如何在php中搜索和删除字符串

Question

I am attempting to use an RSS feed from Twitter (the ones that will be gone a year from now) with Feedburner but a line of code in the xml is causing a parsing error in feedburner. I think it's

xmlns:twitter="http://api.twitter.com"

I am looking for a way to give this information to feedburner in a way that it likes: namely php including the contents of the RSS xml page in an xml on my own site (with the offending string removed). Including the xml contents is a piece of cake - all I need is a piece of code to say iff string fragment == xmlns:twitter="http://api.twitter.com" then string frament = "".

Anybody any idea of the syntax for this?

You can try with str_replace:

str_replace('xmlns:twitter="http://api.twitter.com"', '', $string);

Also, you can try to urlencode http://api.twitter.com.
