Methods and systems of outputting content of interest

A computer program product comprising a computer program stored on a computer-readable medium, the computer program comprising instructions which when executed by computer or distributed computer system having a processor and memory cause the computer or distributed computer system to carry out:

• loading a common expression and a data structure definition into memory, the common expression identifying a content element in a first structured electronic document, the data structure definition defined according to the common expression;
• creating in memory an instance of a data structure defined by the data structure definition;
• applying with the processor the common expression to a second structured electronic document to extract a content element from the second structured electronic document;
• storing the extracted content element in the instance of the data structure;
• and
• populating a template structured electronic document using the instance of the data structure to produce an output structured electronic document.

A computer or distributed computer system, the computer or distributed computer system comprising:

• a computer program and memory on which the computer program is stored,
• a processor executing in accordance with the stored computer program,
• wherein the computer program comprises instructions which when executed by the computer or distributed computer system cause the computer or distributed computer system to carry out:
• loading a common expression and a data structure definition into memory, the common expression identifying a content element in a first structured electronic document, the data structure definition defined according to the common expression;
• creating in memory an instance of a data structure defined by the data structure definition;
• applying with the processor the common expression to a second structured electronic document to extract a content element from the second structured electronic document;
• storing the extracted content element in the instance of the data structure;
