Re: [bdbxml] Limitations of XMLModify

Konrad,

There are two variants of XmlModify::execute().  One takes an XmlValue
(single context item) argument and the other takes an XmlResult  
(multiple
context items) argument.

If you first construct a separate query that returns the root nodes  
of the
target documents for your update, that XmlResult object can
be used as the input to XmlModify::execute(XmlResult &, ...)

Regards,

George
