问题
I'm trying to come up with one or more rewrite rules that will take either a friendly url or a url containing the full query string.
The plan is to create a text-only page by reading in the URL using PHP's loadHTML.
For example:
Input
1. http://www.example.com/disclaimer (http://www.example.com/text/disclaimer on text-only version)
2. http://www.example.com/info/aboutus (http://www.example.com/text/info/aboutus on text-only version)
3. http://www.example.com/news?id=123 (http://www.example.com/text/news?id=123 on text-only version)
Output
1. http://www.example.com/includes/textonly.php?page=disclaimer
2. http://www.example.com/includes/textonly.php?page=info/aboutus
3. http://www.example.com/includes/textonly.php?news?id=123
So on the textonly.php I would use $_GET['page']); for example 1) and 2), and use $_SERVER['QUERY_STRING']; for example 3).
For example 1) and 2), I came up with:
RewriteRule ^text/(.*) includes/textonly.php?page=$1
And for example 3), I came up with:
RewriteRule ^text/(.[?]) /includes/textonly.php [QSA]
They work independantly but not together. Can anyone help?

With guidance from Tom and Michael, this is what I've come up with:
in Htaccess send everything to PHP in the querystring:
RewriteRule ^text/(.*) /includes/textonly.php [QSA,L]
Then in PHP:
$page = 'http://'.$_SERVER['HTTP_HOST'].'/'.str_replace('/text/','',$_SERVER['REQUEST_URI']);
Seems to work for both friendly urls (2 levels deep tested so far) and querystrings. Hopefully its okay, so I'll go with this as a solution :)

I suggest handing control over to PHP - I wrote an article on this a while ago - http://tomsbigbox.com/elegant-url-rewriting/ - it details how to send the query string to a PHP file that then decides what to do - so if the page exists for example it will load it, otherwise do something else.
I've found that to be the best solution to URL rewriting.

I'd change your rewrite rule to look like this:
RewriteRule ^([^/\.]+)/?([^/\.]+)?/?$ /includes/textonly.php?page=$1&id=$2 [L,NC]
Then slightly modify your Input URLs to look like this:
1. http://www.example.com/disclaimer
2. http://www.example.com/info/aboutus
3. http://www.example.com/news/123
And they would point to these URLs:
1. http://www.example.com/includes/textonly.php?page=disclaimer&id=
2. http://www.example.com/includes/textonly.php?page=info&id=aboutus
3. http://www.example.com/includes/textonly.php?page=news&id=123
The regex above will match anything between the /, not including a / or a .. The second half is optional, so in that rule, you could only go two directories deep.
Controlling all three URLs in the same way will make your logic a little cleaner on the textonly.php page as you do not need to write special logic for the first two URLs compared to the last.
