Method and apparatus for stream based markup language post-processing

A method for processing markup language data, the method comprising:

• receiving a markup processing program containing a set of markup processing instructions that, when executed in an embedded hardware markup post-processing device, carry out application of one or more expressions on streaming data represented by a markup language representation, each markup processing instruction including an operation defining a processing operation to be matched to the markup language representation and a corresponding action to be performed upon matching the operation to the markup language representation;
• receiving the markup language representation containing encoded items representative of markup language constructs;
• and
• executing the markup processing program, in real-time, in hardware to the streaming data in conjunction with the markup language representation to dynamically control generation of an output control signal indicating how the markup language representation is to be processed for generation of output based on the markup language representation;
• wherein receiving the markup language representation containing encoded items representative of markup language constructs comprises:
• receiving a stream of encoded items containing type, length, value (TLV) representations of extensible markup language constructs within the markup language representation, at least some of the encoded items containing values that are value references usable as index data values into the instruction reference information configured within the indexed memory to identify successive markup processing instructions to be executed wherein executing the markup processing program comprises:
• identifying markup processing instructions of the markup processing program that match encoded items of the markup language representation;
• and
• for each markup processing instruction containing an operation that matches an encoded item of the markup language representation, performing the operation included in that markup language instruction to produce an operation outcome;
• and
• if the operation outcome indicates that performance of the operation is successful, applying the action on the markup language representation to produce the output control signal indicating how the markup language representation is to be processed for generation of output based on the markup language representation wherein applying the action on the markup language representation to produce the output control signal comprises:
• providing an output control signal to an output generator to indicate a type of output to provide from a markup processing device wherein providing an output control signal to an output generator to indicate a type of markup language representation to output from a markup processing device comprises:
• configuring the output control signal to indicate to the output generator to produce encoded item output for at least one encoded item that correspond to execution of the markup language program upon the received markup language representation.

• wherein providing an output control signal to an output generator to indicate a type of markup language representation to output from a markup processing device comprises:
• adjusting a value of a counter associated with the output control signal based on execution of the markup language program upon the received markup language representation.
