Chỉnh sửa TXT trong Java

// Load the TXT file into Editor
Editor editor = new Editor("source.txt");

// Create and adjust the TXT edit options
TextEditOptions editOptions = new TextEditOptions();

// Open input TXT document for edit — obtain an intermediate document, that can be edited
EditableDocument beforeEdit = editor.edit(editOptions);

// Grab TXT document content and associated resources from editable document
string content = beforeEdit.getEmbeddedHtml();

// Send the content to WYSIWYG-editor, edit it there, and send edited content back to the server-side
// This step simulates a such operation
string updatedContent = content.replace("text", "Edited text");

// Grab edited content and resources from WYSIWYG-editor and create a new EditableDocument instance from it
EditableDocument afterEdit = EditableDocument.fromMarkup(updatedContent, null);

// Create and adjust the save options
TextSaveOptions saveOptions = new TextSaveOptions();

// Save edited TXT document to the file
editor.save(afterEdit, "edited.txt", saveOptions);
