  libxml2 does not support DOM c.f. the main page:
    http://xmlsoft.org/

    "To some extent libxml2 provides support for the following additional specifications but doesn't claim to 
implement them completely:

        * Document Object Model (DOM) http://www.w3.org/TR/DOM-Level-2-Core/ the document model, but it 
doesn't implement the API itself, gdome2 does this on top of libxml2"

  Answer is no. DOM is not a good API for the C language.

  libxml2 does not support Encryption not Digital Signature.
  XMLSec does support Encryption and Digital Signature using libxml2
libxslt and various othe cryptographic libraries.
