[Htmlparser-user] is htmlparser used only once?

[Dave <jav...@ya...>]

Hi,
   
  Parser parser = new Parser();
  parser.setResource(http://web-site);
   
  ...
  NodeList nodes = parser.extractAllNodesThatMatch(filter);
   
  NodeList nodes1 = parser.extractAllNodesThatMatch(filter);
   
  The first call is correct, having the right node list.
  but the second call with the same filter returned null.
   
  I need to use the same parser multiple times without re-parsing the same page. 
  parser.reset() will re-parse the same page. What should I do?
   
  Thanks for help.

Collect everything in a NodeList using parse(null), i.e. no filter.
Then filter the NodeList each time using 
NodeList.extractAllNodesThatMatch().
