Can i use php loops in xml file to list out a list of number incremented file names such as file 1.jpg file2.jpg file3.jpg etc to save me having to manually typing it out. If so, how do I do this and what doctype etc would the xml file need to have to make it display the loop?

What is your desired output? What have you tried so far?user21926– user219262012-09-25 12:55:13 +00:00Commented Sep 25, 2012 at 12:55

Your question is a little vague, I can't work out if you're trying to read an XML file or write to it.
Assuming you want to read an XML file, and assuming your XML looks a little like this:
<?xml version="1.0" encoding="utf-8" ?>
<rootnode>
<images>
<image>file_1.jpg</image>
<image>file_2.jpg</image>
<image>file_3.jpg</image>
</images>
</rootnode>
you could use SimpleXML to either load the XML file or to load the XML as a string and then return an object to loop through. http://php.net/manual/en/ref.simplexml.php
Your PHP might look something like this:
if (file_exists('test.xml')) {
$xml = simplexml_load_file('test.xml');
foreach($xml->images AS $image) {
echo $image;
}
} else {
exit('Failed to open test.xml.');
}

Just want to know if there is a simple way of producing a list of file names in an xml file such as file1.jpg file2.jpg file3.jpg using say a php loop instead of me having to list out from file1.jpg upto file80.jpg thanks
What I would do is point to a .php file that outputs XML. All you need to do that is send a header("Content-Type: text/xml"); and make sure you add the at the top of your output.
Here's an example:
<?php
header("Content-Type: text/xml");
print "<?xml version=\"1.0\"?>";
print "<rootNode>";
for(your loop stuff here) {
print "<node>" . $yourDataHere . "</node>";
}
print "</rootNode>";
?>
