Document structure-editing program, document structure-editing method, document structure-editing apparatus, and computer-readable recording medium having document structure-editing program recorded thereon

摘要

A document structure-editing program which is capable of automatically generating difference information indicative of the differences between an old schema and a new schema. Document structure-defining information is edited by a document structure-editing device in response to an operating input. At this time, a record of an edit history indicating details of editing of the document structure-defining information is recorded on a storage device by an edit history-recording device, whenever the operating input is performed. Difference information indicative of the differences between the document structure-defining information before an edit and the same after the edit is generated by a difference information-generating device, based on the edit history recorded by the edit history-recording device.
