Class PlaceholderDifferenceEvaluator

java.lang.Object
org.xmlunit.placeholder.PlaceholderDifferenceEvaluator
All Implemented Interfaces:
DifferenceEvaluator
public class PlaceholderDifferenceEvaluator extends Object implements DifferenceEvaluator
This class is used to add placeholder feature to XML comparison.

This class and the whole module are considered experimental and any API may change between releases of XMLUnit.

To use it, just add it with DiffBuilder like below

 Diff diff = DiffBuilder.compare(control).withTest(test).withDifferenceEvaluator(new PlaceholderDifferenceEvaluator()).build();

Supported scenarios are demonstrated in the unit tests (PlaceholderDifferenceEvaluatorTest).

Default delimiters for placeholder are ${ and }. Arguments to placeholders are by default enclosed in ( and ) and separated by , - whitespace is significant, arguments are not quoted.

To use custom delimiters (in regular expression), create instance with the PlaceholderDifferenceEvaluator(String, String) or PlaceholderDifferenceEvaluator(String, String, String, String, String) constructors.
