将xml加载到php文件时，'xmlParseEntityRef：没有名称'警告

Question

I am reading an xml in php using simplexml_load_file. However while trying to load the xml it displays a list of warnings

Warning: simplexml_load_file() [function.simplexml-load-file]: <project orderno="6" campaign_name="International Relief & Development" project in /home/bluecard1/public_html/test.php on line 3    
Warning: simplexml_load_file() [function.simplexml-load-file]: ^ in /home/bluecard1/public_html/test.php on line 3

How do I rectify to remove these warnings?

(XML is generated from url http://..../index.php/site/projects & loaded into a variable in the test.php. I dont have write priveleges to index.php)

Answer 1

The XML is most probably invalid.

The problem could be the "&"

$text=preg_replace('/&(?!#?[a-z0-9]+;)/', '&', $text);

will get rid of the "&" and replace it with it's HTML code version...give it a try.
