title: Parsing html table from different domain
body: <p>i'm making an iOS app for showing schedule for my college. 
  I'm kinda new in javascript, i thought it's simple until now. I know this task may be simple and trivial, but listen:
  My application generates link with parameters and then creates a dynamic page with an iframe and opens link within it (src of an iframe sets to generated link), link leads to a page on a different domain, it has a HTML table with needed data in it's cells, each cell has it's own attribute, so i thought i could simply find each needed cell by it using DOM, but accessing iframe's DOM doesn't work. I can change absolutely nothing on server side - even college technicians do not know how it works and of course they'll not touch anything until it breakes. 
  So the question is: how can i get the text from the cells of that table by knowing their attributes and store it as a variable in javascript?</p>
  
  <p>Almost forgot, example of a page itself:
