Hello,

I have a script that loops through all the div tags in a page and reads there innerHTML into a array.
the problem i have is i get this error:
Error: uncaught exception: [Exception... "String contains an invalid character" code: "5" nsresult: "0x80530005 (NS_ERROR_DOM_INVALID_CHARACTER_ERR)"]
and its really annoying me the innerHTML is "test test" (without quotations) it errors when it reaches the space i beleive can you help me to know why and how to fix it?

Without some code and HTML to examine, our ability to help you is limited.

oh, ok then
well what i was trying to do was to add an image in after the page has loaded

var attribute="";
var value="";
var mode=0;
for(i=0; i<document.getElementsByTagName("div").length; i+=1) {
 if(document.getElementsByTagName("div").item(i).id=="imagecontainer") {
  var stringarray=document.getElementsByTagName("div").item(i).innerHTML.split("")
  document.getElementsByTagName("div").item(i).innerHTML="<img id='curimage' />";
  for(a=0;a<stringarray.length;a+=1) {
   if(mode=0) {
    if(stringarray[a]==' '){
     mode=1;
    } else {
     attribute=attribute+stringarray[a];    
    }
   } else {
    if(stringarray[a]==" ") {
     document.getElementById("curimage").setAttribute(attribute,value);
     mode=0;
     attribute=""
     value=""
    } else {
     value+=stringarray[a];
    }
   }
  }
 document.getElementById("curimage").removeAttribute("id");
 }
}

and the div tag is like this:

<div id="imagecontainer">test test</div>

check out this line:

if(mode=0) {

You must mean:

if(mode==0) {

Although the first example is still valid, it will always return true, which is not your intention I can tell.

I dont know how i made such an error, and didn't see it.

Very common error actually, but sometimes all it takes is a fresh pair of eyes to spot it.
