Question

I am trying to build a function to render sitemap links and get inside links of inner sitemap its working good but its not working for all the links some of the links ( with the same syntax) is not working and responding errors
function download_page($path){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$path);
curl_setopt($ch, CURLOPT_FAILONERROR,1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 Safari/537.36',
'Content-type: application/xml'
]);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
$retValue = curl_exec($ch);
curl_close($ch);
return $retValue;
}
function getAllLinks($sitemapUrl) {
$links = array();
$i=0;
// $context = stream_context_create(array('http' => array('header' => 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 Safari/537.36')));
// $xml = file_get_contents($sitemapUrl, false, $context);
$sitemap = $this->download_page($sitemapUrl);
// dd($sitemap);
// Load the sitemap XML file
$sitemapXml = new \SimpleXMLElement($sitemap);
// $sitemapXml = simplexml_load_file($sitemap);
// $sitemapXml = simplexml_load_string($sitemap);
// Loop through the <url> and <sitemap> elements
foreach($sitemapXml->children() as $child) {
if ($child->getName() === 'url') {
$i++;
$links[$i]['url'] = (string)$child->loc;
$links[$i]['lastmod'] = (string)$child->lastmod;
}
elseif ($child->getName() === 'sitemap') {
$links = array_merge($links, $this->getAllLinks((string)$child->loc));
}
}
return $links;
}
In the comments I tried to u se multiple methods
Example for working link : https://rulepingpong.com/sitemap_index.xml
Example for not working link: https://majesticgaragedoorfl.com/sitemap_index.xml
getting the error "String could not be parsed as XML"
I am really lost
