这是我的代码:
$rss = new DOMDocument();
$rss->load('http://www.bing.com/news/search?q=obama&format=rss');
$feed = array();
foreach ($rss->getElementsByTagName('item') as $node) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'image' => $node->getElementsByTagName('News:Image')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
);
array_push($feed, $item);
}
$limit = 1;
for($x=0;$x<$limit;$x++) {
$title = str_replace(' & ', ' & ', $feed[$x]['title']);
$link = $feed[$x]['link'];
$description = $feed[$x]['desc'];
$date = date('l F d, Y', strtotime($feed[$x]['date']));
echo '<item>';
echo '<title>'.$title.'</title>';
echo '<link>'.$link.'</link>';
echo '<description>'.$description.'</description>';
echo '<News:Image>'.$image.'</News:Image>';
echo '<pubDate>'.$date.'</pubDate>';
echo '</item>';
}
我无法在标签 新闻:图片 中提取图片网址,其余的都可以
Feed输出位于此link
中答案 0 :(得分:0)
在输出部分,您没有定义变量$image
,而您需要搜索的标记是@u_mulder所说的Image。以下内容包含了这些更改,并且似乎输出了所需的结果: -
$rss = new DOMDocument();
$rss->load('http://www.bing.com/news/search?q=obama&format=rss');
$feed = array();
foreach ( $rss->getElementsByTagName('item') as $node ) {
$item = array (
'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
'image' => $node->getElementsByTagName('Image')->item(0)->nodeValue,
'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
);
array_push($feed, $item);
}
$limit = count( $feed );
for( $x=0; $x < $limit; $x++ ) {
$title = str_replace(' & ', ' & ', $feed[$x]['title']);
$link = $feed[$x]['link'];
$description = $feed[$x]['desc'];
$date = date('l F d, Y', strtotime($feed[$x]['date']));
$image = $feed[$x]['image'];
echo '<item>';
echo '<title>'.$title.'</title>';
echo '<link>'.$link.'</link>';
echo '<description>'.$description.'</description>';
echo '<Image>'.$image.'</Image>';
echo '<pubDate>'.$date.'</pubDate>';
echo '</item>';
}
