Reachability Analysis of the HTML5 Parser Specification and Its Application to Compatibility Testing

A draft standard for HTML, HTML5, includes the detailed specification of the parsing algorithm for HTML5 documents, including error handling. In this paper, we develop a reachability analyzer for the parsing specification of HTML5 and automatically generate HTML documents to test compatibilities of Web browsers. The set of HTML documents are extracted using our reachability analysis of the statements in the specification. This analysis is based on a translation of the specification to a conditional pushdown system and on a new algorithm for the reachability analysis of conditional pushdown systems.
