Does the cmsContentXml table contain the latest version (approved) content for a given document id?

I can see how it has a xml column that has the entire document in xml format, I am wondering if this is the main table that umbraco lookups to fetch a document?

If I have a non-umbraco website, but want to fetch content and display it on this website, can I just hackishly poke into this table and fetch the html by parsing the xml?

I don't want to go through a web service (this is a short term hack until we setup umbraco properly).
