Hello all,

I am working on trying to receive an RSS feed and insert it into a scrolling box for students to read their local news, I get everything and it works fine, except that the RSS feed puts some kind of weird server side line breaks into it. I was curious if anyone knew how to remove any unconventional line breaks from a feed that is ASP driven (i.e. \r, \n, etc). When it comes in, there are mysterious carraige returns all over the place that I can't seem to remove, and my js feed rotator needs everything to be in one line, so page breaks breaks the javascript. I am currently running the following commands on it and these do not fix this particular page break:

php addslashes(trim(strip_tags($this->title)))

Any thoughts or ideas would be wonderful. I googled asp page breaks and didn't see anything obvious. As always, thank you. I have wasted like 50 hours of my life trying to fix these little errors.

str_replace("\r\n","",$this->title)

Unfortunately that doesn't work. Trim already yanks out \r & \n. I have tried everything conventional. I've gone as far as trying things like
str_replace("chr(13)","",$this->title). The following is an idea of basically what it is doing (i put in the double spaces everywhere it puts a fresh line)

        fcontent[0]='<b><a alt="http://www.ourwebsite.com/podium/default.aspx?t=204&id=9ohiVgu8jcc%3d">Happy Birthday!</a></b><br />Dec 2  firstname lastname, firstname lastname

Dec 3 firstname lastname

Dec 7  firstname lastname, firstname lastname, firstname lastname,  firstname lastname'

        closetag='</div>';

It is supposed to look like:

        fcontent[0]='<b><a alt="http://www.ourwebsite.org/podium/default.aspx?t=204&id=9ohiVgu8jcc%3d">Happy Birthday!</a></b><br />Dec 2 firstname lastname, firstname lastname Dec 3 firstname lastname Dec 7 firstname lastname, firstname lastname, firstname lastname, firstname lastname'
        closetag='</div>';

The person running this rss feed is putting <ul>'s & <li>'s around each date. Which I remove with strip_tags(), but trim doesn't get rid of the carraige returns. It does remove them in all other feeds.

I can remove the carraige returns from a normal RSS feed.

I think you need to re-read what the trim function actually does.
http://php.net/manual/en/function.trim.php
It doesn't strip all CR's and LF's, only those at the beginning and end of the supplied string.

Oh, thank you, I hadn't noticed that trim() is only for the beginning & end of things. That in itself is very helpful to know.

str_replace() did not originally fix it... I did give str_replace("\r\n","",$this->title) another try, to no avail. until I realized I've wasted a huge amount of time on the title, rather than the subject. I even posted the problem referring to $this->title, rather than $this->description. Thank you again.. I suppose after staring at one thing for 5 straight days, I got careless..

Thank you and sorry for such a dumb fix. My problems always seem to get solved when I post here.

Resolution:

PHP Code:

class rss {
   //array containing unneccessary page breaks
   var $order = array("\r\n", "\n", "\r", "chr(13)",  "\t", "\0", "\x0B");

   //For title, print the following after stripping everything that is not plain text.
   printf('<b><a alt="%s">%s</a></b><br />', trim($this->link), addslashes(strip_tags(str_replace($this->order, "", $this->title))));

   //For content, print the following after stripping everything that is not plain text.
   printf("%s", addslashes(strip_tags(str_replace($this->order, "", $this->description))));
}
