使用php跳过xml代码中的2个元素

Question

I have this XML data:

<root>
 <child>child1</child>
 <child>child2</child>
 <child>child3</child>
</root>

I can parse it with PHP:

$xml = simplexml_load_string($string);

I want to skip the first 2 children and get this result:

<root>
 <child>child3</child>
</root>

Thank you

You can query the element you're interested in with an Xpath query:

$xml  = new SimpleXMLElement($string);

$last = $xml->xpath("child[last()]")[0];
