Could someone kindly help me get this parsed. I have the following XML. I need to get the value of photo-url that matches "75" max-width. How do I filter that in PHP $xml->posts->post['photo-url']....?

<photo-url max-width="100">
image1.jpg
</photo-url>

<photo-url max-width="75">
image2.jpg
</photo-url>

推荐答案

使用 SimpleXMLElement 和 xpath 查询.

Use SimpleXMLElement and an xpath query.

$xml = new SimpleXMLElement($your_xml_string);
$result = $xml->xpath('//photo-url[@max-width="75"]');

// Loop over all the <photo-url> nodes and dump their contents
foreach ($result as $node ) {
   print_r($node);
   $image = strip_tags($node->asXML);
}
