I want to write something of the sort: //a[not contains(@id, 'xx')] (meaning all the links that there 'id' attribute doesn't contain the string 'xx') I can't find the right syntax. not() is a function in xpath (as opposed to an operator), so //a[not(contains(@id, 'xx'))] you can use not(expression) function or expression != true() None of these answers worked for me for python. I solved by this a[not(@id='XX')] Also you can use or condition in your xpath by | operator. Such as a[not(@id='XX')]|a[not(@class='YY')] Sometimes we want element which has no class. So you can do like a[not(@class)]
