Hi Everyone,

I know that there is a few post already on row removal but have read and tried what they are saying but having no luck. But it may be because I am new.

Anyway what I am trying to do is remove the third row of a table.
The xpath /html/body/table/tbody/tr[3]
The HTML code is

 
< body id="slam">
   < table id="jam">
     <tbody>
       <tr>  1  </tr>
       <tr>  2  </tr>
       <tr>  3  </tr>
     </tbody>
   < /table>

what I have tried is

document.getElementsById('slam').getElementsById('jam').getElementsByTagName(tbody).removeChild(rowset[3]);

and

document.evaluate('//table/tbody/tr[3]',document,null,XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,null).style.display = 'none';

Any help would be greatly appreciated.

It's getElementById with no "s" in it. It returns exactly one DOM element. Then you spelled getElementsByTagName correctly, but the parameter is supposed to be a string "tbody" and it returns a collection of DOM elements. If you want to address a specific one (e.g. the first) you'll have to use a proper index on the collection

var theParent = document.getElementById('jam').getElementsByTagName('tbody')[0];
theParent.removeChild(theParent.getElementsByTagName('tr')[2]);

For what it's worth, a table also has a rows collection. If there are no rows in a <thead> element, then you should be able to remove the third row in the table's rows collection like this:

rowToDelete = document.getElementById("jam").rows[2];
rowToDelete.parentNode.removeChild(rowToDelete);

Thanks devnull69 for pointing out the 's' also got it working by

 document.getElementById("jam").deleteRow(2); 

Thanks to Monkey2000 point out can just use the table's id

Thanks both for the help
