Remember, Dom-Nodes mustn't start with a number:

allowed:
<t12345t4>Value</t12345t4>

Not allowed:
<12345t4>VALUE</12345t4>

Note that this function is buggy. You have to manually escape the $value argument with htmlspecialchars.

If you like to view an element simply do:

<?php
echo htmlentities($element->C14N());
?>


Undocumented but found ;)
