[SOLVED] RSS

Hello everyone,

I have a problem with printing a description of rss.
I use lastRSS 0.9.1. But I Think that doesn' matter.

The problem is that in de description html code is not decoded.

exemple of description :

Sla oa. Britney Spears op haar bakkes...<BR><A HREF="http://www.heavy.com/heavy2003/content/ ... tchslap<BR>

How can I print the description that a <br> makes a New line and the Link is clickable.

That is what I do :

Code: Select all

echo $item&#1111;'description'];

Thanks !

Are the < > things actually those characters, or are they the html entity equivalents?

I don't know, this is the code :
Rss_Print is the function I excecute (start with)
On line 251 the description is printed.

Code: Select all
