Question

Is there a way to create a java script function that on page load counts amount of times this pattern appears in html code? "</b> <li>"(with one space in the middle between the </b> and <li> ) Would it be a dom element?

Thanks

Answer 1

document.body.innerHTML.match(/<\/b>\s<li>/g).length

Edit: as @Laas’ answer hints, the solution above does not handle 0 nicely because match returns null rather than []. To fix that, use his answer, or this (which is equivalent):

function countPattern()
{
    var matches = document.body.innerHTML.match(/<\/b>\s<li>/g);
    return matches ? matches.length : 0;
}
