string to xhtml

Is there a way to take a string and make it xhtml compliant? The string may contain ampersand and non breaking spaces ( ). My ajax response is bombing on a string containing a non breaking space ( ). So, is there a function that will take a string as input and return it as valid xhtml?

You can try Server.HTMLEncode( string )

I don't see how it would blow up on the " " because there is nothing invalid about this, specifically in regards to Xhtml.

Other than that you are probably going to have to write your own function to replace characters properly.

I discovered that XML does not recognize . Instead, you have to add a document type to the top of your XML:

<!DOCTYPE stylesheet [<!ENTITY nbsp " ">

This fixes the problem.
