Technique for contracting element marks in a structured document

Claim 2

In a document processing system including a central processing unit, a random access memory and a display device, a method for hierarchically contracting a stream mark to an element mark about a reference point in a structured document in said random access memory in a database form, comprising the steps of: determining whether said reference point is inside said stream mark, contracting said stream mark to a largest element completely contained in said stream mark which also contains said reference point to produce an element mark; and, displaying said structured document on said display device emphasizing said element mark.

Claim 3

The method as recited in claim 1, wherein said reference point is the current document position which is represented on said display device by a cursor.

Claim 4

The method as recited in claim 1, wherein said structured document is in SGML format.

Claim 5

The method as recited in claim 1, wherein said method is invoked by a single user action.

Claim 6

The method as recited in claim 1, which further comprises the step of an additional editing operation on the contents of said element mark.

Claim 7

The method as recited in claim 1, wherein said structured document is displayed to the user in a WYSIWYG representation.

Claim 8

The method as recited in claim 2, which further comprises the steps of: contracting said element mark to a second largest element completely contained in said element mark which also contains the current document position to produce a child mark; and, displaying said structured document on said display device emphasizing said child mark.

Claim 9

The method as recited in claim 2, which further comprises the steps of: moving the current document position within said structured document; determining whether the current document position is inside said element mark; contracting said element mark to a second largest element completely contained in said element mark which also contains the current document position to produce a child mark; and, displaying said structured document on said display device emphasizing said child mark.

Claim 10

The method as recited in claim 1, wherein said element mark is emphasized by highlighting the alphanumeric text contained within said element mark.

Claim 11

In a document processing system including a central processing unit, a random access memory and a display device, a method for hierarchically contracting an element mark about a reference point in a structured document in said random access memory in database form, comprising the steps of: determining whether said reference point is inside said element mark; determining whether said element mark contains a child element which obtains said reference point; contracting said element mark to said child element to produce a child element mark; and, displaying said structured document on said display device emphasizing said child mark.

Claim 12

In a document processing system including a central processing unit, a random access memory and a display device, a method for hierarchically contracting an element mark about a reference point in a structured document in said random access memory in database form, comprising the steps of: determining whether said reference point is inside said element mark; determining whether said element mark contains a child element which obtains said reference point; contracting said element mark to said child element to produce a child element mark; and, displaying said structured document on said display device emphasizing said child mark.

Claim 13

The method as recited in claim 10, wherein said reference point is a current document position which is represented on said display device by a cursor.

Claim 14

The method as recited in claim 10, wherein said structured document is in SGML format.

Claim 15

The method as recited in claim 10, wherein said method is invoked by a single user action.

Claim 16

The method as recited in claim 10, which further comprises the step of an additional editing operation on said child element.

Claim 17

The method as recited in claim 10, wherein said structured document is displayed to the user in a WYSIWYG representation.

Claim 18

The method as recited in claim 11, which further comprises the steps of: determining whether said child mark contains a grandchild element which contains the current document position; contacting said child mark to said grandchild element to produce a grandchild element mark; and, displaying said structured document on said display device emphasizing said grandchild element mark.

Claim 19

The method as recited in claim 11, which further comprises the steps of: moving current document position within said structured document; determining whether the current document position is inside said child mark; determining whether said child mark contains a grandchild element which contains the current document position; contracting said child mark to said grandchild element to produce a grandchild element mark; and, displaying said structured document on said display device emphasizing said grandchild element mark.

Claim 20

A document processing system capable of hierarchically contracting a stream mark to an element mark about a reference point in a presentation of a structured document comprising: an contract code module which contains instructions to determine a document position of a reference point, determine an existence of said stream mark, and hierarchically contract said stream mark to a largest lower-level element containing said reference point and is contained in said stream mark; a display device for displaying a representation of said structured document, said stream mark and said element mark to a user; a random access memory which provides a temporary storage for said contract code and a database representation of said structured document; and a central processing unit for controlling and coupled to said display device and said random access memory which when executing commands within said contract code module; determine a document position of a reference point in said structured document; determines whether said document position is inside an element which is also contained in said stream mark; and, contract said stream mark a largest element containing said document position and is contained in said stream mark to produce an element mark.

Claim 21

A document processing system capable of hierarchically contracting a stream mark to an element mark about a reference point in a presentation of a structured document comprising: an contract code module which contains instructions to determine a document position of a reference point, determine an existence of said stream mark, and hierarchically contract said stream mark to a largest lower-level element containing said reference point and is contained in said stream mark; a display device for displaying a representation of said structured document, said stream mark and said element mark to a user; a random access memory which provides a temporary storage for said contract code and a database representation of said structured document; and a central processing unit for controlling and coupled to said display device and said random access memory which when executing commands within said contract code module; determine a document position of a reference point in said structured document; determines whether said document position is inside an element which is also contained in said stream mark; and, contract said stream mark a largest element containing said document position and is contained in said stream mark to produce an element mark.
