深入研究 DOMElement

我已经使用 Zend_Dom_Query 提取了一些元素，现在我想循环遍历它们并执行更多操作。每个看起来像这样，那么如何打印标题Title 1和第二个td的idid=categ-113？

<tr class="sometr">
  <th><a class="title">Title1</a></th>
  <td class="category" id="categ-113"></td>
  <td class="somename">Title 1 name</td>
</tr>

I've used Zend_Dom_Query to extract some <tr> elements and I want to now loop through them and do some more. Each <tr> looks like this, so how can I print the title Title 1 and the id of the second td id=categ-113?

<tr class="sometr">
  <th><a class="title">Title1</a></th>
  <td class="category" id="categ-113"></td>
  <td class="somename">Title 1 name</td>
</tr>

你应该只是玩弄结果。我从来没有使用过它，但这就是我所取得的进展（我自己对 Zend 还很陌生）：

$dom = new ZEnd_Dom_Query($html);
$res = $dom->query('.sometr');

foreach($res as $dom) {
  $a = $obj->getElementsByTagName('a');
  echo $a->item(0)->textContent; // the title
}

有了这个，我想你就可以开始了。有关结果的更多信息和要使用的函数，请查找 DOMElement ( http://php. net/manual/de/class.domelement.php ）。有了这些信息，您应该能够掌握所有这些信息。但我的问题是：
为什么这样做如此复杂，我真的没有看到这样做的用例。由于标题和其他所有内容都应该来自数据库？如果它是 XML，则有比依赖 Dom_Query 更好的解决方案。

无论如何，如果这对您有帮助，请接受和/或投票答案。

You should just play around with the results. I've never worked with it, but this is how far i got (and im kinda new to Zend myself):

$dom = new ZEnd_Dom_Query($html);
$res = $dom->query('.sometr');

foreach($res as $dom) {
  $a = $obj->getElementsByTagName('a');
  echo $a->item(0)->textContent; // the title
}

And with this i think you're set to go. For further information and functions to be used of the result look up DOMElement ( http://php.net/manual/de/class.domelement.php ). With this information you should be able to grab all that. But my question is:
Why doing this so complicated, i don't really see a use-case for doing this. As the title and everything else should be something coming from the database? And if it's an XML there's better solutions than relying on Dom_Query.

Anyways, if this was helpful to you please accept and/or vote the answer.
