How can the <title> element be deleted inside this XML string?

$input=
'<items>dfd jdh flkdjf 
<title>My Test Title
</title>....
<store>my store 1</store>
</items>.....';

$output=
    '<items>dfd jdh flkdjf 
        ....
    <store>my store 1</store>
    </items>.....';

Thanks

Simplexml 

$str = '<items>1<title>lalala</title><others>...</others></items>';
$xml = simplexml_load_string($str);
unset($xml->children()->title);
$output = str_replace("<?xml version=\"1.0\"?>\n", '', $xml->asXml());

If you are working with unknown input data, or with production code, you should use an XML parser.

If you're working in test environment and the input data is known:

$output = preg_replace('%<title>[^<]*</title>%', '', $input);

If you need to allow for attributes on the tag, I suggest using a real XML parser, for maximum reliability and minimum chance of error.
