希望您可以幫助PHP新手（向我展示C＃，我很好！）。在PHP中使用XPath篩選XML數據（使用名稱空間）
我想過濾基於PHP變量的XML數據。下面是我的XML文件的切割：

我得到2個PHP變量從
$category = $_POST['category'];
$region = $_POST['region'];
我希望能夠根據這些變量來過濾我的XML，但無法弄清楚如何做它。請注意，我的XML中的區域和類別節點前面有一個名稱空間。
這裏是我的（很基本的，所以不要笑）PHP
<?php
$xml = simplexml_load_file("jobs-rss.xml");
if(isset($_POST['category']) && isset($_POST['region']))
{
$category = $_POST['category'];
$region = $_POST['region'];
$html = '';
if($category == "All" && $region == "All")
{
// Load all jobs
foreach($xml->channel->item as $item){
$ns = $item->children('https://itrent-web1.midlandsco-op.com/tlive_webrecruitment/wrd/run/../../webrecRSS.dtd');
$html .= "<h2>" . $item->title . "</h2>";
$html .= "<p><strong>Reference: </strong>" . $ns->reference . "</p>";
$html .= "<p>" . $ns->description . "</p>";
$html .= "<p><strong>Salary: </strong>" . $ns->salary . "</p>";
$html .= "<p><strong>Region: </strong>" . $ns->region . "</p>";
$html .= "<p><strong>Location: </strong>" . $ns->location . "</p>";
$html .= "<p><strong>Category: </strong>" . $ns->category . "</p>";
$html .= "<p><strong>Closing Date: </strong>" . $ns->closingdate . "</p>";
$html .= "<p><a href='" . $item->link . "'>Click here to apply for this job</a></p>";
}
}
else
{
// Filter my XML here based on a combination of the $category and $region varaibles
}
}
echo $html;
?>
任何幫助將不勝感激。

你是什麼意思的「過濾器」？ –
