How to get all inserted and deleted revisions in Word using Java

When the Track Changes feature is enabled in a Word document, all editing actions in the document, such as insertions, deletions, substitutions, and formatting changes, are recorded. Inserted or deleted content can be obtained through the method described in this article.

Introducing Jar

Method 1

Manual introduction: Download Free Spire.Doc for Java locally, unzip it, and find it in the lib folder Spire.Doc.jar file. Open the following interface in IDEA and introduce the jar file in the local path into the Java program:

Method 2

Download through the Maven repository. Configure pom.xml as follows:

<repositories>
<repository>
<id>com.e-iceblue</id>
<url>https://repo.e-iceblue.cn/repository/maven-public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.doc.free</artifactId>
<version>5.2.0</version>
</dependency>
</dependencies>

Get inserted and deleted revisions

• Create a Document instance and use Document .loadFromFile() method loads a sample Word document.

• Create a StringBuilder object, and then use the StringBuilder.append() method to record the data.

• Traverse all Section and every element under the body in the section.

• Use the Paragraph.isInsertRevision() method to determine whether a paragraph is an inserted revision. If so, use the Paragraph.getInsertRevision() method to get the insert revision. Then use the EditRevision.getType() method and the EditRevision.getAuthor() method to get the revision type and author.

• Use the Paragraph.inDeleteRevision() method to determine whether a paragraph is a deleted revision. If so, use the Paragraph.getDeleteRevision() method to get the delete revision. Then use the EditRevision.getType() method and the EditRevision.getAuthor() method to get the revision type and author.

• Traverse all elements in a paragraph to get revisions for a text range.

• Use the FileWriter.write() method to write the contents of StringBuilder to a txt document.
