Extraer el valor de signatureValue id

[ialvira]

hola luis:

estoy usando tu libreria para firmar documentos xml en formato xades/epes y los firma correctamente.

el siguiente paso es una vez firmado extraer el SignatureValue id del archivo xml ya firmado

he intentado acceder con un document.getElementsByTagName("Signature") pero me devuelve null quiza es por que mi xsd no integra la firma

puedo usar tu libreria para extraer el signatureValue aunque haya que extraelo del signer??

gracias

Hello Luis I am using your library to sign xml documents in xades / epes and the signature correctly. the next step is once signed extract the SignatureValue id from the xml file already signed He tried to access a document.elementsByTagName ("Signature") but it returns null if it is for that my xsd does not integrate the signature Can I use your library to extract the signature Value even if it has to be extracted from the signer? Thank you

Hello,

Try setting the document build factory to be namespace aware: dbFactory.setNamespaceAware(true).

Note: this isn't really an issue with xades4j...
