Yep, you can do it, but you fost must allow you to execute php, I guess you know that.
It's also possible to make the server to parse the .html files for php code too. Anyway, you just need a parser in php, which is very easy to find in google.
I'll give you here one class that does the reading, but I have changed it at some points, because it was part of bigger site. Keep in mind that, if it does something you don't know why
Code:
<?php
/*
+--------------------------------------------------------------------------------+
| RSSReader
+--------------------------------------------------------------------------------+
|
| Description
| -> Reads a given RSS feed
|
| Features
| -> You can customize the initial opening tag by setting
| the $main_id var
| -> You can also customize which tags RSSReader will
| recognize as sub tags by adding tags to the $sub_keys
|
| Usage:
| $rss = new RSSReader("http://http://rss.news.yahoo.com/rss/topstories");
| $rss->Read();
| // For complete feed array:
| print_r($this->feed['array']);
| // For just the items:
| print_r($this->feed['items']);
|
| OR
|
| $rss = new RSSReader();
| print_r($rss->Read("http://rss.news.yahoo.com/rss/topstories"));
