Getting node's text in PHP DOM
提问by bgcode
How could I extract the string "text" from this markup using the PHP DOM?
如何使用 PHP DOM 从此标记中提取字符串“text”？
<div><span>notthis</span>text</div>
$div->nodeValueincludes "notthis"
$div->nodeValue包括“notthis”

So long as you can affect the DOM, you could remove that span.
只要你能影响 DOM，你就可以删除那个span.
$span = $div->getElementsByTagName('span')->item(0);
$div->removeChild($span);
$nodeValue = $div->nodeValue;
Alternatively, just access the text node of $div.
或者，只需访问$div.
foreach($div->childNodes as $node) {
if ($node->nodeType != XML_TEXT_NODE) {
continue;
}
$nodeValue = $node;
}
If you end up with more text nodes and only want the first, you can breakafter the first assignment of $nodeValue.
如果你最终得到更多的文本节点并且只想要第一个，你可以break在第一次分配$nodeValue.

You can access DOMTextnode directly using XPath:
您可以DOMText使用 XPath 直接访问节点：
$xpath = new DOMXPath($dom_document);
$node = $xpath->query('//div/text()')->item(0);
echo $node->textContent; // text
