Extract Deleted Text Marked by Tracked Changes

The revision tracking feature in applications—such as Microsoft Word’s Track Changes—marks changes to a document (typically, strikethrough for deleted text and underline for inserted text) and tracks each change by reviewer name and date.

If revision tracking was enabled when text was deleted from a source document, you can configure Filter to extract the deleted text. Filter does not extract the reviewer name and revision date.

To extract deleted text from a document and include it in the filtered output

  1. Create a Session object.

  2. Enable revision tracking by calling revision_marks(true) on the Configuration object.

  3. Call filter() on the Session object.

See The Session Class for more information.
