How to fetch html string of XPath results?

Considering this code:

<div class="a">foo</div&g开发者_如何学运维t;
<div class="a"><div id="1">bar</div></div>

If I want to fetch all the values of divs with class a, I'll do the following query:

$q = $xpath->query('//div[@class="a"]');

However, I'll get this result:

foo
bar

But I want to get the actual value including the children tags. So it'll look like that:

foo
<div id="1">bar</div>

How can I accomplish that with XPath and DOMDocument only?

Solved by the function provided here.

PHP DOM has an undocumented '.nodeValue' attribute which acts exactly like .innerHTML in a browser. Once you've used XPath to get the node you want, just do $node->nodeValue to get the innerhtml.

You can try to use

$xml = '<?xml version=\'1.0\' encoding=\'UTF-8\' ?>
    <root>
    <div class="a">foo</div>
    <div class="a"><div id="1">bar</div></div>
    </root>';

$xml = simplexml_load_string($xml);            
var_dump($xml->xpath('//div[@class="a"]'));

But in this case you will have to iterate objects.

Output:

array(2) { [0]=> object(SimpleXMLElement)#2 (2) { ["@attributes"]=> array(1) { ["class"]=> string(1) "a" } [0]=> string(3) "foo" } [1]=> object(SimpleXMLElement)#3 (2) { ["@attributes"]=> array(1) { ["class"]=> string(1) "a" } ["div"]=> string(3) "bar" } }

Try something like:

$doc = new DOMDocument;
$doc->loadHTML('<div>Your HTML here.</div>');
$xpath = new DOMXpath($doc);
$node = $xpath->query('//div[@class="a"]')->item(0);
$html = $node->ownerDocument->saveHTML($node); // Get HTML of DOMElement.
