Question

我正在使用此代码打印原子网络Feed。如何访问链接rel ='enclosure'中的一个图像？有人可以帮我吗？我只想在屏幕上打印一个图像，但我不知道如何访问四个链接属性之一。我已经搜索了信息，但它似乎没有帮助我。

<?php

    // read in an xml file
      $myFile = "http://www.deredactie.be/cm/vrtnieuws?mode=atom";

    $feed = simplexml_load_file($myFile);

    $xml =  $feed->children('http://www.w3.org/2005/Atom');

    echo "<h1>".$xml->title . "</h1>\n";

    foreach ($xml->entry as $entries) {
        $child = $entries->children('http://www.w3.org/2005/Atom');
        // post title
        echo "<h3>".$child->title . "</h3>\n";
        // post author

        // post content
        if (!empty($child->summary)) echo htmlspecialchars($child->summary) . "<br />\n";
        echo $child->content->asXML();
        echo $child->updated;
        echo $child->link;
    }

?>

Answer 1

对不起，我在手机上，所以我不能语法

$result = $child->xpath('//link[@rel=\'enclosure\']');
while(list( , $node) = each($result)) {
    echo "<img src='{$node['@href']}' />";
}

由于你有超过1个链接，所以回显$ child-＆gt;链接

是很奇怪的
