# Using Dynamic URLs with more than one Variable in a Sitemap?

I have a site map with generated dynamic urls that I need included in the sitemap. However, the sitemap seems to be generating an error on the & character, so that pages with more than one variable in the query string break the sitemap. How can I fix this? Here's an example:

http://example.com/index.php?action=view&id=10

The ampersand (&) character is a reserved character in XML (sitemaps are XML) and must be replaced with an XML entity that represents it. In this case that would be &amp; (all entities start with ampersand which is why it is reserved).
When the XML is parsed the &amp; entity in your url will be translated into plain &.
