Accessing elements in a message in the MRM domain

You can use ESQL to manipulate the logical tree that represents a message in the message flow. This topic describes how to access data for elements in a message in the MRM domain.

You can populate an element with data with the SET statement:

SET OutputRoot.MRM.Name = UPPER(InputRoot.MRM.Name);

The field reference on the left hand side of the expression refers to the element called Name within the MRM message domain. This statement takes the input value for the Name field, converts it to uppercase, and assigns the result to the same element in the output message.

The Name element is defined in the noTarget namespace. No namespace prefix is specified in front of the Name part of the field reference in the example above. If you have defined an MRM element in a namespace other than the noTarget namespace, you must also specify a namespace prefix in the statement. For example:

DECLARE brw NAMESPACE 'http://www.ibm.com/Borrowed';

SET OutputRoot.MRM.brw:Borrowed.VideoTitle = 'MRM Greatest Hits';

For more information about using namespaces with messages in the MRM domain, see Accessing the content of a message in the MRM domain with namespace support enabled.
