本站案例
本站SiteMap的XML格式：https://www.svlik.com/sitemap.xml
本站SiteMap的HTML格式：https://www.svlik.com/sitemap.html
本站MIPSiteMap的XML格式：https://www.svlik.com/mip_sitemap.xml
准备工作
首先创建一个文件夹名为Svlik-SiteMap，然后在文件夹内创建3个文件，名字分别为sitemap.html、Svlik-SiteMap.php、Svlik-SiteMap-Function.php即可。
写入代码
将以下代码填入对应的文件中即可。

将以上代码按照文件名对应输入之后将会是以下图片效果，然后将整个文件上传至/wp-content/plugins/文件夹内，然后到后台启用插件即可正常使用，再把根目录设置可写即可正常生成了。
如果你不会自己动手，没关系，伸手党可以在底部直接下载即可。
