[Need help to limit number of Rss feed entries via PHP/XML]

Hello,

 

I have a real estate website, a rss feed and I use feedburner for email subscriptions etc.

 

Since last week, feedburner is not working anymore cause it says that my feed is larger than 512 KB.

 

Well, i would like to change the code of the feed in order to display only the last 200 items (now we have 300), but i tried many ways and didnt have any luck

 

Another solution would be setting a minimum date for publishing the items, for example to set the feed to publish items only if their publication date was after a particular month or day.

 

here is my code, can you help me to limit number of items, please?

 

Thanks in advance
