Implementation Guide

Creating an EditableDocument Instance

Overview: Load and edit documents by creating an EditableDocument instance.

Loading a Document

using GroupDocs.Editor.Options;

// Load your document with appropriate options
Editor editor = new Editor(inputFilePath, new WordProcessingLoadOptions());

// Create EditableDocument from the loaded file
EditableDocument beforeEdit = editor.Edit(new WordProcessingEditOptions());

Generating Embedded HTML from EditableDocument

Overview: Convert an entire document to a single embedded HTML string with stylesheets and resources.

using System.Collections.Generic;
using GroupDocs.Editor.HtmlCss.Resources;

// Generate embedded HTML
string allAsHtmlInsideOneString = beforeEdit.GetEmbeddedHtml();

Extracting Resources from EditableDocument

Overview: Retrieve images, fonts, CSS, and other resources from your document.

List<IImageResource> allImages = beforeEdit.Images;
List<FontResourceBase> allFonts = beforeEdit.Fonts;
List<CssText> allStylesheets = beforeEdit.Css;
List<IHtmlResource> allResources = beforeEdit.AllResources;

Obtaining HTML Content from EditableDocument

Overview: Extract pure HTML content without embedded resources.

string htmlMarkup = beforeEdit.GetContent();

Adjusting External Links in HTML Content

Overview: Modify external links for images, CSS, and fonts using custom prefixes.

using System.Collections.Generic;

// Define custom handlers for resource URLs
string customImagesRequesthandlerUri = "http://example.com/ImagesHandler/id=";
string customCssRequesthandlerUri = "http://example.com/CssHandler/id=";

// Adjust HTML content with prefixed links
string prefixedHtmlMarkup = beforeEdit.GetContent(customImagesRequesthandlerUri, customCssRequesthandlerUri);

Saving EditableDocument as HTML File

Overview: Save the edited document back to disk in HTML format.

using System.IO;

string htmlFilePath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "document.html"); // Adjust the output path
beforeEdit.Save(htmlFilePath);

Disposing and Event Handling for EditableDocument

Overview: Manage resource disposal and handle events related to document lifecycle.

Console.WriteLine("beforeEdit variable of EditableDocument type is {0} disposed", !beforeEdit.IsDisposed ? "not" : "already");

// Subscribe to the disposing event
EventHandler someMethod = delegate {
    Console.WriteLine("Disposing event was spotted!");
};
beforeEdit.Disposed += someMethod;

Creating EditableDocument from HTML Content

Overview: Reconstruct an EditableDocument instance from existing HTML content.

EditableDocument afterEditFromFile = EditableDocument.FromFile(htmlFilePath, null);
EditableDocument afterEditFromMarkup = EditableDocument.FromMarkup(htmlMarkup, allResources);

// Dispose resources once done
beforeEdit.Dispose();
afterEditFromFile.Dispose();
afterEditFromMarkup.Dispose();
editor.Dispose();
