如想屏蔽掉cms pages相关的单页面，首页在/app/code/core/Mage/Sitemap/Model这个路径下找到Sitemap.php，打开以后找到Generate cms pages sitemap（大概在171行左右）原文如下
/**
* Generate cms pages sitemap
*/
$changefreq = (string)Mage::getStoreConfig('sitemap/page/changefreq', $storeId);
$priority = (string)Mage::getStoreConfig('sitemap/page/priority', $storeId);
$collection = Mage::getResourceModel('sitemap/cms_page')->getCollection($storeId);
foreach ($collection as $item) {
$xml = sprintf('<url><loc>%s</loc><lastmod>%s</lastmod><changefreq>%s</changefreq><priority>%.1f</priority></url>',
htmlspecialchars($baseUrl . $item->getUrl()),
$date,
$changefreq,
$priority
);
$io->streamWrite($xml);
}
unset($collection);
