The <oXygen/> XML Grid Editor allows the repetitive XML content to be edited in a table-like fashion, similar to a spreadsheet application. There are available operations for row and column addition/deletion and table sorting. You can organize your XML documents by moving nodes around using drag and drop.
The XML Grid Editor is synchronized with the text editor, so you can switch between them with no need for saving the edited document.
