The example process (see
Example XPath expressions
) dictates that purchases of a total cost
less than $300 do not require a manager’s approval. Those purchases can
be routed to an administrator for immediate ordering. A route condition decides
whether to route the purchases to an administrator or a manager.
The condition uses an expression to access the value of the
totalCost
field
on the form.
The process data tree is illustrated in the following diagram.
The following expression retrieves the value of the
totalCost
field
on the form:
/process_data/purchaseForm/object/data/xdp/datasets/data/purchaseOrder/cost/totalCost
Note:
When extracting the date from a form field and
processing it using a Date or Date-Time function in an XPath expression,
the extracted date must be in the format that is valid for the function.
(See
Date and time parameters
.)
