Validate XML signature
I Have a problem with a Signature validator to XML file, when this file have more than one Signature tag.
Like This
<nfeProc xmlns="http://www.portalfiscal.inf.br/nfe" versao="4.00">
<NFe>
<infNFe Id="NFexxx" versao="4.00">
...
</infNFe>
<Signature xmlns="http://www.w3.org/2000/09/xmldsig#">

This is my method of validation
Validate(file,element,clazz) ;
new reader,sc,data,xmlSignature
;
set sc=reader.OpenFile(file)
quit:$$$ISERR(sc) sc
; get elementet
do reader.Correlate(element,clazz)
if 'reader.Next(.data,.sc){
quit sc
}
;
do reader.Correlate("Signature","%XML.Security.Signature")
if 'reader.Next(.xmlSignature,.sc) {
quit sc
}
;
quit xmlSignature.ValidateDocument(data)
I Get this error when to try call Validate("file.xml","NFe","class")
<METHOD DOES NOT EXIST>zValidateElement+35^%XML.Security.Signature.1 *GetNode "class"
