getParser

public static Parser getParser(String contentType,
                               String url)
                        throws ParserNotFound

Returns the appropriate Parser implementation given a content type and url.

Parser extensions should define the attributes"contentType" and/or "pathSuffix". Content type has priority: the first plugin found whose "contentType" attribute matches the beginning of the content's type is used. If none match, then the first whose "pathSuffix" attribute matches the end of the url's path is used. If neither of these match, then the first plugin whose "pathSuffix" is the empty string is used.

Throws:

ParserNotFound
