Properties

Id — ID for this document element

character vector | string scalar

ID for this document element, specified as a character vector or string scalar. The DOM generates a session-unique ID when it creates the document element. You can specify your own ID.

Source — Source object from which the message originates

a DOM object

Source DOM object from which the message originates.

Tag — Tag for this document element

character vector | string scalar

Tag for this document element, specified as a character vector or string scalar.

The DOM generates a session-unique tag as part of the creation of this object. The generated tag has the form CLASS:ID, where CLASS is the object class and ID is the value of the Id property of the object. Specifying your own tag value can help you to identify where an issue occurred during document generation.

Text — Text of message

character vector

Message text, specified as a character vector.

Methods

l = addlistener(dispatcher,'Message', ...
      @(src, evtdata) disp(evtdata.Message.formatAsText));
     
open(d);
