Results

Child Elements and Attributes The most typical result set expresses the fragmented content as elements or attributes for further processing as structured content. (You can also specify default attributes on created elements, xsi:type for instance.)
Skipping There may be times when content should simply be excised. Regular fragmentations permits the skipping of content to make this easier.
Characters Sometimes content may be converted into either a different content (with text added or deleted), or the developer may want to create mixed content. Regular fragmentations permits the expression of results as characters to make this easy.
Before and After There may also be times where developers wish to either add textual content before a result or after. Labelling Year/Month/Day for human consumption may be appropriate in some cases. This is supported by the before and after attributes on the rule descriptions. (Elements may also specify text to be added before and after the content but inside the element.)
Ordering I haven't yet implemented this, but I'm contemplating ways to re-order the results of the regular expression processing.
