Re: [Htmlparser-user] Only extract text from div tag with specific attribute

[Joshua K. <jo...@in...>]

You'll want to write your very own Visitor.

Something like this (I'm using an older version of htmlparser for this
example):

public class DivVisitor extends NodeVisitor {

    public void visitTag(Tag tag) {
       // see if the tag is a div tag here and then check its attibutes
      // if it matches what you want, collect it into something that this
visitor can return via some getter method
    }
}

Send your DivVisitor into the parser as you were doing with the
ObjectFIndingVisitor.

Hope that helps,
jk
