<p>PROBLEM TO BE SOLVED: To provide an encoder capable of increasing encoding ratio of an XML document including an extension element defined with a wild card by creating an EXI grammar reflecting an extension schema corresponding to the extension element defined by the wild card.SOLUTION: The encoder includes: an encoding section that encodes an XML document from a start point toward an end point of the XML document and detects the extension element between the start point and the end point of the XML document; and a combining section that generates a third EXI grammar in which a first EXI (Efficient XML Interchange) grammar which is generated based on a basic schema and a second EXI grammar which is generated based on an extension schema prescribing structure of the extension element are combined. The encoding section performs encoding on the basis of the first EXI grammar until detecting the extension element from the start point of the XML document, and after detecting the extension element in the XML document, performs encoding on the basis of the third EXI grammar.</p> |
