I apply html HTML page to edit and send xml on the server. To make it more useful I would like to have HTML based decision with following properties:

1. Highlight XML syntax during editing (required);
2. Lightweight in size (e.g. 5+ Mb is too much) (required)
3. Validate XML on-the-fly or by request (e.g. by button press) (optional)
4. Be free (is pretty required, but I'm open for paid decision if it really covers all requirements);

Thanks for any suggestions!

You may wish to check out CodeMirror, which has XML syntax highlighting, autoplete, tag closing, and some other great features.

I'm not certain that CodeMirror includes XML validation per se, but it shouldn't be very difficult to add if you can just use an XmlHttpRequest to send the content to an online XML validation service of some sort.
