What is this feature about (expected vs actual behaviour)?

When find for > span for example, throw a error Expected selector, but " at 0> found.

In the code above, first echo show real 29.30 nodes fine, but second one need to return just 29.30

How can I reproduce it?

$find = (new \voku\helper\HtmlDomParser())->loadHtml(<<<EOD
	<html>
		<body>
			<div class="card-action-item"></div>
			<div class="card-action-item">
				real <span>29.30</span> <span> nodes</span>
			</div>
		</body>
	</html>
EOD);

$find = $find->find(".card-action-item:nth-child(2)", 0);
$all = $find->text;
echo $all . "\n";

$find = $find->find("> span");
$just_value = $find->text;
echo $just_value . "\n";

Any additional information?

I have tested on another languages, and this may be a valid selector. am I doing something wrong?

As we can use xpath to create a selector too, enable axes can help (#103)

with this change, we can use something like this

$find = (new \voku\helper\HtmlDomParser())->loadHtml(<<<EOD
	<html>
		<body>
			<div class="card-action-item"></div>
			<div class="card-action-item">
				real <span>29.30</span> <span> nodes</span>
			</div>
		</body>
	</html>
EOD);

$find = $find->find(".card-action-item:nth-child(2)", 0);
$all = $find->text;
echo $all . "\n";  // print real 29.30 nodes

$find = $find->find("child::span");
$just_value = $find->text;
echo $just_value . "\n"; // print 29.30

if @voku accept the idea, i can implement another ones https://www.w3schools.com/xml/xpath_axes.asp
