i'll build it for a fee. :-)
I don't think its "required" if the input can be limited to something reasonable. Not that I would want to try and code such a parser myself even for a limited set of equations.

Of course a lexicographical parser would be a great solution if money and time were no problem. Smilie

xml_set_character_data_handler - Set up character data handler

SYNOPSIS
bool xml_set_character_data_handler (resource $parser, callable $handler) DESCRIPTION
Sets the character data handler function for the XML parser $parser. PARAMETERS
o $parser - A reference to the XML parser to set up character data handler function. o $handler -$handler is a string containing the name of a function that must exist when xml_parse(3) is called for $parser. The function named by $handler must accept two parameters: handler (resource $parser, string $data) o $parser - The first parameter, parser, is a reference to the XML parser calling the handler. o $data - The second parameter, $data, contains the character data as a string. Character data handler is called for every piece of a text in the XML document. It can be called multiple times inside each frag- ment (e.g. for non-ASCII strings). If a handler function is set to an empty string, or FALSE, the handler in question is disabled. Note Instead of a function name, an array containing an object reference and a method name can also be supplied. RETURN VALUES
Returns TRUE on success or FALSE on failure. PHP Documentation Group XML_SET_CHARACTER_DATA_HANDLER(3)
