Parsing MathML

MathML documents should be validated using the XML DTD below. Note in particular that the xml attribute xml:space is not used, so whitespace characters in element content (ie. outside the presentation token elements mi, mo, mn, mtext, mspace, mtext, ms , the content token elements ci, cn and annotation) are not significant.

If the MathML is parsed without a DTD (ie. as a well-formed XML fragment), it is the responsibility of the processing application to treat these whitespace characters as not significant.

An SGML parser (such as nsgmls) can be used to validate MathML. In this case an SGML declaration defining the constraints of XML applicable to an SGML parser must be used. See http://www.w3.org/TR/NOTE-sgml-xml .


The MathML DTD

A zip file of the full DTD including entity declarations is provided for reference. Here we give the main body of the DTD, without including the entity declarations. See Chapter 6 for a list of entity names ordered by name or by unicode value.
