How to move text from one page into the form of another page

[mega0079]

I have a page with information on it, let's say \[code\]<p>username=test</p><p>password=test2</p>\[/code\]i need to search through this page, find the value for username and the value for password, store them, probably in a variable. and carry them over onto a form on another page. like so:\[code\]Username: <input type="text" name="Username"><br />Password: <input type="text" name="Password">\[/code\]This second page i would very much like to not be on the same server. so using php POST is a tad out of the question, and i dont think you can carry variables between pages with javascript. Anyone have any ideas?note:also, i have no access to the code on the other server, (the form) however i understand that js can be ran out of the url bar, so perhaps i could use this to fill in the textboxes.
