preserve the signature at serialization

[Anonymous]

Hi,
i have a problem with moment that nusoap serialize the envelope, he modify the signature values like that:

original value

<Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
            <SignedInfo>
                <CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/>
                <SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"/>
                <Reference URI="#Lote">
                    <Transforms>
                        <Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/>
                    </Transforms>
                    <DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/>
                    <DigestValue></DigestValue>
                </Reference>
            </SignedInfo>
            <SignatureValue></SignatureValue>
            <KeyInfo>
                <X509Data>
                    <X509Certificate></X509Certificate>
                </X509Data>
            </KeyInfo>
        </Signature>

result value

<Signature>
    <SignedInfo>
        <CanonicalizationMethod xmlns="http://www.w3.org/2000/09/xmldsig#"></CanonicalizationMethod>
        <SignatureMethod xmlns="http://www.w3.org/2000/09/xmldsig#"></SignatureMethod>
        <Reference xmlns="http://www.w3.org/2000/09/xmldsig#">
            <Transforms xmlns="http://www.w3.org/2000/09/xmldsig#">
                <Transform xmlns="http://www.w3.org/2000/09/xmldsig#"></Transform>
            </Transforms>
            <DigestMethod xmlns="http://www.w3.org/2000/09/xmldsig#"></DigestMethod>
            <DigestValue xmlns="http://www.w3.org/2000/09/xmldsig#"></DigestValue>
        </Reference>
    </SignedInfo>
    <SignatureValue></SignatureValue>
    <KeyInfo>
        <X509Data xmlns="http://www.w3.org/2000/09/xmldsig#">
            <X509Certificate></X509Certificate>
        </X509Data>
    </KeyInfo>
</Signature>
