PHP - Getting an XML file that is echoed in another PHP file, then saving the echoed XML output to the server -

i have php file - called xml_generate.php - creates dom object , echoes @ end.

lets looks this:

header("content-type: text/xml");   $dom = new domdocument('1.0'); $node = $dom->createelement('foo'); $root = $dom->appendchild($node);  $node = $dom->createelement('bar'); $new_node = $root->appendchild($node);  echo $dom->savexml(); 

i'm accessing file jquery , displaying content on client-side. actual xml_generate.php creates dom dynamically database.

however, want have php file create backup of xml generated generate_xml.php , save server.

so, need somehow access xml document (the 1 dynamically created in xml_generate.php).

i've tried a few different functions xml xml_generate.php, instance:

$xml = http_get('xml_generate.php');,

$xml = file_get_contents('xml_generate.php');

as including first file (include('xml_generate.php'), trying access $dom variable in file).

but can't seem right. ideas on best approach this?

you use output buffering, buffer data sent output stream, , retrieve after including script:

ob_start(); include "xml_generate.php"; $xml = ob_get_contents(); ob_end_clean(); 

make sure catch errors @"xml_generate.php" though, or these buffered , you'll end invalid xml backup.
