Table-XML-Editor is a project mainly written in PHP and JAVASCRIPT, it's free.
Edit simple XML files in HTML
This project is a demonstration of using the "contenteditable" attribute to edit an XML file in a web browser.
When index.php is loaded, it reads an XML file ('data.xml' is included as an example) and converts it to an HTML table.
The cells of the table are made editable using the contenteditable attribute.
When the HTML table is saved, it is converted back to XML and saved to the original file ('data.xml').
