How to parse XML with SimpleXML

[WPPJames]

I have pass a URL statement to a server:

http://query.directrdr.com/ptrack?pid=458&v_url=http%3A%2F%2Fwww.google.com&feed=1&said=321&ip=96.226.232.199&ua=Mozilla%2F4.0+%28compatible%3B+MSIE+7.0%3B+Windows+NT+5.1%3B+.NET+CLR+2.0.50727%3B+.NET+CLR+3.0.4506.2152%3B+.NET&keyword=

The server processes that and returns an XML file like so:

<?xml version="1.0" encoding="utf-8" ?> 
- <ads Type="Popup">
- <ad>
- <url>
- <![CDATA[ 
http://www.directrdr.com/v3.php?pid=458&cid=0&crid=0&t=0(0)&cc=840&said=321&params=192517761ab0192da0b22aa71dd64470e1c7545a-3U.ssU.sFs.w33%09f.ffsfff%09jotLsoqaIEvERY%09ws4kU4UwFw%092vvR%3A%2F%2FwwFsFsWai.ERvzv.EtQ%2FERY.1NR%3FR%3DwwFsFs%26RjavLIamqL%3Df.ffw%26atLmqL%3Df.ffw%26Wai%3D2vvR%25Fh%25s6%25s6nnn.zttziI.EtQ%26qR%3D3U.ssU.sFs.w33%26jqo%3DkSu%26NWAqo%3DkSu-Fsw%26NIiIEvIodI0ntao%3DzttziI%20EtQ%26NIiIEvIoVqNvqLzgo%3D4S3fF4w&pc=19-7590371&vurl=http%3A%2F%2Fwww.google.com&mm=20
  ]]> 
  </url>
  <cpvrate>0.002</cpvrate> 
  <creativeid>0384258679</creativeid> 
  <campaignid>19-7590371</campaignid> 
  <max-imp-per-user>1</max-imp-per-user> 
  <frequency-period>24</frequency-period> 
  </ad>
  </ads>

I attempt to capture portions of the XML data by using SimpleXML:

simplexml_load_file($request_url,'SimpleXMLElement', LIBXML_NOCDATA);
$adtype = (string) $xml['Type'];
$outurl = (string) $xml->ad->url;

$outurl is now set to:

http://www.directrdr.com/v3.php?pid=458&cid=0&crid=0&t=0(0)&cc=840&said=321¶ms=f187e570d6b79abd9b963fbde6d108c7c8174f5d-3U.ssU.sFs.w33%09f.ffsfff%09jotLsoqaIEvERY%09ws4kU4uwu3%092vvR%3A%2F%2FwwFsFsWai.ERvzv.EtQ%2FERY.1NR%3FR%3DwwFsFs%26RjavLIamqL%3Df.ffw%26atLmqL%3Df.ffw%26Wai%3D2vvR%25Fh%25s6%25s6nnn.zttziI.EtQ%26qR%3D3U.ssU.sFs.w33%26jqo%3DkSu%26NWAqo%3DkSu-Fsw%26NIiIEvIodI0ntao%3DzttziI%20EtQ%26NIiIEvIoVqNvqLzgo%3D4S3fF4w&pc=19-7590371&vurl=http%3A%2F%2Fwww.google.com&mm=22

As you can see, there is a carriage return character within the $outurl variable (=321¶ms=), which shouldn't be there. Any ideas why that is happening? Also, are parentheses allowed in an url, such as "(0)" above.

Never mind. My developer figured it out.

&para = ¶
in ascii

&params is getting converted into ¶ms

Now off to find a workaround.
