[xml] How to output formated xml document?

[Zhonghua Ke <kcynice hotmail com>]

For example, i want to output a xml document looks like:
<root>
     <node1>node1 value</node1>
     <node2>node2 value</node2>
     ......
</root>

other than:
<root><node1>node1 value</node1><node2>node2 value</node2>......</root>

I have tried the "xmllint" example by using "--format" argument, but it doesn't work.
Any ideas?
