Hi, I am approaching to SWT because I saw there is the package
org.eclipse.swt.browser.Browser which lets me embed a browser (IE or Moz)
in my client side app. That is fine (great job) but I am wondering if and
how I can do these 2 things:

1) assuming the browser component loaded a web page
(browser.setUrl("www.something.somewhere") ), how can I access the raw
content of that loaded page? I tought I could have found a method such
browser.getText(), that is the "dual" method of browser.setText(String
html), but I don't see it (swt 3.1M6)

2) I would like to pre-process the pages before they are rendered by the
browser, modifying the DOM a bit to suit my needs: how can I "hook" myself
between the fetch-the-page step and the render-the-page step of the
browser??

thanks,
Alessio Pace.

Hi.

I don't think there's a simple way of doing what you want unless you use
a web server. I suggest an embedded web server like Jetty
(http://jetty.mortbay.org/jetty/) - it's easy to setup and use. With an
embedded server (or servlet) you can do all the capturing and
pre-processing of the data you want.

Why not load it directly from the URL ?

URL url = new URL("www.something.somewhere");
in = url.getInputSrtream();

How about calling browser.setText() with the text that you got from the
URL's input stream?

browser.setText(inAsString);

You can't do that because there are URLs which are reachable only after
you got cookies, or passing through web forms.. The browser would make
this transparent for me.
