Closed gabbian1 closed 6 years ago

Hello,

I have a question about create an signature in xml using this tool, how can I to do it?

Thanks,

Pacheco.

Do you have a schema (xsd) for the xml document that you need to create? If so you can use erlsom:write/2 (or erlsom:write/3).

erlsom:write(Data, Model).

Data is the Erlang representation of your signature (in the form of a record). Model is the internal representation of the XSD.

To get the Model you need to compile your schema: erlsom:compile_xsd(Xsd).

You can get the definitions of the record format (a .hrl file) that you must use to specify the Data by using erlsom:write_xsd_hrl_file/3.

If you do not have an xsd, then you can probably not really use erlsom to create an XML file.

Good luck, Willem

Hi @willemdj,

Thanks for explain :)

Data is the Erlang representation of your signature (in the form of a record). Model is the internal representation of the XSD.

It can be a data signed by a certificate ? My requeriment is prepare a xml file (also by XSD schema) and sign it by a especific certificate.

Br,

If you simply need to sign the XML document, you can do that after encoding it with erlsom. If there are other requirements (like the XML needing to be in canonical form, ...) then I don't know, you'll have to figure it out yourself...

Good luck, Willem

Okay, I'll try it (And close this issue) ;)

All best to you too!
