Thank you MorningZ, I seem to have managed to solve the problem, but I'd like to know whether in Attribute Filters I could use more tha once the same operator. For exemple: to have two or more times the operator ^= to select certain elements that iniciate with different IDs.
Perhaps that is possible and I'm not doing the right way. Example: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <script type="text/javascript" src="js/jquery/jquery.js"></script> <script type="text/javascript"> $(document).ready(function(){ var ElementsArray = $("#MyTable tr[id^='Row'][id^='Line'] [id!='LineEmpty'][id!='RowHeader']"); ElementsArray.each(function(i){ alert($(this).text()); }) }); </script> </head> <body> <table id="MyTable"> <tr id="RowHeader"> <td>Col1</td> <td>Col2</td> </tr> <tr id="Row1"> <td>A1</td> <td>B1</td> </tr> <tr id="Row2"> <td>A2</td> <td>B2</td> </tr> <tr id="Line3"> <td>A3</td> <td>B3</td> </tr> <tr id="Line4"> <td>A4</td> <td>B4</td> </tr> <tr id="LineEmpty"> <td>xx</td> <td>yy</td> </tr> </table> </body> </html> -- Thank you.
