Re: [Htmlparser-user] Parser inserts extra characters in Javascript

[Dave L. <la...@da...>]

I ran into the same issue. It turns out that having '<' characters in the
script character data is illegal (but very common).  There is a global flag
at org.htmlparser.scanners.ScriptScanner.STRICT which defaults to true.  Set
it to false, and it will accept more of the common illegal javascript,
though it still has problems on combinations of quotes, commments, and '<'
characters.  If you run into them, you'll need to override the Lexer
yourself and modify the parseCDATA(boolean) method.

Good luck.
