Customising the XML formatter in Eclipse?

How do I customise the XM开发者_StackOverflow社区L formatter in Eclipse? I've looked inside the preferences menu in the XML node but can't find it there. Am I just missing it or is it hidden elsewhere?

Thanks

Type format in the quick search field above the TreeView in the eclipse preferences and the preferences will be reduced to show only format preferences. You find then easily

XML -> XML Files -> Editor

Here you can configure some few settings.
