Next, the in-object element position analysis unit 105 examines the relationship between the element and the object.
For this purpose, an object identifier is given from the in-object element analysis unit 105 to the object information storage unit 109, and the data of the constituent elements of the object is extracted. The data of the constituent elements also includes information on the head element, the end element, and the arrangement order. Then, the in-object element analysis unit 105 checks the relationship between the specified element and the object based on the identifier of the specified element and the data of the constituent element. Here, the relationship is considered in the following three ways.

Relation 1: specified element = head element = end point element That is, a case where the object is composed of one element.

Relation 2: head element ≠ end element and specified element = head element, or head element ≠ end element and
Specified element = end point element. That is, when the object is composed of a plurality of elements, and the specified element is located at the end of the object.

Relation 3: head element ≠ end element, where head element <designated element <end element. That is, the object is composed of a plurality of elements, and the specified element is not the end of the object.

In accordance with each of these relationships, the element information updating unit 107 and the object information updating unit 106 perform element erasure and object reconstruction in the following procedures. Note that specific examples of the processing are shown in FIGS.
