Abstract
The present invention relates to systems and methods for parsing of a token stream for user generated content in order to prevent attacks on the user generated content. The systems and methods include a database which stores one or more whitelists, and a parser. The parser removes tokens from the token stream by comparing the tokens against the whitelist. Next, the parser validates CSS property values, encodes data within attribute values and text nodes, reconciles closing HTML tags, and coerces media tags into safe variants. The tokens removed may be any of HTML tags, HTML attributes, HTML protocols, CSS selectors and CSS properties.
