PHP DOMDocument和DOMXpath

PHP DOMDocument And DOMXpath

我正在尝试使用DOMDocument / DOMXpath在HTML块中找到最后一个段落标签，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返回一个空的DOMText Object ( ) ...关于如何使用DOMDocument / DOMXPath在HTML块中查找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']);

使用此代替：

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