Php和Xpath - 如何从节点内部获取文本

How how can I get a text from inside a node using xpath?

如何使用xpath从节点内部获取文本？

For now I'm doing it like this:

现在我这样做：

$temp= $content->xpath('qwe/qwe');
$temp = each($temp[0]);
return $temp['value'];

But as you can see it's far from good solution :(

但正如你可以看到它远没有很好的解决方案:(

In c# it is as easy as

在c＃中它很简单

public string readXmlVar(string xpath)
{
    XmlNode xmlNode = xml.SelectSingleNode(xpath);
    return xmlNode.InnerText;
}

4 个解决方案

#1

For SimleXmlElement just cast it as a string: return (string) $temp;. For DomDocument use return $temp->nodeValue.

对于SimleXmlElement，只需将其转换为字符串：return（string）$ temp;。对于DomDocument，请使用return $ temp-> nodeValue。

Try:

尝试：

$dom = new DOMDocument;
$dom->loadXML('<root>
    <p>some text<br />some more text</p>
</root>');

$xpath = new DOMXPath($dom);
foreach ($xpath->query('/root/p/text()') as $textNode) {
    echo $textNode->nodeValue;
}

$textNode will be a DOMText.

$ textNode将是一个DOMText。

(string) current($xml->xpath("//group[@ref='HS_TYP']"))

Hope that helps
