Question

I’m trying to make a script to verify if a nodeValue is in the html document

var myVar= document.getElementsByTagName("b");
for (var i = 0; i < myVar.length; i++) {
  var pumpkin = myVar[i].firstChild;  
  if(pumpkin.nodeValue == "Some text")
  {
    alert("exists");
  }
}

It doesn’t work if the text I want to find contains filtered characters like   instead of spaces.
When I’m looking with DOM Inspector those characters are not there (there are normal spaces instead), but when I look page source they are.

I tried

if(pumpkin.nodeValue == "Some text")

and

if(pumpkin.nodeValue == "Some text")

but both failed…
Anyone have an idea?

(it works fine when the text I want to find doesn’t contains these characters in the source code).
thanks in advance

You can do it with help of regular expression because  ‘s corresponding character code is 160

var myVar= document.getElementsByTagName("b");
for (var i = 0; i < myVar.length; i++) {
    var str = myVar[i].firstChild.nodeValue;  
    var re = new RegExp(String.fromCharCode(160), "g");
    if(str.match(re)) alert("exists");
}
