[JS] getElementsByHrc()

[Schubaltz]

I got the idea from my forElements...do snippet. If you can do a search on that scale with that script, why limit it?

Description: Takes getElementsByAttr() a bit further, allowing you to check for childNodes and attributes of childNodes.

Syntax: getElementsByHrc(string, {,attributes})

function getElementsByHrc(a, b) {
      var n = [];
      for(var i = document.getElementsByTagName(a), x = 0; x < i.length; x ++)
            if(forHierarchy(i[x], a))
                  n.push(i[x]);
      return n;
}
function forHierarchy(a, b) {
      for(var x in b)
            if(a[x] && b[x].constructor == Object) {
                  if(!this.forHierarchy(a[x], b[x]))
                  return false;
            } else if((b[x].constructor == RegExp ? !a[x].match(b[x]) : a[x] != b[x]))
                  return false;
      return true;
}

Example:
var i = getElementsByHrc("td", { className: "catbg", firstChild: { nodeName: "B" })
for(var x = 0; x < i.length; x ++)
      i[x].innerHTML += "lol";

The above will insert the text "lol" into any TD elements with classNames of "catbg" and firstChilds with nodeNames of B.
