This piece of code can not select all text inside of a div. Say, there are several span tags in a div. The code selects only the first tag (in my case, this was the first line). Solved it already! I changed line 11. Instead of 1 in the last parameter, I computed the number of children inside the div and it worked. Please enhance the code sometime :)
