Php screen scraping using php simple dom parser

Question

I am using simple html dom parser to scrape a website ... How can i skip a particular class while in a loop

Suggested third party alternatives to SimpleHtmlDom that actually use DOM instead of String Parsing: phpQuery, Zend_Dom, QueryPath and FluentDom. — Gordon

Judging from http://simplehtmldom.sourceforge.net/manual.htm#frag_find_attr you can use:

->find("div[class!=skip_me]")

Or use the DOM methods and check with ->getAttribute("class") against a value.

  // DOM can load HTML soup. But, HTML soup can throw warnings, suppress
  // them.
  $htmlDom = new DOMDocument();
  @$htmlDom->loadHTML($html);
  if ($htmlDom) {
    // It's much easier to work with simplexml than DOM, luckily enough
    // we can just simply import our DOM tree.
    $elements = simplexml_import_dom($htmlDom);

This is a quote (almost) from Drupal 7 SimpleTest. After this, it's a lot easier work with the document, the class can be reach as $element['class']

The correct way to suppress parsing errors is to use libxml_use_internal_errors() and then clear them with libxml_clear_errors(). If you use the Error Suppression Operator it will suppress any error, not just the parsing errors.
