Member Function Documentation

Starts a new document. Filters should clear their state in this function, as the same Filter instance may be used for multiple HTML documents.

Reimplemented from net_instaweb::EmptyHtmlFilter.

When an HTML element is encountered during parsing, each filter's StartElement method is called. The HtmlElement lives for the entire duration of the document.

Todo:
TODO(jmarantz): consider passing handles rather than pointers and reference-counting them instead to save memory on long documents.

Reimplemented from net_instaweb::EmptyHtmlFilter.
