getElementsByTagName

Hi,

I have a set of elements by tag name eg. <img> I want to extract and also identify which one I have taken.

eg.

<a><img src="1.png"/></a>
<a><img src="2.png"/></a>

How do I get 1.png or 2.png .

 var objImages = document.getElementsByTagName('image');  for(var imgIndex =0; imgIndex<=objImages.length-1; imgIndex++)  {      var objImage = objImages[imgIndex];      //add your code here to handle objImage image object ;  }

you should use: document.getElementsByTagName('img') (<image> is not a valid tag name)

:) yes I realise that. It was typo!!!. Obviously there is no such element with nodeName image.

not in html ... :) but in XUL for example it is ... certainly a typo and a good catch too to point that out to avoid confusion ... well done ... both of you ;))
