    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // The signed XML to be verified in this example contains the following:

    // <?xml version="1.0" encoding="ISO-8859-1"?>
    // <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
    // <Documento ID="F13T34">
    // ...
    // </Documento>
    // <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
    // ....
    // </Signature>
    // </DTE>

    // Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1 
    sbXml = CkStringBuilder_Create();
    success = CkStringBuilder_LoadFile(sbXml,"qa_data/xml_dsig/sii_cl/signed1.xml","iso-8859-1");
