Reading a simple xml using php

Question

<key><name>testing name</name><result>success</result></key>

My PHP code:

$doc = new DOMDocument();
$doc->load( 'key.xml' );
$result = $doc->getElementsByTagName( "result" );
echo $result->item(0)->nodeValue;

I just need to extract the text value of "result", but it doesn't output that to me. Could you help me please?

Answer 1

i think you are using a regular variable as an object here. instead of

echo $result->item(0)->nodeValue;

why not use

echo $doc->item(0)->nodeValue;

since $doc is the instantiated object?
