<P>PROBLEM TO BE SOLVED: To efficiently convert a data structure between a structured document and a table on an RDB, and to flexibly link them. <P>SOLUTION: As for a node in the lower order of a node to be processed in a structured document 1a, data update definition 3a to define the correspondence to a table in an RDB 2 being the target of operation is used to set a route node in the structured document 1a as an object to be processed (a step S2-1), and iteration elements are extracted from a node instructed from the data update definition 3a, with the node set as the object to be processed as a start point (step S2-2), and element contents or attribute values made to correspond to the table are extracted from the structured document for every node extracted as the iteration elements, and processing to request the update of the table is executed (steps S2-3 to S2-6), and when the extraction of the repeated elements from the low order node is designated, the extracted node is newly set as an object to be processed, and the steps S2-2 to S2-6 are executed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
