Caché Upgrade Checklists - InterSystems Documentation

Operators
1.2.7 Class Changes
1.2.7.1 %Library.String
The LogicalToDisplay method has been changed in this version. In converting the internal form to
an external representation, it removes all NUL ($CHAR(0)) characters from the string. This contradicts
the usual expectation that LogicalToDisplay and DisplayToLogical are inverses of one another.
1.2.7.2 %XML.Document and %XML.Node
This version of Caché introduces the %XML.Document class that represents an XML document as a
Document Object Model (DOM). The DOM may be created either
• from an XML document by accessing the Document property of %XML.Reader after calling an
Openxxx method of %XML.Reader
.
• as a new instance by calling the CreateDocument method to instantiate an empty document.
The document can be written to a destination with the various Writer and Tree methods of %XML.DOM.
The %XML.Node class is used to access the components of the DOM. %XML.Node navigates through
the nodes of the DOM rather than representing a fixed node in a DOM tree. The MoveToxxx methods
are used to move through the DOM. The properties and methods of %XML.Node are then used to
retrieve and modify the node contents.
Note:
A set of macros in the file, %xmlDOM.inc may also be used to navigate the DOM based on
the DocumentId property of %XML.Document.
