Search and Replace (<br> for <br />)

[nfr]

Hello -

How can I replace all instances of "<br>" with "<br />" in a block of text? The "<br>" seems to be crashing my XML feed because there is no "</br>".

Thanks and regards,

Neil.

I also need to perform the following on the text:

1.) replace all instances of "&nbsp " with " "
2.) remove all instances of "line start<P></P>line end"
3.) remove all instances of "line start<P>&nbsp;</P>line end"
4.) replace all instances of "line start<P></P><article>line end" with "<article>"

This is to clean up data. How can I do all of this in once hit?

Regards,

Neil.

Look at the functions [a href=\"http://www.php.net/str_replace\" target=\"_blank\"]str_replace()[/a] and [a href=\"http://www.php.net/strip_tags\" target=\"_blank\"]strip_tags()[/a].

How can I search on a line start and a line end?

I've got the following to replace the "<BR>" tags with "<BR />" but how can I remove a line such as:

line start<P>&nbsp;</P>line end

Regards,

Neil.

For that you need to use the regular expression functions. I really can't help you there, since I still can't understand them myself.
