Hi,
Suppose I am using Sax callbacks for parsing, in that case if I want to
know the encoding specified in the xml declaration, I will try to retrieve
it from ctxt->encoding, however ctxt->encoding is set to only UTF-8 or
UTF-16, depending on whichever is specified in the xml declaration. In case
the xml declaration specifies any other encoding, for instance GB2312, then
ctxt->encoding will be NULL, while ctxt->input->encoding will be set to
GB2312.
My doubt is in the function xmlParseEncodingDecl, ctxt->encoding is not set
to the encoding specified in the xml declaration if its not UTF-8 or
UTF-16...
The function checks if the encoding specified in the xml declaration is
UTF-8 or UTF-16, and sets ctxt->encoding if that is the case else it sets
ctxt->input->encoding to the encoding specified in the xml declaration while
ctxt->encoding is NULL.
Is there any specific reason for this?
