Trying understanding (Xml NS question)

[Renato Tegon Forti]

Hi All,

 

I need help!

I have one document, like this:

 

<?xml version="1.0" encoding="UTF-8"?>

 

   <nfeProc versao="1.10"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:ds="http://www.w3.org/2000/09/xmldsig#";
xmlns="http://www.portalfiscal.inf.br/nfe";>

      <NFe xmlns="http://www.portalfiscal.inf.br/nfe";>

        <infNFe versao="1.10"
Id="NFe35090956724412000129550030000000012522555008"> // ...

        <Signature xmlns="http://www.w3.org/2000/09/xmldsig#";> // ...

      </NFe>

   </nfeProc>

 

In this case the the signature checks fail!

 

If I remove the NS:

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:ds="http://www.w3.org/2000/09/xmldsig#";

 

Like this:

 

<?xml version="1.0" encoding="UTF-8"?>

 

   <nfeProc versao="1.10" xmlns="http://www.portalfiscal.inf.br/nfe";>

      <NFe xmlns="http://www.portalfiscal.inf.br/nfe";>

        <infNFe versao="1.10"
Id="NFe35090956724412000129550030000000012522555008"> // ...

        <Signature xmlns="http://www.w3.org/2000/09/xmldsig#";> // ...

      </NFe>

   </nfeProc>

 

The signature is validated OK!

 

Why? I 'am trying understanding! What I must do to work with NS
(xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:ds="http://www.w3.org/2000/09/xmldsig#";)

 

Thanks
