Getting Only the first result of a DOM xPath query

Question

Let's say I have this code:

$dom = new DOMDocument();
@$dom->loadHTMLFile('sample.html');
$xp = new DOMXPath($dom);
$result = $xp->query("//input[@id='honey']");

How do I get the content of the attribute value of the first result only, since I'm only expecting one result (without using a foreach loop). I tried var_dump-ing the result but it can't. I also tried current($result)->getAttribute('value') but not luck.

Answer 1

You can access it via the following method:

$value = $result->item(0)->attributes()->getNamedItem("value")->nodeValue;

Answer 2

Just evaluate this XPath expression:

(//input[@id='honey'])[1]/@value

This selects the attribute value of the first input element in the XML document, the string value of whose id attribute is "honey".

If you want to get not the value attribute, but its string value, use:

string((//input[@id='honey'])[1]/@value)
