XMLDOMComparator (OpenJ9 JDK 11)

java.lang.Object
- com.ibm.j9ddr.tools.xml.XMLDOMComparator

```
public class XMLDOMComparator
extends Object
```
Utility class which reads in a configuration properties file which defines a series of XPath statements to execute against two source files. The results are then compared for equivalence. This class is used to check that the output from J9DDR is the same as for JExtract. XPath is used to identify the nodes to compare to allow specific node testing without requiring a complete J9DDR implementation.
