What is the question? XML files are strings of data.  PHP string variables can have variable substitution.

Ray PaseurCommented:
OK, from an array to XML is easy enough. Where would we get the information shown in the <lastmod> tag?  Once we have that, I can show you how to build this.

Nevermind, I just noticed that you had a comment about lastmod earlier.  Sorry.

// TEST: IS IT A VALID XML DOCUMENT?
$obj = SimpleXML_Load_String($xml);

// SHOW THE WORK PRODUCT
echo htmlentities($xml);

The test near line 40 will throw a message out if the XML is not valid.  HTH, ~Ray
