Migration Notes Leave feedback
On this page
Here are the key reasons to use the new updated API provided by GroupDocs.Editor for Java since version 20.8:
- Editor class introduced as a single entry point to manage the document editing process to any supported file format (instead of EditorHander class from previous versions).
- Product architecture was redesigned from scratch in order to decreased memory usage (from 10% to 400% approx. depending on document type).
- Document editing and saving options simplified so it’s easy to instantiate proper options class and control over document editing and saving processes.
Here is a brief comparison of how to edit document in HTML form using old and new API.
Old coding style
InputStream sourceStream = new FileInputStream("C:\\sample.docx");
try {
InputHtmlDocument htmlDoc = EditorHandler.toHtml(sourceStream);
// Obtain HTML document content
String htmlContent = htmlDoc.getContent();
// Edit html in WYSIWYG-editor...
// ...
// Save edited html to original document format
OutputHtmlDocument editedHtmlDoc = OutputHtmlDocument.fromMarkup(htmlContent, CommonUtilities.sourcePath + CommonUtilities.sourceResourcesFolder);
WordsSaveOptions saveOptions = new WordsSaveOptions();
saveOptions.setOutputFormat(WordFormats.Rtf);
OutputStream outputStream = new FileOutputStream("C:\\output\\edited.docx");
EditorHandler.toDocument(editedHtmlDoc, outputStream, saveOptions);
outputStream.close();
} catch (Exception ex){
ex.getMessage();
}
// close stream object to release file for other methods.
inputStream.close();
New coding style
String documentPath = "C://sample.docx";
try {
Editor editor = new Editor(documentPath);
// Obtain editable document from original DOCX document
EditableDocument editableDocument = editor.edit();
String htmlContent = editableDocument.getEmbeddedHtml();
// Pass htmlContent to WYSIWYG editor and edit there...
// ...
// Save edited EditableDocument object to some WordProcessing format - DOC for example
WordProcessingSaveOptions saveOptions = new WordProcessingSaveOptions(WordProcessingFormats.Docx);
editor.save(editableDocument, "C:\\output\\edited.docx", saveOptions);
} catch (Exception ex) {
ex.getMessage();
}
