Reading content in XML on server

[Twey]

- 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.

-The XML file can have any extension.
-The loop is something like:

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

What will do actually this code?

Use the directory functions to look for the appropriate filename structure in a specified directory.

Can you tell specific function to use directory function? Need help...

What will do actually this code?

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.
