I want similar RSS FEED parser

somebody can help me?

You are limited to what kind of programming you can use on the blogspot.com service and need to start using a proper web hosting account. Take a look at X10hosting.com or 000Webhost.com, they provide everything you need to get started for free.

Suggest you use a piece of software called WordPress, both of the above hosts support it and it is free. Easy to set up, just one click to install. Then add the plugin packages to create a blog and special features that will take any RSS feeds you find and post them directly into your blog as your content. Wordpress.com has a forum that can help you choose the exact plugins you need.

Scanning Google automatically using a web server for lists of RSS feeds is difficult and you will need to learn some server-side programing language like PHP and understand how to use SQL databases. Google has a developers API that will allow you to run custom searches but you have to register with them to get a digital key to use it. There are ways of scraping the search results from Google without a key using a fake (headless) browser using a web server but the process is much more complicated.

Google can also get angry if they catch you scraping results directly and will bury the offending website so far down the search ranking even link spammers will not find it. They may also close your Adsense account if you have one and keep your money.

However...
If you have full access to a PC with an Internet connection there is a desktop software package called dJuggler that can mimic a web browser and be used compile lists of RSS feeds. It uses very simple plain instructions like "fetch page" and "copy content from" , comes with lots of working examples. There was a free but limited function version for personal use if you can find a copy otherwise you have to get the full 30 day trial version and work fast.

I want simple tools ))
