Hi,
The second example you present is not a well-formed XML document,
because there are space characters before the prolog, and any
conforming XML parser will fail to parse such a document.
The grammer of an XML document starts with:
document ::= prolog element Misc*
prolog ::= XMLDecl? Misc* (doctypedecl Misc*)?
XMLDecl ::= '<?xml' VersionInfo EncodingDecl? SDDecl? S? '?>'
Note that there is no optional space characters declared before the
"XMLDecl". The start of an XML document MUST begin with a '<'
character encoded in a Unicode character encoding, such as UTF-8 or
UTF-16.
What HTTP client are you using? and why is it adding spaces before the
XML document?
Paul.
