Re^7: WWW::Mechanize::Firefox and dynamic pages

Does it matter that the link I'm trying to capture from the page with my script resides inside of an iframe? It looks like this in firebug:

<iframe id="iframe_canvas" class="smart_sizing_iframe" scrolling="yes"
+ height="800" frameborder="0" msallowfullscreen="" oallowfullscreen="
+" mozallowfullscreen="" webkitallowfullscreen="" src="javascript:""" 
+name="iframe_canvas_fb_https" style="height: 472px;">
<html>
<head>
<body>
<div>
<a href="link I'm trying to capture"</a>
</div>
</body>
</head>
</html>
</iframe>

I already have this in my perl code:

$mech->allow(plugins => 1, javascript => 1, metaredirects => 1, frames
+ => 1, subframes => 1, images => 1);
[download]

So it seems like all iframes should be processed correctly, right?

Yes, it does matter. `->content` never looks inside `iframe` elements.	[reply] [d/l] [select]

Is there a way to make `content()` look into frames? I added this to my code: `my @frames = $mech->expand_frames(); my $frame_ctr = 0; for ($frame_ctr = 0; $frame_ctr < @frames; $frame_ctr++) { printf("frames[%s] = %s\n", $frame_ctr, $frames[$frame_ctr]); }` [download] But I'm not really sure what to do with the frames that were returned.

What you get back are DOM nodes. You can access their attributes. For example, the `innerHTML` attribute: `print $frame->{innerHTML}` [download] By doing that, you've mostly left the area that WWW::Mechanize::Firefox supports and you will have to consult the Firefox documentation for what attributes and methods are supported.

Just because I hate finding questions online with no resolution, I'm coming back with the answer. Here is how I was able to find the link I was looking for within the page's HTML: `my @test_frames = $mech->xpath('/html/body/div/p/a', one => 1, frames +=> 1); printf(TEST_FH "result is %s\n", $test_frames[0]->{outerHTML});` [download] I obtained the xpath using Firebug (highlight the link on the webpage, right click, select "copy Xpath") then used the outerHTML (as opposed to innerHTML) to get the URL.
