Ufxtract

Creating format definitions

The parser run off format definition objects. These objects describe the structure of the microformat and the rules to parse it. They are constructed of three object types "UfFormatDescriber", "UfElementDescriber" and "UfAttributeValueDescriber". It worth noting that there are a few generalist rules applied by the parse which are not in definition objects.

You can create your own format definition objects to add new microformat or POSH patterns to UfXtract.
