maybe take a look at the RSS in Siena? That one can be limited to a certain amount of characters, so maybe you can copy/extract it from there..

@Kingsley
I was not aware of that (not using Sienna yet except a few preparations for new sites), thx for the tip.

@Trustmaster
Excellent, thanks for that code. I have added it to the RSS, now I need to wait till those sites update to see what content they are now showing to be sure its working :)

@Kingsley

I don't really exprect everyone to be a PHP coder here, so nevermind.

You can check how it's doing immediately by browsing http://example.com/rss.php

Yes, I understood that and I did view my changes there. I was just interest to see what would happen on those sites.
And yes, everything works but to be honest I am not really happy with how my RSS feed is now looking. Its a bit messy, have a look at it here:
http://www.armaholic.com/rss.php

Due to limitting the number of characters the text in the RSS is cut of in a very ugly way. That was the intention indeed but right now I am trying to find some more ways to protect my content.
So I was thinking, instead of limitting the content I wanted to remove the images from the RSS so sites using my RSS wont look so nice with their pictureless articles.
I searched around on the net and saw many people prevent images to show in their RSS by adding some rules to their CSS but I guess since this is a pure PHP RSS that wont work.
But I found a function which I am now trying to use but it is actually stopping any output from the RSS when I add it.
This is the function I found ( http://bavotasan.com/2011/a-better-way-to-remove-images-from-a-wordpress-post/ ), I changed it a bit hoping it would work in the genoa RSS:

// custom function to remove pics from the RSS
function remove_images( $text ) {
   $postOutput = preg_replace('/<img[^>]+./','', $text);
   return $postOutput;
}
add_filter( 'sed_parse', 'remove_images', 100 );

And its very possible I am doing something stupid here but yeah ........... PHP is not mine, I am just trying

Thanks for that code Trustmaster!
I added something extra to it to allow certain html codes just so the RSS output would not look idiotic or so non-apealing RSS readers would just end the RSS readers. This is the code I use now:

return mb_substr(strip_tags($text, '<strong><a><i><ul><ol><center><br><img>'), 0, 700)." ........... <br /><br /><span class=\"readmore\"><a href=\"".$pag_pageurl."\">".'Read the full article on Armaholic'."</a></span><hr style=\"size:5px;\">";
