An anchoring method for generating an XPath expression. The method can include identifying a stable anchor in the transcodable markup along an axis shared by the selected node. An XPath expression can be generated for the stable anchor. Subsequently, an offset between the stable anchor and the selected node can be computed. Finally, the XPath expression for the stable anchor and the offset can be concatenated, the concatenation forming the XPath expression for the selected node.

A broadcast system includes a transmitting unit configured for: receiving a web page as input; converting the web page into video image data; and providing a link to the video image data on a basis of a link provided to the web page; an encoder for compressing the video image data; and a receiving unit for receiving the compressed video data; decoding the compressed video data; and directly transmitting the decoded video data to a video display device, without requiring a browser application.

Broadcasting for browsing the web

A method and system for applying a method for iterative refinement of a presentation including (a) a developer creating a high-level representation of the user interface; (b) automatically generating a concrete user interface markup from the high-level representation; (c) the developer editing the concrete generated markup and saving the edits to an edit history; (d) the developer editing the high-level representation; (e) automatically re-generating a concrete markup from the edited high-level representation; and (f) automatically or interactively applying the edit history to the concrete markup to produce an updated markup.

Methods, apparatus and systems to keep a desired element properly addressed in a structured document in which particular elements are addressed, even if the structured document is modified. In an example embodiment, the invention comprises a difference computation unit for computing a difference between structured documents, and an XPath update unit for generating addressing information from addressing information that addresses a part of a particular structured document based on information on the difference computed by the difference computation unit, the generated addressing information addressing a corresponding part of the other structured document.

Data processing and difference computation for generating addressing information

The present invention provides a method and apparatus to browse the Web without using a web browser. The application server in a transmitting unit converts a web page transmitted from the Internet into video data and provides links to the video data on the basis of the links provided to the web page. In the video server of the transmitting unit, the video data transmitted from the server is compressed by the MPEG2 encoders, and sent with information about the links provided to the video data. A 'Set-Top Box', of the receiving terminal outputs the received video data to a display, and establishes an association between the links provided to the video data and a position of a cursor displayed on the screen of the display.

Broadcast system and method for browsing the web

A system, method, and computer program product for generating a web application, including objects and web pages dynamically generated on a server, which can be used to generate a web application model to support a change or reconstruction of the system. A classification processing section analyzes and classifies the configuration of static HTML contents captured by executing a web application. A template extracting section extracts a template for dynamic HTML contents from the web application using the results of the classification. On the basis of the results of the classification by the classification processing section and access information obtained by capturing the static HTML contents, a transition extracting section extracts transition information on the web application to be processed. Then, on the basis of the extracted template and transition information, model generating means renders an HTML document generating a model of the web application, to generate an image.

A method and system for generating robust XPath expressions for a selected node in transcodable markup. The system of the invention can include a set of differing XPath expression generators; an interface through which at least one of the XPath expression generators can be selected; and, an XPath generator processor configured to apply each of the selected XPath expression generators to the selected node in the transcodable markup to produce a redundant set of robust XPath expressions configured to identify the selected node. Notably, the system also can include an XPath resolution processor. The XPath resolution processor can resolve each XPath expression in the redundant set. The resolutions, in turn, can identify a set of candidate nodes, the XPath resolution processor identifying the selected node from among the set of candidate nodes based upon the XPath expressions resolving to the selected node more than any other node in the set of candidate nodes.

Selectable methods for generating robust XPath expressions

A structure pattern candidate generating system is disclosed for automatically generating many kinds of complicated structure pattern candidates and facilitating selection of a structure pattern suitable for the purpose. When the system is provided with a structure pattern pointing to an element or an element set in a document logical structure of a structured document, that has been specified by a user, a method for determining an item to be edited determines an item to be edited among the items composing the structure pattern. A method for generating structure pattern candidates replaces the item to be edited with items in different expressions based on the document logical structure information about the structured document to generate structure pattern candidates. A method for generating a structure pattern candidate list arranges the generated structure pattern candidates based on a condition and index for display for giving selection criteria to the user to generate a structure pattern candidate list. If the system is provided with an item desired to be edited, that has been specified by the user for the structure pattern, the method for determining an item to be edited determines the item desired to be edited as the item to be edited.
