EXPERIMENTAL. The behaviour of this function, the
name of this function, and anything else documented about this
function may change in a future release of PHP without notice. Be
warned and use this function at your own risk. |
domxml_root() takes one argument, an object of class
"Dom document", and returns the root element node. There are actually
other possible nodes like comments which are currently disregarded.
The following example returns just the element with name CHAPTER and
prints it. The other root node -- the comment -- is not returned.
Example 1. Retrieving root element <?php
$xmlstr = "<?xml version='1.0' standalone='yes'?>
<!DOCTYPE chapter SYSTEM '/share/sgml/Norman_Walsh/db3xml10/db3xml10.dtd'
[ <!ENTITY sp \"spanish\">
