Yes, I know the hash will be calculated when generating a signature.
However, it will be troublesome since at least a private key and a
certificate will be needed. ( I tried to use RSA_NONE when calling
createBlankSignature, but I've got No signing algorithm exception
afterwards).
Actually there's a API class XSECC14n20010315 can do the
canonicalization job, which is just not well documented. I found a
sample binary "c14n" in xml-security-c source code and it's actually
very easy. Now I've got correct result.
Thank you all.

I don't know what you mean by that exactly, but the library can canonicalize
a DOM node and it can produce a hash internally when it's generating a
signature, but you'd have to mess around with the internal APIs to get it to
generate a hash explicitly I believe.
