Implementation Guide

In this section, we’ll break down the process of creating and editing editable documents into manageable features. Each feature will be explained with code snippets and detailed explanations.

Creating and Editing Editable Documents

Overview

Loading a document as an EditableDocument is your first step toward making any modifications.

import com.groupdocs.editor.Editor;
import com.groupdocs.editor.EditableDocument;

// Load the document into an EditableDocument
Editor editor = new Editor("YOUR_DOCUMENT_DIRECTORY/sample.docx");
EditableDocument beforeEdit = editor.edit();

Explanation

  • Editor: This class is responsible for loading and managing documents.
  • EditableDocument: Represents a loaded document that can be edited.

Extracting Document Resources

Overview

You can extract various resources such as images, fonts, and stylesheets from an EditableDocument.

import com.groupdocs.editor.htmlcss.resources.IHtmlResource;
import java.util.List;

// Extract embedded HTML, images, fonts, and CSS
String allAsHtmlInsideOneString = beforeEdit.getEmbeddedHtml();
List<IHtmlResource> allResources = beforeEdit.getAllResources();

// Accessing specific resources
List<String> stylesheets = beforeEdit.getCssContent();

Explanation

  • getEmbeddedHtml(): Retrieves the document’s HTML content.
  • getAllResources(): Lists all embedded resources in the document.

Overview

Modify external links within your document’s HTML markup to suit your needs.

String customImagesRequesthandlerUri = "http://example.com/ImagesHandler/id=";
String htmlMarkup = beforeEdit.getContentString(customImagesRequesthandlerUri);

Explanation

  • getContentString(): Adjusts the content string with custom URIs for resources.

Saving Editable Document to Disk

Overview

Once edits are complete, save your EditableDocument back to disk as an HTML file.

// Save the edited document as an HTML file
beforeEdit.save("YOUR_OUTPUT_DIRECTORY/output.html");

Explanation

  • save(): Writes the modified content back to a specified path.

Checking Disposal State of EditableDocument

Overview

Ensure that resources are properly disposed of by checking the disposal state.

String res = !beforeEdit.isDisposed() ? "not" : "already";

Explanation

  • isDisposed(): Checks whether the document has been disposed of, ensuring resource management.

Creating EditableDocument from HTML

Overview

Create an EditableDocument instance from existing HTML content or files.

import com.groupdocs.editor.EditableDocument;

// Create EditableDocument from file and markup
EditableDocument afterEditFromFile = EditableDocument.fromFile("YOUR_OUTPUT_DIRECTORY/output.html");
EditableDocument afterEditFromMarkup = EditableDocument.fromMarkup(htmlMarkup, allResources);

Explanation

  • fromFile(): Loads an EditableDocument from a specified HTML file.
  • fromMarkup(): Creates an EditableDocument from raw HTML and resources.

Practical Applications

GroupDocs.Editor Java offers numerous real-world applications:

  1. Content Management Systems (CMS): Integrate document editing capabilities into your CMS for seamless content updates.
  2. Collaborative Editing Platforms: Enable multiple users to edit documents simultaneously with version control.
