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

[Jumbo P. <jum...@gm...>]

I figured it out.  It's actually pretty simple.  Here is the code.  Thanks
anyway.

Parser p = new Parser(url);
NodeList list = p.extractAllNodesThatMatch (new AndFilter (new TagNameFilter
("div"), new HasAttributeFilter("class", "body")));
StringBean sb = new StringBean();
list.visitAllNodesWith(sb);
System.out.println(sb.getStrings());
