Hello,
i am a newbie on php programming and try working on my last project in my school. My program is to compare 2 different xml file, it working well at first. but when i tried to add more xml file to compare, the page keeps telling "Fatal error: Call to a member function hasChildNodes() on a non-object" i dont know why :(
anyone has an idea why this message keeps appear? thank you.. your comment is much appreciated.
this is the error :
Fatal error: Call to a member function hasChildNodes() on a non-object in C:\xampp\htdocs\new_6jan.php on line 46
this is the code of new_6jan.php
