從表單元素提取數據

Question

如何從<strong id="reference">123</strong>獲得123？

像下面這樣的東西。

/** 
* @Then /^I check reference in database$/ 
* @throws \Exception 
*/ 
public function checkReferenceInDb() 
{ 
    $session = $this->getSession(); 
    $page = $session->getPage(); 

    $element = $page->find('css', //I think I should do something here to process the page content); 

    if (null === $element) { 
     throw new \Exception(sprintf('Could not evaluate CSS element")); 
    } 

    $id = //123 should be assigned to this and I'll do the rest 
}

您可以使用快捷findById()：

$element = $page->findById('reference'); 

然後，使用​​從一個元素獲取文本：

$id = $element->getText();
