我有以下html:
<div class="data">
<p class="info">output</p>
<p class="info">output2</p>
我正在尝试使用以下
获取文本“output”$xpath = new DOMXPath($dom);
foreach ($xpath->evaluate("//div[@class='data']/p[1]") as $elt) {
$output=$elt->wholeText;
}
echo $output;
它不起作用。我收到2个错误:
Message: Undefined property: DOMElement::$wholeText
Message: Undefined variable: output
有人能指出我正确的方向吗?
提前致谢,

试试这个:
$xpath = new DOMXPath($dom);
$elements = $xpath->query("*/div[@class='data']");
if (!is_null($elements)) {
foreach ($elements as $element) {
$nodes = $element->childNodes;
foreach ($nodes as $node) {
echo $node->nodeValue. "\n";
}
}
}
