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_end_namespace_decl_handler - Set up end namespace declaration handler

SYNOPSIS
bool xml_set_end_namespace_decl_handler (resource $parser, callable $handler) DESCRIPTION
Set a handler to be called when leaving the scope of a namespace declaration. This will be called, for each namespace declaration, after the handler for the end tag of the element in which the namespace was declared. PARAMETERS
o $parser - A reference to the XML parser. 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, and should return an integer value. If the value returned from the handler is FALSE (which it will be if no value is returned), the XML parser will stop parsing and xml_get_error_code(3) will return XML_ERROR_EXTERNAL_ENTITY_HANDLING. handler (resource $parser, string $prefix) o $parser - The first parameter, parser, is a reference to the XML parser calling the handler. o $prefix - The prefix is a string used to reference the namespace within an XML object. 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. NOTES
Note This event is not supported under LibXML. SEE ALSO
