}
}
if(!this.canHaveChildren){
return str " />";
}
return str ">" this.innerHTML " ";
});
pro.__defineSetter__("outerHTML", function(s){
var r = this.ownerDocument.createRange();
r.setStartBefore(this);
var df = r.createContextualFragment(s);
this.parentNode.replaceChild(df, this);
return s;
});
pro.__defineGetter__("canHaveChildren", function(){
return !/^(area|base|basefont|col|frame|hr|img|br|input|isindex|link|meta|param)$/.test (this.tagName.toLowerCase());
});
