sitemap.xml生成方法(asp和php)

sitemap.xml文件格式如下：

<?xml version=”1.0″ encoding=”UTF-8″ ?>
<urlset xmlns=”http://www.sitemaps.org/schemas/sitemap/0.9“>
<url>
<loc>http://web.it168bbs.com/<;/loc>
<lastmod>2009-04-27</lastmod>
<changefreq>daily</changefreq>
</url>
<url>
<loc>http://web.it168bbs.com/index.asp<;/loc>
<lastmod>2009-04-27</lastmod>
<changefreq>weekly</changefreq>
</url>
</urlset>

那怎么制作sitemap.xml。最笨的方法就是按照这六个标签的规则，自己手写了。

如果网站的页面太多了，这个就会变成了一个超级郁闷的体力劳动。于是就有不少sitemap.xml的生成工具出现了，但是现在大部分的sitemap.xml生成工具都是在客户端输入网址，让工具在网站自行寻找链接生成，这样的模式，Rookie感觉效率比较低，而且没有办法对生成链接做控制。终于在网上找到了一个比较好的方法，适用于将内容生成静态页面的网站。有人将生成sitemap.xml的功能，写成了asp和php的页面，在页面上可以控制需要生成哪些链接。按照你的需要修改页面后，再把页面上传到你的网站空间，访问这个页面就是你所需要的sitemap.xml文件。然后就保存成为xml文件格式，再上传到你的空间，再将链接提交给支持sitemap.xml的搜索引擎。
