我使用php使用以下代码生成xml站点地图：
$number = $_GET['number'];
$sitemap = 'http://example.com/'.$number.'.txt';
$domain = $_SERVER['SERVER_NAME'];
$last_modification = "17.05.2018";
$change_frequency = "daily";
$priority = "1";
$content = file_get_contents($sitemap);
$content = str_replace("\r", "", $content);
$links = explode("\n", $content);
ob_start();
echo '<?xml version="1.0" encoding="UTF-8"?>'. "\n";
echo '<?xml-stylesheet type="text/xsl" href="http://'.$domain.'/sitemap.xsl"?>' ."\n";
echo '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns:mobile="http://www.google.com/schemas/sitemap-mobile/1.0" xmlns:xhtml="http://www.w3.org/1999/xhtml">'. "\n";
foreach($links as $link) {
$link = str_replace(" ", "-", $link);
$link.=".pdf";
?>
<url>
<loc><?php echo 'http://'.$domain.'/0/'.$link; ?></loc>
<lastmod><?php echo $last_modification; ?></lastmod>
<changefreq><?php echo $change_frequency; ?></changefreq>
<priority><?php echo $priority; ?></priority>
</url>
<?
}
echo '</urlset>';
$file_contents = ob_get_contents();
ob_end_clean();
echo $file_contents;
它只是从位于某处的txt链接文件生成xml站点地图。我面临的问题是<?xml-stylesheet type="text/xsl" href="http://'.$domain.'/sitemap.xsl"?>没有将样式和布局应用到我的xml中。地址是正确的，如果我上传只是生成的xml文件到服务器上的文件一切正常，但一旦我尝试在线生成它只是未格式化的站点地图。
供您参考，请在下面找到xls代码：
