| 1. A computer-implemented method for preserving unknown XML-based elements so that the unknown XML-based elements are not
dropped when reading XML-based markup into a memory in a strongly typed environment, wherein the method is implemented by
a processor executing computer-executable instructions stored in a memory, the method comprising:
in a strongly typed environment:
receiving XML-based markup that may contain XML-based elements that are both known and unknown;
instantiating a strongly typed tree that is associated with the known XML-based elements;
instantiating a weakly typed tree that is associated with both the XML-based known and unknown elements, wherein the act of
instantiating a weakly typed tree comprises:
for every known element in the XML-based markup, creating a placeholder node in the weakly typed tree; and
for every unknown element in the XML-based markup, creating a node that preserves the unknown markup; and
correlating the strongly type tree and the weakly typed tree by populating the weakly typed tree with objects or nodes from
the strongly typed tree in a manner that preserves the unknown XML-based elements.
