Abstract

A method, system, and computer-readable code for reducing Extensible Markup Language (XML) and Document Type Definition (DTD) document file size through one or more novel compression techniques. In one aspect, a compression technique for tags is defined that reduces the size of tags within either or both of XML and DTD files. In another aspect, a compression technique for attributes within tags may be used to further reduce file size (again, in either XML or DTD files). In a further aspect, a compression technique for strings within an XML file is defined, whereby the decompression will be performed automatically by an XML parser. While these compression techniques are described with reference to XML, they may also be used advantageously with other notations derived from SGML (Standard Generalized Markup Language).
