An XML editor is a markup language editor with added functionality to facilitate the editing of XML. This can be done using a plain text editor, with all the code visible, but XML editors have added facilities like tag completion and menus and buttons for tasks that are common in XML editing, based on data supplied with document type definition (DTD) or the XML tree.

There are also graphical XML editors that hide the code in the background and present the content to the user in a more user-friendly format, approximating the rendered version or editing forms. This is helpful for situations where people who are not fluent in XML code need to enter information in XML based documents such as time sheets and expenditure reports. And even if the user is familiar with XML, use of such editors, which take care of syntax details, is often faster and more convenient.
