Reading content in XML on server

- Can you tell me if XML files can as extension HTML or allways XML? I'm new.

Any file can have any extension. Extensions are only a convention to make the contents of the file more easily guessable at a glance, and don't have any bearing on the actual content of the file.

PHP Code:

for ($i = 0; $i < $items->length; $i++) 
{
echo $items->item($i)->nodeValue . "\n";
}

Absolutely nothing, as the variable "items" isn't defined. It's an example of code that loops through all the elements inside a given element (or is that an array of elements? I don't know much about the PHP implementation of XMLDOM) and echoes the values of all tags inside it.

Thank you for the start,:)
