Fonctions SimpleXML
simpleXML have only read/write methods. Then how to remove attributes in node?
There is a simpe way to remove attribute without DOM extension. Use unset();
Example:
if "samlpe.xml" contains
<?xml version="1.0"?>
<books>
<book author="unknown">The Secret History of the Mongols</book>
<book author="Jack Weatherford">Genghis Khan and the Making of the Modern World</book>
<book author="David Morgan">The Mongols (The Peoples of Europe)</book>
<book author="Stephen Turnbull">Mongol Warrior 1200-1350</book>
<book author="Marco Polo">The Travels of Marco Polo</book>
<book author="J. J. Saunders">The History of Mongol Conquests</book>
</books>
<?php
// load xml file
$xml = simplexml_load_file("sample.xml");
// remove first book's attribute
unset($xml->book[0][author]);
// write xml file
$xml->asXML("sample.xml");
?>
Now "sample.xml" is:
<?xml version="1.0"?>
<books>
<book>The Secret History of the Mongols</book>
<book author="Jack Weatherford">Genghis Khan and the Making of the Modern World</book>
<book author="David Morgan">The Mongols (The Peoples of Europe)</book>
<book author="Stephen Turnbull">Mongol Warrior 1200-1350</book>
<book author="Marco Polo">The Travels of Marco Polo</book>
<book author="J. J. Saunders">The History of Mongol Conquests</book>
</books>
That's it.

Please note: currently this function does not return the object on which it is executed so function chaining is not possible.

It may be helpful to note that the addAttribute method checks the length of the fields to determine whether or not they are empty. In otherwords if you are trying to addElement("patent_holder", "") this will fail as the strlen is 0.
