Basic initialization

Editor is GroupDocs.Editor’s main class that loads and manages document content. XmlEditOptions defines how the XML is presented for editing.

import com.groupdocs.editor.Editor;

String inputFilePath = "path/to/your/sample.xml";
Editor editor = new Editor(inputFilePath);

Implementation guide

In this section we’ll walk through the core steps for load XML Java, edit the document, convert XML TXT, and extract XML metadata.

Loading and editing an XML file

The Editor class is the core component that loads and manages XML documents.
The EditableDocument provides methods to modify the markup of a loaded XML document.

Direct answer: Load the XML with new Editor("input.xml", new XmlEditOptions()), apply any XmlHighlightOptions you need, modify the markup through EditableDocument, and finally call editor.save()—all in three concise lines of code.

Step 1: load the XML document

Editor loads the file and creates an in‑memory representation ready for editing.

import com.groupdocs.editor.Editor;
import com.groupdocs.editor.editable.EditableDocument;
import com.groupdocs.editor.options.XmlEditOptions;

String inputFilePath = "YOUR_DOCUMENT_DIRECTORY" + "/sample.xml";
Editor editor = new Editor(inputFilePath);

Step 2: configure edit options

XmlEditOptions lets you turn on syntax highlighting, line numbers, and custom fonts.

XmlEditOptions editOptions = new XmlEditOptions();
editOptions.setAttributeValuesQuoteType(QuoteType.DoubleQuote); // Use double quotes for attribute values
EditableDocument beforeEdit = editor.edit(editOptions);

Step 3: modify content

EditableDocument provides replace, insert, and remove methods that work on raw markup strings.

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

TextSaveOptions specifies how the document is saved as plain text, including encoding and formatting options.

Direct answer: Use WordProcessingSaveOptions to export to DOCX or TextSaveOptions for plain‑text output; simply pass the options to editor.save("output.docx", saveOptions) or editor.save("output.txt", saveOptions).

Step 1: save as DOCX

WordProcessingSaveOptions preserves layout while converting XML structures into Word tables and headings.

import com.groupdocs.editor.options.WordProcessingSaveOptions;
import java.nio.charset.StandardCharsets;

String outputWordPath = "YOUR_OUTPUT_DIRECTORY" + "/output.docx";
WordProcessingSaveOptions wordSaveOptions = new WordProcessingSaveOptions(WordProcessingFormats.Docx);
afterEdit.save(outputWordPath, wordSaveOptions);

Step 2: save as TXT

TextSaveOptions writes a clean, indented text version of the XML, respecting the formatting rules you set.

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

XmlHighlightOptions lets you customize colors and fonts for XML tags, attributes, and values during editing.

Direct answer: Create an XmlHighlightOptions instance, set font families, sizes, and colors for tags, attributes, and CDATA, then assign it to XmlEditOptions before loading the document.

import com.groupdocs.editor.options.XmlHighlightOptions;
import com.groupdocs.editor.htmlcss.css.datatypes.ArgbColors;
import com.groupdocs.editor.htmlcss.css.properties.FontSize;
import com.groupdocs.editor.htmlcss.css.properties.FontStyle;
import com.groupdocs.editor.htmlcss.css.properties.FontWeight;
import com.groupdocs.editor.htmlcss.css.properties.TextDecorationLineType;

XmlEditOptions editOptions = new XmlEditOptions();
XmlHighlightOptions highlightOptions = editOptions.getHighlightOptions();

highlightOptions.getXmlTagsFontSettings().setSize(FontSize.Large);
highlightOptions.getXmlTagsFontSettings().setColor(ArgbColors.Olive);

highlightOptions.getAttributeNamesFontSettings().setName("Arial");
highlightOptions.getAttributeNamesFontSettings().setLine(TextDecorationLineType.Underline);

highlightOptions.getAttributeValuesFontSettings().setStyle(FontStyle.Italic);

highlightOptions.getCDataFontSettings().setLine(TextDecorationLineType.LineThrough);

highlightOptions.getHtmlCommentsFontSettings().setColor(ArgbColors.Lightgreen);

highlightOptions.resetToDefault();
afterEdit.dispose();
editor.dispose();

Format options for XML editing

XmlFormatOptions controls indentation, line‑break style, and element collapsing when saving XML.

