Many people wrote me an email that the word-wrap unfortunately isn't working for the XML editor. The new version now supports XML editors and can be downloaded via update site or manually from the word-wrap development website. Credit is due to Tamás Szekeres who provided a great idea on how to enable the plugin for XML editors. Thank you very much!
The update is developed for Eclipse version 4.3 Kepler but it's also working with 4.2 Juno. By the way: The source code of the word-wrap plugin is now also available on Github.
I'm curious which version of Eclipse you are using. Feel free to leave a comment in the blog or to send me an email. This way I get an overview for which versions my plugins are used or going to be requested.
