Implementation Guide

Now that you have GroupDocs.Editor set up, let’s explore its features.

Loading a Document

Overview: Loading documents is the first step in editing. This feature allows you to load any document from a specified file path into your .NET application using GroupDocs.Editor.

Steps:

  1. Initialize Editor:

    • Create an instance of the Editor class with the document’s file path.
    string inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
Editor editor;
try
{
    // Load the input document
    editor = new Editor(inputFilePath);
}
catch (Exception ex)
{
    Console.WriteLine("Error loading document: " + ex.Message);
}

Editing a Document

Overview: Once loaded, you can modify the document’s content. This section covers retrieving and editing embedded HTML.

Steps:

  1. Open Document for Editing:

    • Use the Edit method to prepare the document.

  2. Retrieve Content:

    • Extract the document’s HTML content using GetEmbeddedHtml.

  3. Modify Content:

    • Perform text replacements or other edits on the HTML string.
using GroupDocs.Editor;
using GroupDocs.Editor.Options;

Editor editor; // Assume editor is already initialized
EditableDocument beforeEdit = null;
try
{
    // Open the document for editing
    beforeEdit = editor.Edit();
    
    // Retrieve content and resources
    string allEmbeddedInsideString = beforeEdit.GetEmbeddedHtml();
    
    // Modify the embedded HTML content
    string editedContent = allEmbeddedInsideString.Replace("Subtitle", "Edited subtitle");
}
catch (Exception ex)
{
    Console.WriteLine("Error editing document: " + ex.Message);
}
finally
{
    beforeEdit?.Dispose();
}

Saving an Edited Document

Overview: After editing, you may need to save the modified content back into a file. This feature demonstrates saving documents in RTF format.

Steps:

  1. Create EditableDocument:

    • Use FromMarkup with your edited HTML content.

  2. Set Save Options:

    • Choose the desired output format (e.g., RTF).

  3. Save Document:

    • Implement saving logic using the Editor.Save method.
using System;
using System.IO;
using GroupDocs.Editor;
using GroupDocs.Editor.Options;

Editor editor; // Assume editor is already initialized
EditableDocument afterEdit = null;
string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "edited_document.rtf");
try
{
    // Create a new EditableDocument from the edited content
    afterEdit = EditableDocument.FromMarkup(editedContent, null);
    
    // Prepare saving options for RTF format
    WordProcessingSaveOptions saveOptions = new WordProcessingSaveOptions(WordProcessingFormats.Rtf);
    
    // Save the document to a file
    editor.Save(afterEdit, outputPath, saveOptions);
}
catch (Exception ex)
{
    Console.WriteLine("Error saving document: " + ex.Message);
}
finally
{
    afterEdit?.Dispose();
    editor.Dispose();
}
