The function Max() takes an X-path expression as value and returns the largest result of the expression as value.
The Min function serves as a counterpart to this.

Advice The transferred values are interpreted and compared as numerical values.
If this is not possible, the values are compared as a < z (a < A < z < Z).

Max(XPATH-Query)

In this example, we pass all EANs of the Max function within an ORDER.
And get the largest EAN back through the function call.

Max(//SG_25/LIN/DG_C212/@DE_7140)