Direct answer: XmlFormatOptions controls indentation (tabs vs. spaces), line‑break style, and whether empty elements are collapsed, giving you full control over the final appearance.

import com.groupdocs.editor.htmlcss.css.datatypes.Length;
import com.groupdocs.editor.htmlcss.css.datatypes.LengthUnit;

XmlEditOptions editOptions = new XmlEditOptions();
XmlFormatOptions formatOptions = editOptions.getFormatOptions();

formatOptions.setEachAttributeFromNewline(true);
formatOptions.setLeftIndent(Length.fromValueWithUnit(20, LengthUnit.Px));
formatOptions.setLeafTextNodesOnNewline(true);
formatOptions.setLeftIndent(Length.UnitlessZero);

afterEdit.dispose();
editor.dispose();

Retrieve XML metadata information

TextualDocumentInfo holds extracted information about a document, including XML‑specific metadata.

Direct answer: Call editor.getDocumentInfo(null) to obtain a TextualDocumentInfo object; its xmlInfo property contains documentType, encoding, and rootElementName without parsing the whole file.

import com.groupdocs.editor.IDocumentInfo;
import com.groupdocs.editor.metadata.TextualDocumentInfo;

Editor editor = new Editor(inputFilePath);
IDocumentInfo info = editor.getDocumentInfo(null);
TextualDocumentInfo xmlInfo = (TextualDocumentInfo)info;

afterEdit.dispose();
editor.dispose();

How to load XML Java – common pitfalls

Loading XML with GroupDocs.Editor is straightforward, but you must ensure the file path is correct, the appropriate license is applied, and the document encoding matches the source. Using absolute paths or Paths.get(...) avoids resolution errors, a valid license prevents trial watermarks, and setting the correct charset in XmlEditOptions guarantees proper character handling.

  • Incorrect file path – always resolve paths with Paths.get(...) or use an absolute path.
  • Missing license – without a valid license the editor runs in trial mode and adds watermarks to the output.
  • Encoding mismatches – ensure the source XML is UTF‑8 or explicitly set the expected encoding in XmlEditOptions.

How to convert XML TXT using GroupDocs.Editor

Converting an edited XML document to plain text with GroupDocs.Editor is done via the TextSaveOptions class. Configure the options to preserve indentation, line breaks, and character encoding, then call editor.save("output.txt", saveOptions). This produces a clean, human‑readable TXT file that reflects the original XML structure while removing markup tags.

XML manipulation java – advanced tips

  • Batch replace – leverage String.replaceAll with regular expressions for large‑scale transformations.
  • Preserve comments – the editor retains XML comments unless you delete them explicitly.
  • Reuse resources – EditableDocument.fromMarkup recreates the document while keeping embedded resources (images, styles) intact.

How to extract XML metadata

Extracting metadata from an XML file is simple with GroupDocs.Editor. After loading the document, invoke editor.getDocumentInfo(null) to obtain a TextualDocumentInfo object, which contains an xmlInfo section. This provides details such as the document type, encoding, and root element name without requiring full DOM parsing.

  • xmlInfo.getDocumentType() – returns “XML”.
  • xmlInfo.getEncoding() – the character encoding (e.g., UTF‑8).
  • xmlInfo.getRootElementName() – the name of the root element, giving you a quick overview of the document structure.

Practical applications

Real‑world scenarios where these techniques shine:

  1. Content management systems – automatically update XML‑based configuration files across environments.
  2. E‑commerce platforms – keep product catalogs synchronized by editing XML feeds on the fly.
  3. Data interchange – turn legacy XML reports into human‑readable TXT or DOCX for non‑technical stakeholders.
