Implementing Exact Phrase Replacement

This section covers how to replace specific phrases in your documents with a placeholder text.

Overview:

The ExactPhraseRedaction class allows you to define both the phrase and its replacement, ensuring precise content modification.

Step 1: Define Source and Output Paths Start by specifying paths for your source document and output file:

string sourceFile = "path/to/your/document.docx";
string outputFile = "path/to/redacted_output.docx";

Step 2: Initialize Redactor Create a Redactor instance to manage the redaction process.

using (Redactor redactor = new Redactor(sourceFile))
{
    // Further steps will be implemented here.
}

Step 3: Apply Exact Phrase Redaction Use the ExactPhraseRedaction method, specifying the phrase and its replacement:

redactor.Apply(new ExactPhraseRedaction("John Doe", new ReplacementOptions("[personal]")));

Here, “John Doe” is replaced with “[personal]”. The ReplacementOptions parameter allows customization of how replacements are handled.

Step 4: Save the Redacted Document Finally, save your changes to a specified output path:

var savedFile = redactor.Save(outputFile);
Console.WriteLine($"Document was successfully redacted and saved to {savedFile}.");

Troubleshooting Tips:

  • Ensure file paths are correctly set.
