Comparing Documents in Aspose.Words for Java

Introduction to Document Comparison

Document comparison involves analyzing two documents and identifying differences, which can be essential in various scenarios, such as legal, regulatory, or content management. Aspose.Words for Java simplifies this process, making it accessible to Java developers.

Setting Up Your Environment

Before we dive into document comparison, ensure you have Aspose.Words for Java installed. You can download the library from the Aspose.Words for Java releases page. Once downloaded, include it in your Java project.

Basic Document Comparison

Let’s start with the basics of document comparison. We’ll use two documents, docA and docB, and compare them.

Document docA = new Document("Your Directory Path" + "Document.docx");
Document docB = docA.deepClone();
docA.compare(docB, "user", new Date());
System.out.println(docA.getRevisions().getCount() == 0 ? "Documents are equal" : "Documents are not equal");

In this code snippet, we load two documents, docA and docB, and then use the compare method to compare them. We specify the author as “user,” and the comparison is performed. Finally, we check if there are revisions, indicating differences between the documents.

Customizing Comparison with Options

Aspose.Words for Java provides extensive options for customizing document comparison. Let’s explore some of them.

Ignore Formatting

To ignore differences in formatting, use the setIgnoreFormatting option.

CompareOptions options = new CompareOptions();
options.setIgnoreFormatting(true);
docA.compare(docB, "user", new Date(), options);

Ignore Headers and Footers

To exclude headers and footers from comparison, set the setIgnoreHeadersAndFooters option.

CompareOptions options = new CompareOptions();
options.setIgnoreHeadersAndFooters(true);
docA.compare(docB, "user", new Date(), options);

Ignore Specific Elements

You can selectively ignore various elements like tables, fields, comments, textboxes, and more using specific options.

CompareOptions options = new CompareOptions();
options.setIgnoreTables(true);
options.setIgnoreFields(true);
options.setIgnoreComments(true);
options.setIgnoreTextboxes(true);
docA.compare(docB, "user", new Date(), options);

Comparison Target

In some cases, you may want to specify a target for the comparison, similar to Microsoft Word’s “Show changes in” option.

CompareOptions options = new CompareOptions();
options.setIgnoreFormatting(true);
options.setTarget(ComparisonTargetType.NEW);
docA.compare(docB, "user", new Date(), options);

Granularity of Comparison

You can control the granularity of comparison, from character-level to word-level.

DocumentBuilder builderA = new DocumentBuilder(new Document());
DocumentBuilder builderB = new DocumentBuilder(new Document());
builderA.writeln("This is A simple word");
builderB.writeln("This is B simple words");
CompareOptions compareOptions = new CompareOptions();
compareOptions.setGranularity(Granularity.CHAR_LEVEL);
builderA.getDocument().compare(builderB.getDocument(), "author", new Date(), compareOptions);

Conclusion

Comparing documents in Aspose.Words for Java is a powerful capability that can be employed in various document processing scenarios. With extensive customization options, you can tailor the comparison process to your specific needs, making it a valuable tool in your Java development toolkit.
