Ponton X/P 2.3 ? Installation and Configuration Guide

For defining subject elements you can use the following element types:
Text – a static text that you enter in the text box.
⇒
⇒
⇒
⇒
Configuration Options
Variable - a predefined variable such as the Message ID, the Message Type or
the Receiver ID/Display Name.
Xpath - the xpath to an element/value contained in the payload message.
Please note that the use of xpath values as notification subject elements may
lead to decreased performance, because the entire payload message has to be
parsed in order to resolve the xpath expression.
Please note as well that only a subset of the complete xpath syntax is supported
for the definition of subject elements. In particular, the following restrictions
apply:
The xpath must be an absolute path starting with the root node of the
payload document.
The xpath must refer to an actual node within the document. In the case of
multiple nodes that satisfy the xpath, the first occurrence will be used.
Reference to node attributes is not possible.
Use of conditional expressions is not possible.
