I know how to remove namespaces at all but what I need to do is only to remove specific namespace prefixes eg transform this file (removing xenc prefixes):

```
<?xml version="1.0" encoding="UTF-8"?>
<xenc:EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element" xmlns:xenc="http://www.w3.org/2001/04/xmlenc#">
<xenc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes256-cbc"/>
<ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
    <xenc:EncryptedKey xmlns:xenc="http://www.w3.org/2001/04/xmlenc#">
        <xenc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5"/>
    </xenc:EncryptedKey>
    <ds:X509Data>
        <ds:X509Certificate>AAA=</ds:X509Certificate>
    </ds:X509Data>
</ds:KeyInfo>

```

into this:

```
<?xml version="1.0" encoding="UTF-8"?>
<EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element" xmlns="http://www.w3.org/2001/04/xmlenc#">
<EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes256-cbc"/>
<ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
    <EncryptedKey xmlns:xenc="http://www.w3.org/2001/04/xmlenc#">
        <EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5"/>
    </EncryptedKey>
    <ds:X509Data>
        <ds:X509Certificate>AAA=</ds:X509Certificate>
    </ds:X509Data>
</ds:KeyInfo>

```

Can you help me how it could be done using XSLT?
