walking dom - iframe

[carlos]

When I use firebug or IE developer to step through the dom, I can't
seem to view the iframe's src page childreNode elements. What I want
to be able to do is walk the dom, and when I get to an iframe element,
go through the src page's children. So for an element named <iframe
id='myFrame' src='myPage.html' />, I want to step through myPage.htm's
childNode elements. Does anyone know if this can be done, and if so,
do they know of an example?

Thanks

There is no page. However, you should look at (and into) the
`contentWindow' and `contentDocument' properties of the element objects, the
latter defined in W3C DOM Level 2 HTML (HTMLObjectElement, HTMLFrameElement
and HTMLIFrameElement interfaces):

http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-38538621
http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-78799536
http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-67133006

Gecko-based user agents support both properties for `frame' and `iframe'
element nodes, and the second one for `object' element nodes:

Apparently version 5.5+ of the MSHTML DOM (I have only the standalone
versions to test with 6.0 and before) supports only the first property:

The IE Developer Toolbar (if that is what you meant) is inferior to Firebug
also in the regard that it displays neither property even if supported.
