SGMLS.pm is an extensible perl5 class library for parsing the output from James Clark's popular sgmls and nsgmls parsers, available on the Internet at ftp://jclark.com. This is not a complete system for translating documents written the the Standard Generalised Markup Language (SGML) into other formats, but it can easily form the basis of such a system (for a simple example, see the sgmlspl program included in this package).
The library recognises four basic types of SGML objects: the element, the attribute, the notation, and the entity; each of these is a fully-developed class with methods for accessing important information.
