Blogger question - Error message

[contentmaster]

A post on my blog is showing up in search results with the following message :

"This XML file does not appear to have any style information associated with it. The document tree is shown below."

Below this message, the entire html coding is showing...I am not sure what I may have done wrong to get such a message?

Any help will be appreciated..If this is not the place for this question, please excuse me and guide me in the right direction.

Which browser are you using when you see this, or is it with every browser? It sounds like the page is being sent as XML rather than HTML (ie. a wrong MIME type). Are you using XHTML?

Well, I see the same message and the same html coding on both Firefox and IE....I came across this problem when I was doing a Google search on the topic. Doing so, shows the page in the top 10 results but it is of no use as it appears as a block of junk coding.
