traverse it an build a new tree along the way? Many thanks in advance for any pointers!
