Get list of changes Leave feedback
On this page
GroupDocs.Comparison allows you to get list of changes between source and target documents.
To get list of changes, follow these steps:
- Instantiate the Comparer object. Specify the source document path or stream.
- Call the add() method. Specify the target document path or stream.
- Call the compare() method.
- Call the getChanges method.
The following code snippets show how to get list of all changes:
try (Comparer comparer = new Comparer("source.docx")) {
comparer.add("target.docx");
comparer.compare();
ChangeInfo[] changes = comparer.getChanges();
for (ChangeInfo change : changes) {
System.out.println("Change Type: " + change.getType() +
", Page: " + change.getPageInfo().getPageNumber() +
", Change ID: " + change.getId() +
", Text: " + change.getText());
}
}
The result is as follows:
try (final FileInputStream sourceInputStream = new FileInputStream("source.docx");
final Comparer comparer = new Comparer(sourceInputStream);
final FileInputStream targetInputStream = new FileInputStream("target.docx")) {
comparer.add(targetInputStream);
comparer.compare();
ChangeInfo[] changes = comparer.getChanges();
for (ChangeInfo change : changes) {
System.out.println("Change Type: " + change.getType() +
", Page: " + change.getPageInfo().getPageNumber() +
", Change ID: " + change.getId() +
", Text: " + change.getText());
}
}
