Use:
使用：
//iframe//span
This selects every spanelement that is a descendent of any iframeelement in the XML document.
这将选择作为 XML 文档span中任何iframe元素的后代的每个元素。

Elements in iframe are in fact in another page. so you should first find address of that page which is value of src value of iframe and load it and then access the element in that page.
iframe 中的元素实际上在另一个页面中。所以你应该首先找到那个页面的地址，它是 iframe 的 src 值的值并加载它，然后访问该页面中的元素。

You need to set the scope of the xpath to the iframe's contentDocument property:
您需要将 xpath 的范围设置为 iframe 的 contentDocument 属性：
var iframe = document.getElementsByTagName("iframe")[0];
var theFirstSpan = document.evaluate('//span', iframe.contentDocument,
null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue
回答by FailedDev
//span [ancestor::iframe]
This will select all span elements which at some point have an ancestor iframe element.
这将选择在某些时候具有祖先 iframe 元素的所有 span 元素。

We can't access elements within an iframedirectly. We need to swith to iframe first.
我们不能iframe直接访问 an 中的元素。我们需要先切换到 iframe。
I am using PHP Facebook webdriver and this is perfectly working for me.
我正在使用 PHP Facebook webdriver，这对我来说非常有用。
$driver->get("http://www.example.com"); // containing an iframe
$iFrame = $driver->findElement(
WebDriverBy::xpath('//iframe[@name="iFrameName"]') //name or id or whatever by which we can access.
);
$driver->switchTo()->frame($iFrame);
Now, we can access that spanas,
现在，我们可以访问它span，
$spanButton = $driver->findElement(
WebDriverBy::xpath('//span')
);
I hope this may help somebody !
我希望这可以帮助某人！
