PHP Xpath 帮助，无法解析 HTML

Question

我正在尝试从下面的 TR 代码中获取 2 个值

1) xyz.com 2) 这太好了，我会给 100 美元

以下是我尝试 Xpath/Parse 的 HTML 代码，但无法获得所需的结果。

<tr class="something-is-here">
<td>xyz.com</td>
<td class="text-right">
<span>this is great i will give 100 bucks
</span>
</td>
</tr>

尝试了以下方法，但似乎不起作用。

        $html = new simple_html_dom();
        $html->load($content);
    foreach($html->find('tr') as $myLink) {
        $href = $myLink->span;
if (!is_null($myLink)) {
    foreach ($myLink as $element) {
        $nodes = $element->childNodes;
        foreach ($nodes as $node) {
            echo $node->nodeValue. "\n";
        }
    }
}

非常感谢任何帮助。 谢谢。

一种解决方案可能是：

<?php
$xml = <<<'XML'
<tr class="something-is-here">
<td>xyz.com</td>
<td class="text-right">
<span>this is great i will give 100 bucks</span>
</td>
</tr>
XML;
$document = new DOMDocument();
$document->loadXML($xml);
$xpath = new DOMXpath($document);
$elements=$xpath->query('//tr//*[text()[normalize-space()]]');
foreach($elements as $element)
echo $element->nodeValue. "\n";
?>

输出：

xyz.com
this is great i will give 100 bucks

编辑：假设你有 HTML：

$dom = new DomDocument();
$data='<tr class="something-is-here">
<td>xyz.com</td>
<td class="text-right">
<span>this is great i will give 100 bucks
</span>
</td>
</tr>';
$dom->loadHTML($data);
$xpath = new DOMXpath($dom);
$elements=$xpath->query('//tr//*[text()[normalize-space()]]');
foreach($elements as $element)
echo $element->nodeValue. "\n";
