Document processing apparatus and method

A document processing method of processing original data having a print format as an attribute, comprising steps of:

• holding original data in a tree structure by giving an attribute to each node;
• and
• when separating arbitrary partial tree data in the tree structure into a plurality of partial tree data, replacing an attribute of each separated partial tree with an attribute of a node of the partial tree data in accordance with an attribute before separation.

A document processing apparatus which processes original data having a print format as an attribute, comprising:

• a holding unit which holds original data in a tree structure by giving an attribute to each node;
• and
• a replacement unit which, when arbitrary partial tree data in the tree structure held by said holding unit is separated into a plurality of partial tree data, replaces an attribute of each separated partial tree with an attribute of a node of the partial tree data in accordance with an-attribute before separation.

A computer program product which records a program for causing a computer to process a structured document formed by grouping original pages, wherein the program comprises

• a code for a display control step of controlling display of image objects of either or both of a document structure and an original page contained in the document, and
• a code for an editing step of editing the document so as to insert a new group containing a designated original page to a designated position in accordance with designation of the original page and the position on the image objects displayed in the display control step,
• wherein in the display control step, display of the image objects is controlled for the document edited in the editing step.
