For details, refer to Logic specifications (Document Mapper/Variable Mapper).

Properties

Category	Property	Description
Required settings	XPath expression	Specify the position to get the value by XPath expression.
Comment	Comment	You can write a description of the logic. It doesn't affect the conversion process.

Specification limits

This logic can't be used in Document Mapper with table model type of input/output data.

Notes

The input handler can only be mapped from the input source element because it specifies the element serving as the processing criteria. It can't be mapped from an attribute, a script variable or a Mapper logic and such.
Specify a relative path for XPath expression in case of getting the value associated with the currently processing node in the loop process.
When an absolute path is specified in XPath expression, the logic gets a value not from the element specified with the input handler, but from the root element.
