Reading HTML in frame

[Chip]

Here's the problem: I need to look up records from Library of Congress and
associate the data to a book in my database.

Here's how I think it should work. Open the Library of Congress search page
in a frame within my app. Do your searching and select a record. Now click a
button on the "my app" frame to import that record.

I should be able to read the HTML in one of two ways:
Access the buffer in the other frame
Get the URL from the other frame and access the page through more
conventional means

I would prefer to just read a buffer since I've already accessed the page.
Can somebody help with some pointers to how I can read the HTML in a frame?

Thanks,
Chip

How will you import it? If its in a frame, it will be in the users browser.
JS might get it - but often different windows and frames that are from
different domains are security blocked.

Access the buffer in the other frame

Maybe? Might be security restrictions.

Get the URL from the other frame and access the page through more
conventional means

By refetching on to the server?

You will have to use Javascript - if the security model will let you because
its a different domain.

Thanks for the reality check -- of course the buffer is in the browser and
not the server.
Is there any way to capture the URL of the page the user has open in this
frame?

I *think* you might be able to read the URL. But then again, maybe not
because URLs often contain sensitive info that could be used by a hacker.
You'll need to look at the JS security model as well as try it out.
