Summary

This Repo deals with the following problem: Examining the resemblance of an XML-File and its corresponding Java-Object counterpart, based on their struture and data.

This problem is solved using the following strategies:

• Design a data structure for representing an abstract tree.
• Develop a JavaObject-to-Tree Parser and an XML-to-Tree parser.
• Develop a Comparator to compare the trees resulting from our parsers.

Usage

XML to ObjectElement:

Parse your XML-File using the DomXmlParser.

ObjectElement xmlElement;
try {
    DomXmlParser domXmlParser = new DomXmlParser("yourXMLFile.xml");
    xmlElement = domXmlParser.getParseResult();
} catch (ParserConfigurationException | SAXException | IOException) {
    ...
}

Java Object to ObjectElement:

Parse a Java Object using the JavaObjectParser.

JavaObjectParser javaObjectParser = new JavaObjectParser();
ObjectElement javaElement;
try {
    javaElement = javaObjectParser.getObjectElement(yourObject);
} catch (IllegalArgumentException | IllegalAccessException ex) {
    ...
}

Compare both results:

Use the Comparator to compare trees resulting from same data structures:

Comparator comparator = new Comparator();
boolean result = comparator.compare(element1, element2);

Use the Comparator extension JavaXmlComparator to compare a tree resulting from a Java Object with a tree from Xml:

Comparator comparator = new JavaXmlComparator();
boolean result = comparator.compare(javaElement, xmlElement);
