Question

How to get tag in html page, if I know what text tag contains.
E.g.:

<a ...>SearchingText</a>

Answer 1

You’ll have to traverse by hand.

var aTags = document.getElementsByTagName("a");
var searchText = "SearchingText";
var found;

for (var i = 0; i < aTags.length; i++) {
  if (aTags[i].textContent == searchText) {
    found = aTags[i];
    break;
  }
}

// Use `found`.
