PHP DomXpath HTML表值（按文本）

Question

我有一个关于通过th值提取td值的小问题

这是一个表格示例：

<table>
<tr><th>Name:</th><td>Will</td></tr>
<tr><th>Size:</th><td>41</td></tr>
<tr><th>Clock:</th><td>GMT</td></tr>
</table>

我想通过值“名称：”获得“意愿”值

在jQuery我做：

$('th:contains(Name:)').next().text(); //Will Show Will
$('th:contains(Size:)').next().text(); //Will show 41

但是想通过PHP DOMDocument做到这一点

$dom = new DOMDocument();
$html = $dom->loadHTMLFile("src/load.html");
$dom->preserveWhiteSpace = false; 
$selector = new DOMXPath($dom);

$name=$selector->query('//th[contains(.,"Name:")]')->?
$size=$selector->query('//th[contains(.,"Size:")]')->?

谢谢
