Method and apparatus for dynamically adding functionality to a set of instructions for processing a Web document based on information contained in the Web document

A computer-readable medium having stored thereon a first set of instructions, said first set of instructions provided for processing a Web document, said first set of instructions, which, when executed by a processor, cause said processor to perform the steps of:

• decoding by said first set of instructions a first statement provided by said Web document, said first statement including a first command and at least one instruction provided as an argument to said first command;
• issuing by said first set of instructions said first command provided by said Web document to be executed;
• in response to an execution of said first command, decoding by said first set of instructions said one instruction provided as said argument to said command and issuing said one instruction to be executed;
• and
• providing new Web document processing functionality to said first set of instructions upon execution of said one instruction provided by said first statement of said Web document.

A computer system comprising of:

• a first mechanism to process a Web document, said first mechanism operable to decode a first statement provided by said Web document, said first statement including a first command and at least one instruction provided as an argument to said first command;
• said first mechanism operable to issue said first command provided by said Web document to a processor to be executed;
• and
• said first mechanism operable to decode, in response to an execution of said first command, said one instruction provided as said argument to said command and issue said one instruction to be executed, wherein execution of said one instruction provides new Web document processing functionality to said first mechanism.

A machine-implemented method comprising the steps of:

• receiving a Web document, the Web document providing information indicating a new functionality for processing the Web document;
• executing a set of instructions to process the document, the set of instructions including a set of one or more commands that provide functionality for processing the Web document;
• the set of instructions processing the information provided by the Web document, which information indicates the new functionality for processing the Web document;
• and
• in response to processing the information provided by the Web document for indicating the new functionality for processing the Web document, altering the set of one or more commands of the set of instructions to include a new command for providing the new functionality to the set of instructions for processing the Web document.
