【问题描述】:
我只想获取“频道”标签的名称,即频道……当我使用它来解析来自 Google 的 rss 时,该脚本工作正常…………但是当我将它用于其他一些提供程序,它提供输出“#text”而不是提供预期输出的“通道”……以下是我的脚本,请帮助我。
$url = 'http://ibnlive.in.com/ibnrss/rss/sports/cricket.xml';
$get = perform_curl($url);
$xml = new DOMDocument();
$xml -> loadXML($get['remote_content']);
$fetch = $xml -> documentElement;
$gettitle = $fetch -> firstChild -> nodeName;
echo $gettitle;
function perform_curl($rss_feed_provider_url){
$url = $rss_feed_provider_url;
$curl_handle = curl_init();
// Do we have a cURL session?
if ($curl_handle) {
// Set the required CURL options that we need.
// Set the URL option.
curl_setopt($curl_handle, CURLOPT_URL, $url);
// Set the HEADER option. We don't want the HTTP headers in the output.
curl_setopt($curl_handle, CURLOPT_HEADER, false);
// Set the FOLLOWLOCATION option. We will follow if location header is present.
curl_setopt($curl_handle, CURLOPT_FOLLOWLOCATION, true);
// Instead of using WRITEFUNCTION callbacks, we are going to receive the remote contents as a return value for the curl_exec function.
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, true);
// Try to fetch the remote URL contents.
// This function will block until the contents are received.
$remote_contents = curl_exec($curl_handle);
// Do the cleanup of CURL.
curl_close($curl_handle);
$remote_contents = utf8_encode($remote_contents);
$handle = @simplexml_load_string($remote_contents);
$return_result = array();
if(is_object($handle)){
$return_result['handle'] = true;
$return_result['remote_content'] = $remote_contents;
return $return_result;
}
else{
$return_result['handle'] = false;
$return_result['content_error'] = 'INVALID RSS SOURCE, PLEASE CHECK IF THE SOURCE IS A VALID XML DOCUMENT.';
return $return_result;
}
} // End of if ($curl_handle)
else{
$return_result['curl_error'] = 'CURL INITIALIZATION FAILED.';
return false;
}
}
