按类分类的XPath选择器

Question

如何选择Stage One div内的文本。 它有一个独特的名称“field-name-field-stage-one”。 我想回应一下总结。

链接到网站： http ： //fosterinnovationculture.com/drupalc/？q = node / 17

这是我到目前为止：

$doc = new DomDocument;
$some_link = 'http://fosterinnovationculture.com/drupalc/?q=node/17';
$tagName = 'div';
$attrName = 'class';
$attrValue = 'field-name-field-stage-one';

$doc->validateOnParse = true;
$doc->loadHtml(file_get_contents($some_link));

$xpath = new DOMXpath($doc);
$elements = $xpath->query("/html/body//div[contains(@class,'$attrValue')]");

Answer 1

使用field-item类获取内部元素并提取nodeValue值：

$elements = $xpath->query("/html/body//div[contains(@class,'$attrValue')]/div[contains(@class, 'field-item')]");
print_r($elements[0]->nodeValue);

The survey results show that your organization is ‘interested’ in design-led innovation, which is stage 1 in our framework.

‘Interested’ means that some people in the organization are noticing design contributions and the methods designers use. Some individuals are experiencing success in a few projects.  The use of design methods is ad hoc, unintentional and happening at a grass roots level. Design continues to be perceived as an added cost to the development process. As a result, there is little executive support or buy-in.
