Regarding Text And Pattern Matching

[Shuvadeep Lahiri]

Hello everybody,
      I am new to HTMLParser. I am trying to parse a page which has a <tr> tag as follows :
     <tr> Translation
         <td>First : <a href="http://www.freetranslation.com" > </a></td>
        

      </tr> 
Now I  have been able to pick up all the <tr> from a Table. My code is as the following :

  public class  TestParse
{
    public static void main(String[] args)
    {
          
        try{

                       Parser parser = new Parser("file:///E:/HTMLParser/test/a2.htm"); 
              String [] tagsToBeFound = {"table"};
              TagFindingVisitor visitor = new TagFindingVisitor(tagsToBeFound);
              parser.visitAllNodesWith(visitor);
              Node [] alltableTags = visitor.getTags(0);
               Lexer lex=new Lexer(alltableTags[0].toHtml());
              Parser newparse=new Parser(lex);
                         NodeList list = newparse.extractAllNodesThatMatch(new AndFilter(new TagNameFilter("TR")));             

           }
          catch(ParserException e) 
          { 
                System.out.println("Parsing error "+e);
          }
   

    }

}

   I have been able to pick up  all the <tr> tag from the first table and store them up in NodeList list.
      But how could I print only those <tr> which has "Translation" in it's text?
        Could anybody help me out?

It should be something like:
  NodeList list = newparse.extractAllNodesThatMatch (
    new AndFilter (
        new TagNameFilter ("TR")
        new HasChildFilter (
            new StringFilter ("Translation", false)
            true)));

You can use the FilterBuilder application to create and test out filters you construct graphically:
    bin/filterbuilder
see http://sourceforge.net/project/screenshots.php?group_id=24399 for a screenshot. It has a help and a tutorial that covers most everything you can do with it. When you 'Save As' it creates a java file for you.

Thanks. It works. I am studying FilterBuilder and post further query as and when needed. Thank you very much once again.
