Kundi la Vitambulisho vya XML vilivyojumuishwa ndani katika PHP

Sasa hebu tuchukulie kuwa kuna vitambulisho vingi, ambavyo kila kimoja kina vitambulisho ndani yake:

<root>
	<tag>
		<elem>maandishi1</elem>
	</tag>
	<tag>
		<elem>maandishi2</elem>
	</tag>
	<tag>
		<elem>maandishi3</elem>
	</tag>
</root>

Tutapitia vitambulisho vyetu kwa kutumia kitanzi na kutoa thamani za vitambulisho vilivyomo ndani:

<?php
	foreach ($xml->tag as $tag) {
		echo $tag->elem; // 'maandishi1', 'maandishi2', 'maandishi3'
	}
?>
