Hi,

Firstly, you could get the sourcecode with winjs.xhr.

Secondly, you could use regular expressions to get the innerHTML from <body>.

#WinJS.xhr function

Thanks for the reply but my question does not mention where the iFrame loads its content from, so I mean extracting the HTML from the inside of the iFrame. In my case the iFrame loads a local HTML file that was copied inside the private app folders on behalf of the user.

Hi,

Anyway, you need to request the iframe page firstly. And extract the html content later.

To load the page in the iFrame the src attribute has to be set, so xhr is not useful because the page is not requested, it is loaded from disk. I often experienced the DOM document of the iFrame being not accessible when a local html is involved (Chrome, for example).
