[Htmlparser-user] How to save <TD> value to unique variables from html tables

[Henry T. <htr...@ya...>]

Hi All,
I have been successful in extracting almost all the table data using the following htmlparser statements in Java:
Parser parser = new Parser ("http://www.abc.com/...");          
           NodeList nl = parser.parse(null);
           NodeFilter currenttabledatafilter =
                   new AndFilter (
                       new TagNameFilter ("td"),
                       new OrFilter (
                           new HasAttributeFilter("class","even"),
                           new OrFilter (
                               new HasAttributeFilter("class", "odd"),
                               new AndFilter (
                                   new HasAttributeFilter("colspan","6"),
                                   new HasChildFilter(new TagNameFilter ("Strong"))))));
           NodeList a1 = nl.extractAllNodesThatMatch(currenttabledatafilter,true);
           int len = a1.size();
           for (int i=0; i<len; i+=1)
           {
               TagNode tag = (TagNode)a1.elementAt(i);
               System.out.println(tag.toPlainTextString());
//             System.out.println(tag.toHtml());
           }
       } catch(Exception pe) {
           pe.printStackTrace();
       }
This is great for retrieving all these table data. However, I would like to save the value of each <td> to a unique variable so that they could be used in the program and ultimately save them to database. As a result, I am looking to structure a program to assign  each value to a unique variable (or insert it into the database, which I can do once they are available) from as many html tables on a web page. Each table has some distinct attributes but varies on the number of <td> in them. In other, I am looking for some thing similar to the loop through a text a file as follows:
While not end of line
(i) identify a new table based on its unique attributes.
(ii) assign the value/content of each <td> in the current table to a unique variable for instance.
(iii) repeat step (i) and (ii) for remaining tables.
Thanks a lot,
Henry
