PROBLEM TO BE SOLVED: To realize a cooperative writing smoothly by enabling the restoration of a past document and the preparation of the document which does not exist in the past even if the document is freely edited by a writer without restricting the writer by editing. SOLUTION: In a word processor for which a structured data processing is applied to structured document data, the logical unit including at least either one of the contents part being a part of the contents of the structure document consisting of a tree structure or the anchor showing the related position with the structure of a subordinate hierarchy is held by a logical unit holding means 2, and the stream consisting of the logical unit located at the same hierarchy of the tree structure constituting the structure document is held by a logical unit group holding means 3. When the document structure is edited by a document editing means 5, a logical unit group generation means 6 newly generates the stream corresponding to the editing of the document and a reference relating means 7 relates the newly generated stream and a prescribed anchor. As a result, the newly generated stream is incorporated into an existing structured document and the structured document according to the edition of the document is prepared. |
