PHP変数に基づいてXMLデータをフィルタリングする必要があります。ここに私のXMLファイルのカットです：

... etc - other <item> nodes follow
私は
$category = $_POST['category'];
$region = $_POST['region'];
から2 PHP変数を取得し、私はこれらの変数に基づいて、私のXMLをフィルタリングすることができるようにしたいが、実行する方法を見つけ出すことはできませんそれ。私のXMLの領域ノードとカテゴリノードの前には名前空間があることに注意してください。
は、ここに私（そう笑っていない非常に基本的な）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;
?>
だ任意の助けいただければ幸いです。
おかげで、 ブレット
「フィルタ」とはどういう意味ですか？ –
