    Possibly, but you didn't get that XML from the site.
    The XML you mention can't be validated, because there
    is no limit on the element tags. You want to encode
    the DKRid as an attribute, not as string. Giving you
    something like:
      <node DKRid="...">content</node>

    Where "node" might also be <body> or one of the other
    element tags identified in the article. Those are all
    encoding issues, though, that are solvable when we get
    to that point. wrote:
