Re: [Htmlparser-user] HTML parser for HTML translation

[Aminudin K. <ami...@mi...>]

Hi,

You're right, HTMLVisitor does exist in  htmlparser.jar .  Many strange 
things happened during compilation but I've  managed  to reduce some errors.

Could u guys help me analyzing what is wrong in the following codes.  In 
HTMParser there is a method called *visitAllNodesWith(visitor)* . The 
argument's  type is *HTMLVisitor.  *However, the following class use 
StringTranslatingVisitor which extends HTMLVisitor as an argument. JAVAC 
keeps complaining me about this.

Your help is appreciated. Thanks

p/s :  Notice that I've commented out  "import org.htmlparser.visitors". 
I couldn't compile if I include this line. (Any reason/ idea ?)
            FYI, my development platform is Linux.
