PHPDOMnodeValue不是'；行不通

我试图用DOM解析一个HTML表，它可以正常工作，但当某些单元格包含HTML时，它就不能正常工作

下面是示例HTML表

电子邮件为空，必须是：

<img src="generateImage.php?email=myemail@domain.com"/>

而不是

$cells->item(1)->textContent;

---

但这也不起作用。如何使其返回HTML值？

将id作为项目规格提供给您的表

 $dom = new DOMDocument();
        @$dom->loadHTML($html);
        $x = new DOMXPath($dom); 


    $table = $x->query("//*[@id='item_specification']/tr");
    $rows = $table;
    foreach ($rows as $row) {
     $atr_name = $row -> getElementsByTagName('td')->item(0)->nodeValue;
     $atr_val = $row -> getElementsByTagName('td')->item(1)->nodeValue;
     }

echo " {$atr_name} - {$atr_val} <br \>";

$dom=newdomdocument（）；
@$dom->loadHTML（$html）；
$x=新的DOMXPath（$dom）；
$table=$x->query（“//*[@id='item_specification']]/tr”）；
$rows=$table；
foreach（$行作为$行）{
$atr_name=$row->getElementsByTagName（'td'）->项（0）->节点值；
$atr_val=$row->getElementsByTagName（'td'）->项（1）->节点值；
}
回声“{$atr_name}-{$atr_val}”；

工作正常。

正如我已经提到的，

不是文本。它是另一个html实体。所以试试这个：

if(strpos($cells->item(0)->textContent, "Razon") !== false) {
    $_razonSocial = $cells->item(1)->textContent;
} else if(strpos($cells->item(0)->textContent, "Email") !== false) {
    $count = 0;
    // here we get all child nodes of td.
    // space before img-tag is also a child node, but it has type DOMText
    // so we skip it.
    foreach ($cells->item(1)->childNodes as $child) {
        if (++$count == 2)
            $_email = $child->getAttribute('src');
    }
    // now in $_email you have full src value and can somehow extract email
}

定义“工作不正常”。有错误吗？没有错误，它不会返回任何内容。只是空的。这个变量不是空的吗$_你确定吗？知道吗，希万@Aveendra其为空。

不是文本。它是另一个html实体<代码>$cells->item（1）->item（0）->attr（'src'）也许

$cells->item(1)->nodeValue;

$cells->item(1)->textContent;

 $dom = new DOMDocument();
        @$dom->loadHTML($html);
        $x = new DOMXPath($dom); 


    $table = $x->query("//*[@id='item_specification']/tr");
    $rows = $table;
    foreach ($rows as $row) {
     $atr_name = $row -> getElementsByTagName('td')->item(0)->nodeValue;
     $atr_val = $row -> getElementsByTagName('td')->item(1)->nodeValue;
     }

echo " {$atr_name} - {$atr_val} <br \>";

if(strpos($cells->item(0)->textContent, "Razon") !== false) {
    $_razonSocial = $cells->item(1)->textContent;
} else if(strpos($cells->item(0)->textContent, "Email") !== false) {
    $count = 0;
    // here we get all child nodes of td.
    // space before img-tag is also a child node, but it has type DOMText
    // so we skip it.
    foreach ($cells->item(1)->childNodes as $child) {
        if (++$count == 2)
            $_email = $child->getAttribute('src');
    }
    // now in $_email you have full src value and can somehow extract email
