Automatic targeting of browser content to optimal rendering engine

A content browsing data processing system comprising:

• a host computer with processor and memory;
• a content browser executing in the memory by the processor of the host computer;
• a plurality of different rendering engines coupled to the content browser;
• and,
• a target rendering engine selection module coupled to the content browser, the module comprising program code that when executed by the processor of the host computer maps to a target one of the different rendering engines at least one directive embedded in content retrieved by the content browser, selects the target one of the different rendering engines for rendering the content and passes the content to the selected target one of the different rendering engines;
• wherein each of a plurality of directives embedded in the retrieved content is mapped to one of a selection of different target rendering engines, each of the mapped directives is rated according to a severity of incompatibility with a target rendering engine that differs from a mapped one of the different target rendering engines, each instance of a mapped one of the target rendering engines is weighted by a rating applied to a corresponding one of the directives, and the weighted instances for each mapped one of the target rendering engines are combined;
• and,
• wherein a target rendering engine for rendering the content is selected corresponding to a greatest combination of weighted instances of mapped ones of the different target rendering engines.

A computer program product comprising a computer usable memory embodying computer usable program code for content driven selection of a rendering engine, the computer program product comprising:

• computer usable program code for retrieving content for display in a content browser executing in memory by a processor of a host computer;
• computer usable program code for mapping at least one directive embedded in the retrieved content to a target rendering engine;
• computer usable program code for selecting the target rendering engine for rendering the content;
• and,
• computer usable program code for passing the content to the selected target rendering engine;
• wherein the computer usable program code for mapping at least one directive embedded in the retrieved content to a target rendering engine, comprises computer usable program code for mapping a plurality of directives embedded in the retrieved content each to one of a selection of different target rendering engines, rating each of the mapped directives according to a severity of incompatibility with a target rendering engine that differs from a mapped one of the different target rendering engines, weighting each instance of a mapped one of the target rendering engines by a rating applied to a corresponding one of the directives, and combining the weighted instances for each mapped one of the target rendering engines;
• and,
• wherein the computer usable program code for selecting the target rendering engine for rendering the content, comprises computer usable program code for selecting a target rendering engine for rendering the content corresponding to a greatest combination of weighted instances of mapped ones of the different target rendering engines.
