I would like to automaclly get posts in a thread manually. Here's my design: -Bot goes to topic, looking for posts -He would search for a <a name="POSTIDHERE">, idenfity it and start the logging loop -Firstly he searches for a field <span id="author"> and logs the content inside it -Then he searches for a field <span id="content"> and logs the content of it -Finally flush it into database (or do it when a step is completed) -When all posts on the page are dealt, move to the next page I don't have a problem with looping ATM, the place I am confused is the second step and the logging steps. How would I do them? In JavaScript there is something called getElementsById. I cannot find the same function in PHP. Thanks!
