Technique for creating and expanding 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 expanding 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 an element which also contains all of said structured document contained in said stream mark; expanding said stream mark to mark a smallest element containing said reference point and said corresponding portion of said structured document to produce an element mark; and displaying said structured document on said display device emphasizing said element mark.

Claim 3

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

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 i claim 1, which further comprises the step 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: expanding said element mark to a second smallest element containing the current document position and said smallest element to produce a parent element mark; and displaying said structured document ons aid display device emphasizing said parent element 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 a second smallest element which also contains all of said smallest element; expanding said element mark to a second smallest element containing the current document position and said smallest element to produce a higher level mark; and displaying said structured document on said display device emphasizing said higher level mark.

Claim 10

In a document processing system including a central processing unit, a random access memory device and a display device, a method for hierarchically expanding an element mark which marks an element 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; expanding said element mark to a parent element of said element to produce a parent element mark; and displaying said structured document on said display device emphasizing said parent element mark.

Claim 11

In a document processing system including a central processing unit, a random access memory device and a display device, a method for hierarchically expanding an element mark which marks an element 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; expanding said element mark to a parent element of said element to produce a parent element mark; and displaying said structured document on said display device emphasizing said parent element mark.

Claim 12

The method as recited in claim 9, wherein said reference point is the current document position.

Claim 13

The method as recited in claim 9, wherein said structured document is in SGML format.

Claim 14

The method as recited in claim 9, wherein said method is invoked by a single user action.

Claim 15

The method as recited in claim 9, which further comprises the step of an additional editing operation on said parent element.

Claim 16

The method as recited in claim 9, wherein said structured document is displayed to the suer i a WYSIWYG representation.

Claim 17

The method as recited in claim 9, which further comprises the step of: expanding said parent mark to a parent element of said parent element to produce a grandparent element mark; and displaying said structured document on said display device emphasizing said grandparent element mark.

Claim 18

The method as recited in claim 9, which further comprises the steps of: moving said reference point within said structured document; determining a smallest higher level element which contains said reference point and said parent element; expanding said parent element mark to the smallest higher level element containing the current document position and said parent element to produce a higher level element mark; and, displaying said structured document on said display device emphasizing said higher level element mark.

Claim 19

A document processing system capable of hierarchically expanding a stream mark to an element mark about a reference point in a presentation of a structured document comprising: an expand code module which contains instructions to determine the document position of a reference point, determine the existence of said stream mark, and hierarchically expand said stream mark to a smallest higher-level element containing both said reference point and said stream mark; a display device for displaying a representation of said structured document, said stream mark and said element mark to a suer; a random access memory which provides a temporary storage for said expand 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 expand code module; determines a document position of a reference point in said structured document; determines whether said document position is inside an element which also contains all of said structured document which corresponds to said stream mark; and, expands said stream mark to mark a smallest element containing said document position and said corresponding portion of said structured document to produce an element mark.

Claim 20

A document processing system capable of hierarchically expanding a stream mark to an element mark about a reference point in a presentation of a structured document comprising: an expand code module which contains instructions to determine the document position of a reference point, determine the existence of said stream mark, and hierarchically expand said stream mark to a smallest higher-level element containing both said reference point and said stream mark; a display device for displaying a representation of said structured document, said stream mark and said element mark to a suer; a random access memory which provides a temporary storage for said expand 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 expand code module; determines a document position of a reference point in said structured document; determines whether said document position is inside an element which also contains all of said structured document which corresponds to said stream mark; and, expands said stream mark to mark a smallest element containing said document position and said corresponding portion of said structured document to produce an element mark.

Claim 21

The document processing system as recited in claim 17, which further comprises: a printer for producing a hard copy of said structured document coupled to said central processing unit; a read only memory for storing fixed operation instructions coupled to and executed by said central processing unit; and disk storage for permanent storage of said expand code modules coupled to said central processing unit.
