Abstract

Handheld display devices have often limited display capabilities. In order to view a full HTML page (200), a method is provided that splits the original page into less complex units (210, 206, 208, 204, 212, 214, 202) so that they can be best displayed on these small devices. The document is parsed into a tree structure and the complexity of the tree is calculated. Depending on the complexity it is decided which part of the document must be displayed onto a new page.

Claims

1. Method of displaying a structured document comprising the steps of:

loading the structured document;

parsing the structured document into a hierarchical structure characterized in that the method further comprises the steps of;

calculating a complexity of the hierarchical structure;

traversing the hierarchical structure; and

conditionally displaying a part of the structured document depending on the complexity of a traversed part of the hierarchical structure.

2. Method of displaying a structured document comprising according to claim 1, wherein the complexity is compared with a predetermined threshold to determine a first part of the document to be displayed on a first page and a second part of the document to be displayed on a next page.

3. Method of displaying a structured document comprising according to claim 2, the method further comprising adding a reference to the first page to enable navigation to the second part of the document.

4. Method of displaying a structured document according to claim 1, wherein the document comprises elements that contribute to the hierarchical structure and a property of each element is used to calculate the complexity of the hierarchical structure.

6. Computer program product comprising program code means designed to perform the method according to claim 1.

7. Storage device comprising the computer program product according to claim 6.

5. System to display a structured document, the system comprising:

loading means conceived to load the structured document;

parsing means conceived to parse the structured document into a hierarchical structure

characterized in that the system further comprises;

calculating means conceived to calculate a complexity of the hierarchical structure;

traversing means conceived to traverse the hierarchical structure; and

displaying means conceived to conditionally display a part of the structured document depending on the complexity of a traversed part of the hierarchical structure.
