regex - selenium: Is it possible to use the regexp in selenium locators

Question

I want to get the xpath count of all the divs/links/.. that have text matching some regular expression. For example:

<span> day 2 night </span>
<span> day 4 night </span>
<span> day 17 night</span>

I would like to be able to call:

sel.get_xpath_count('regexp:day d night')

and have it return 2. (This is a simple example of course, I would like to use all kinds of regular expressions)

Is this possible, and how to do it?

Answer 1

Use the dom= protocol which allows you to use javascript. And javascript has regexp:

# sorry, example in Perl:
$sel->get(qq{dom=(function(){
    var x = document.getElementsByTagName('span');
    var result = [];
    for (var i=0;i<x.length;i++) {
        var txt = x[i].innerHTML;
        if (txt.match(/day d night/)) {
            result.push(x[i]);
        }
    }
    return result;
})()});
