DocBook looks like a really great format for any kind of documentation.
Until you try to read it 😐
Do you know any working online-reader or standalone software (smaller than 500MB, please) to read/preview a DocBook XML file without having to export/save it to another specific format?
HTML preview would be enough.

You can use XMLMind XML Editor - Java-based GUI desktop editor - for purpose of view/evaluate your DocBook/XML content. Of course, you can also edit it within this editor in case you need it.
You can use editor for free for individual | non-commercial | evaluating purpose. If you need commercial day-by-day work with DocBook/XML files - the type of license is fully depend on type of using this editor. See complete license types list.
Pitfalls:
Despite XMLMind XML Editor (XXE for short) is a quite complex editor, some features of DocBook/XML standard, due to its nature, can only be fully discovered after processing source files into target formats (i.e.: profiling by multiple bases, highly customized TOCs, complex pagination using XSL:FO, etc.)
Editing in this editor require some time to get familiar with its editing concepts. Due to it is a fully WYSIWYM editor - its editing behavior is quite different from the ordinary WYSIWYG wordprocessing-like editors (MS Word, LibreOffice, Abiword, OpenOffice, etc)
