问题描述
我有以下代码来检索HTML文档中的所有超链接
I have the following code to retrieve all hyper links in an HTML document
，我的问题是如何检索每个锚标签内的文本节点
and my question is how to retrieve the text nodes inside every anchor tag
（即使文本节点是子节点的子节点，如果该节点的节点具有一个文本节点）？
(even if the text node is a child of a child like if the anchor node has a span node which has a text node)?
<?PHP
$content = "
<html>
<head>
<title>bar , this is an example</title>
</head>
<body>
<a href='aaa'><span>bbb</span></a>
</body>
</html>
";
$dom = new DOMDocument();
@$dom->loadHTML($content);
$xpath = new DOMXPath($dom);
$row = $xpath->evaluate("/html/body//a");
for ($i = 0; $i < $row->length; $i++) {
$anchor = $row->item($i);
$href = $anchor->getAttribute('href');
// I want the grab the text value which is inside the anchor
$text = //should have the value "bbb"
}
?>
