String inputFilePath = "YOUR_DOCUMENT_DIRECTORY" + "/sample.xml";
Editor editor = new Editor(inputFilePath);
2. Configure Edit Options
XmlEditOptions editOptions = new XmlEditOptions();
editOptions.setAttributeValuesQuoteType(QuoteType.DoubleQuote); // Use double quotes for attribute values
EditableDocument beforeEdit = editor.edit(editOptions);
3. Modify Content
String originalTextContent = beforeEdit.getContent();
String updatedTextContent = originalTextContent.replace("John", "Samuel");
EditableDocument afterEdit = EditableDocument.fromMarkup(updatedTextContent, beforeEdit.getAllResources());
afterEdit.dispose();
editor.dispose();

Saving Edited XML Content to Different Formats

Overview: This feature demonstrates how to save your edited XML content into formats such as Word (DOCX) and Text (TXT).

Step-by-Step Implementation:

1. Save as DOCX

WordProcessingSaveOptions wordSaveOptions = new WordProcessingSaveOptions(WordProcessingFormats.Docx);
afterEdit.save(outputWordPath, wordSaveOptions);
2. Save as TXT
import com.groupdocs.editor.options.TextSaveOptions;

String outputTxtPath = "YOUR_OUTPUT_DIRECTORY" + "/output.txt";
TextSaveOptions txtSaveOptions = new TextSaveOptions();
txtSaveOptions.setEncoding(StandardCharsets.UTF_8);
afterEdit.save(outputTxtPath, txtSaveOptions);

Highlight Options for XML Editing
