This example creates a PBDOM_DOCUMENT based
on the following DOM tree:

The PowerScript code obtains the root element, uses it to
obtain the child element, and then obtains an array of the child
element’s own children. This array has a single item, the
PBDOM_TEXT object with the text Data. The array can be
cast to a PBDOM_CHARACTERDATA object because it does not
contain any objects that are not derived from PBDOM_CHARACTERDATA,

The call to GetOwnerDocumentObject returns
a PBDOM_OBJECT, which is stored in a PBDOM_DOCUMENT
called pbdom_owner_doc. The
call to Equals tests whether the owner document
of the “Data” PBDOM_TEXT and the main
document, referenced using pbdom_doc,
refer to the same document.

This example creates a PBDOM_DOCUMENT based
on the same DOM tree as example 1. It creates a PBDOM_TEXT,
stores it in the PBDOM_CHARACTERDATA variable pbdom_chardata,
and assigns it some text. Objects created in this way are standalone
objects—they have no owner document or parent. Calling GetOwnerDocumentObject on pbdom_chardata returns null.

The code then adds pbdom_chardata as
a child to the data element. This implicitly imports pbdom_chardata into
the original document. pbdom_chardata now
has an owner document and a parent (the data element). Calling GetOwnerDocumentObject on pbdom_chardata returns
the original document. When the returned PBDOM_DOCUMENT
has been assigned into pbdom_owner_doc,
a call to Equals to compare pbdom_doc with pbdom_owner_doc returns
true:
