Functionality Beyond Syntax Highlighting
An XML editor goes beyond the syntax highlighting offered by many plaintext editors and generic source code editors, verifying the XML source based on an XML schema or XML DTD, and some can do it as the document is being edited in real time. Other features of an editor designed specifically for editing XML might include element word completion and automatic appending of a closing tag whenever an opening tag is entered. These features can help to prevent typographically originating errors in the XML code. Some XML editors provide for the ability to run an XSLT transform, or series of transforms, over a document. Some of the larger XML packages even offer XSLT debugging features and XSL-FO processors for generation of PDF files from documents.
