I have crated XML site through online xml sitemap genrator, but when i was editing my XML site map, i m confused with the following code: <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"> Can anyone explain me what does this code mean, if i remove from my sitemap code is there any negative impact?
You could cut it down to something like '<urlset xmlns="http://www.google.com/schemas/sitemap/0.90">'. urlset is just the encapsulating element of all the URLs, the xmlns attribute defines the schema that the sitemap adheres to.
