XMLSession1 |
SESSIONNAME="myXMLSession" |
The name of an existing session in which to associate this activity with. As a safety measure, when a session is created, the XML file bound by that session is saved in memory and the original file is locked. Any modifications by subsequent XML steps are performed on a copy of the XML data saved to memory. Linking several activities to a single session eliminates redundancy. Additionally, a single task supports simultaneous execution of multiple sessions, improving overall efficiency. Use the XML - Output file or XML - Save activity to output the in-memory representation of the XML session to a file or variable. To end the session, use the XML - End session activity. |
