>Hi,

>I have a XML file being used by an .NET application. The XML file contains HTML code. The HTML code uses " " (if UT does not show this correctly it should be "epershand" + "nbsp" + "semicolon"). But the .NET application gives error "reference to undeclared entity 'nbsp'". How do I show this entity in the XML so that .NET will not give an error? I suspect that the concept of "predefined entity" should be used but I don't know how.

How exactly you're using this XML? It sounds to me you need to use some strandard EnCode function with this XML file.

Check EnCode XML
