You can use codemirror editor, to edit your file and you need to implement saving in php on server side. You can post the content using jquery

$.post('your_script.php', {file: myCodeMirror.getValue()}, function() {
   // your file was save
});

and in php

if (isset($_POST['file'])) {
  $f = fopen('your.xml', 'w')
  fwrite($f, $_POST['file']);
  fclose($f);
}
