使用php在depth2中查找rss源
这是我的代码:使用php在depth2中查找rss源,php,rss,Php,Rss,这是我的代码: <?php $location = 'http://timesofindia.indiatimes.com//'; $html = file_get_contents($location); echo getRSSLocation($html, $location); # http://hakre.wordpress.com/feed/ /** * @link http://keithdevens.com/weblog/archive/2002/Jun/03/RSSA
<?php
$location = 'http://timesofindia.indiatimes.com//';
$html = file_get_contents($location);
echo getRSSLocation($html, $location); # http://hakre.wordpress.com/feed/
/**
* @link http://keithdevens.com/weblog/archive/2002/Jun/03/RSSAuto-DiscoveryPHP
*/
function getRSSLocation($html, $location){
if(!$html or !$location){
return false;
}else{
#search through the HTML, save all <link> tags
# and store each link's attributes in an associative array
preg_match_all('/<link\s+(.*?)\s*\/?>/si', $html, $matches);
$links = $matches[1];
$final_links = array();
$link_count = count($links);
for($n=0; $n<$link_count; $n++){
$attributes = preg_split('/\s+/s', $links[$n]);
foreach($attributes as $attribute){
$att = preg_split('/\s*=\s*/s', $attribute, 2);
if(isset($att[1])){
$att[1] = preg_replace('/([\'"]?)(.*)\1/', '$2', $att[1]);
$final_link[strtolower($att[0])] = $att[1];
}
}
$final_links[$n] = $final_link;
}
#now figure out which one points to the RSS file
for($n=0; $n<$link_count; $n++){
if(strtolower($final_links[$n]['rel']) == 'alternate'){
if(strtolower($final_links[$n]['type']) == 'application/rss+xml'){
$href = $final_links[$n]['href'];
}
if(!$href and strtolower($final_links[$n]['type']) == 'text/xml'){
#kludge to make the first version of this still work
$href = $final_links[$n]['href'];
}
if($href){
if(strstr($href, "http://") !== false){ #if it's absolute
$full_url = $href;
}else{ #otherwise, 'absolutize' it
$url_parts = parse_url($location);
#only made it work for http:// links. Any problem with this?
$full_url = "http://$url_parts[host]";
if(isset($url_parts['port'])){
$full_url .= ":$url_parts[port]";
}
if($href{0} != '/'){ #it's a relative link on the domain
$full_url .= dirname($url_parts['path']);
if(substr($full_url, -1) != '/'){
#if the last character isn't a '/', add it
$full_url .= '/';
}
}
$full_url .= $href;
}
return $full_url;
}
}
}
return false;
}
}
/si',$html,$matches);
$links=$matches[1];
$final_links=array();
$link\u count=计数($links);
对于($n=0;$nW)你为什么使用正则表达式来解析rss?你应该使用类似Ok的东西,好吧,我不会使用正则表达式,但我的问题不是,我必须在网站的内部选项卡中找到rss提要,你能告诉我怎么可能吗。我想stackoverflow中没有开发人员来解决这个问题。很遗憾,我无法得到任何答案,谢谢
