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. Call the fpInit() function.
  2. Call the fpFilterConfig() function with the following arguments:

    Argument Parameter
    nValue TRUE
    pData NULL

    For example:

    (*fpFilterConfig)(pKVFilter, KVFLT_INCLREVISIONMARK, TRUE, NULL);
  3. Call the fpFilterFile() or fpFilterStream() function.
