erro loadxml on firefox


good moorning.

I´ve a app wich load a xml retult from *.asp.

In IE its fine, ok, its works. But in firefox give an error :

Error type:LoadXML

Description : Incorrect XML

Any can give me the light"?!!?

Thanks for all!

Most probably you have some whitespaces before start of XML, in case of FF any output(even whitespaces or newlines)  before <?xml declaration will cause such error
