XML is a convenient toolkit for web, e-commerce, and cross-platform portable applications.

In this article, we discuss some XML editors that will boost your efficiency with XML.

What is XML?

In XML, you can store your data and render the content for different devices. Many markup languages follow XML’s syntax with their own semantics, for example, HTML.

XML is used in web applications like Shopify when creating a product feed. Product feeds are the information about your store’s products, usually in XML format. XML files are sent to different merchants like Amazon and Google Shopping to synchronize with the platforms.

Since XML is essential in developing applications, most modern frameworks utilize XML for the data feed. When you have a large XML file, you need to edit it and perform calculations with it. XML Editors are the specialized tools for editing your XML files using DTD and different structures like schemas and trees.

In this article, you’ll find free, open-source, and premium license XML Editors.


Oxygen XML is a cross-platform editor developed in Java. It offers several features for editing XML documents like:

  • Checking for proper XML form.
  • Validating against schemas like DTD, W3C XML Schema, RELAX NG, Schematron, NRL, and NVDL schemas.

Oxygen XML offers mainly three views designed for editing XML documents.

  • Text view: Text view is the default view for editing an XML document.
  • Grid view: Grid view formats your XML document in a spreadsheet-like style. In this view, the left-most column shows the elements, along with comments and processing instructions, at the root level, and the next column shows attributes of root elements and every unique first child of the root XML element.
  • Author view: It provides a WYSIWYM(What You See is What You Mean) view for the XML. While editing in this view, the XML elements are human-friendly while still maintaining XML’s nesting and semantics.

Emacs for XML
