废话不多说，直接上代码

<?php

require('./wp-blog-header.php');

header("Content-type: text/xml");

header('HTTP/1.1 200 OK');

$posts_to_show = 1000; // 获取文章数量

echo '<?xml version="1.0" encoding="UTF-8"?>';

echo '<urlset xmlns:xsi="<a href="http://www.w3.org/2001/XMLSchema-instance" rel="external nofollow" >http://www.w3.org/2001/XMLSchema-instance</a>" xmlns="<a href="http://www.sitemaps.org/schemas/sitemap/0.9" rel="external nofollow" rel="external nofollow" >http://www.sitemaps.org/schemas/sitemap/0.9</a>"

xsi:schemaLocation="<a href="http://www.sitemaps.org/schemas/sitemap/0.9" rel="external nofollow" rel="external nofollow" >http://www.sitemaps.org/schemas/sitemap/0.9</a> <a href="http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">'" rel="external nofollow" >http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">'</a>;

?>

<?php
