php - PHP DOMDocument 和 DOMXpath

Question

我正在尝试使用 DOMDocument/DOMXpath 在 HTML 块中找到最后一个段落标记，但似乎无法弄清楚。

# Create DOMDocument Object
        $dom = new DOMDocument;
        # Load HTML into DomDocument Object
        $dom->loadHTML($data['component2']);

        # Creat DOMXPath Object and load DOMDocument Object into XPath for magical goodness
        $xpath = new DOMXPath($dom);

        # Loop through each comment node
        foreach($xpath->query('//p') as $node) {
            // krumo($node->parentNode);
            print_r($node->parentNode->lastChild);
        }
        exit();

print_r返回一个空DOMText Object ( )......关于如何使用 DOMDocument/DOMXPath 在 HTML 块中找到最后一段的任何想法？

工作代码：

# Create DOMDocument Object
        $dom = new DOMDocument;
        $dom->preserveWhiteSpace = false;
        # Load HTML into DomDocument Object
        $dom->loadHTML($data['component2']);

        # Creat DOMXPath Object and load DOMDocument Object into XPath for magical goodness
        $xpath = new DOMXPath($dom);
        $q = $xpath->query('//div[@class="t_content"]/p[last()]');

        $data['component2'] = str_replace(utf8_decode($q->item(0)->nodeValue), "", $data['component2']);

Answer 1

改用这个：

 print_r($node->parentNode->lastChild->nodeValue);
