摘要

PROBLEM TO BE SOLVED: To enhance the efficiency of encoding (compression) of XML data. SOLUTION: A syntax (type) generator 2-1 is used to convert a DTD into ASN. 1 abstract syntax (type), and a separator 2-2 is used to separate text from XML data according to the DTD. A syntax (value) generator 2-3 is next used to convert the XML data (syntax of elements) from which the text is separated into ASN.1 abstract syntax (value) according to the ASN.1 abstract syntax (type). A transfer syntax generator 2-4 is then used to convert the ASN.1 abstract syntax (value) into ASN.1 transfer syntax. A compressor 2-5 is used to compress the separated text. A merger 2-6 is further used to merge the ASN.1 transfer syntax and the compressed text to generate encoded XML data.
