func chilkatTest() {
    let cert = CkoCert()

    var success: Bool = cert.LoadFromFile("qa_data/certs/testIcpBrasil.cer")
    if success == false {
        print("\(cert.LastErrorText)")
        return
    }

    // If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
    // then the Rfc822Name property returns XML.
    var subjectAltNameXml: String? = cert.Rfc822Name

    print("\(subjectAltNameXml!)")

    // Here's a sample of the subjectAltNameXml:

    // <SubjectAltName>
    //     <name type="oid" oid="2.16.76.1.3.4">290999653223955019700000000000000000000150424SRJUXPTS</name>
    //     <name type="oid" oid="2.16.76.1.3.2">JOAO SILVA</name>
    //     <name type="oid" oid="2.16.76.1.3.3">02408939000115</name>
    //     <name type="oid" oid="2.16.76.1.3.7">000000000000</name>
    // </SubjectAltName>

    // The XML can be parsed like this:

    let xml = CkoXml()
    xml.LoadXml(subjectAltNameXml)

    var oid: String?
    var name: String?

    var i: Int = 0
    var count_i: Int = xml.NumChildrenHavingTag("name").intValue
    while i < count_i {
        xml.I = i
        oid = xml.ChilkatPath("name[i]|(oid)")
        name = xml.GetChildContent("name[i]")
        print("\(oid!): \(name!)")
        i = i + 1
    }
