replace >< with > newline <

Hi All,
I have the command in PERL for performing this, but Can you please suggest me how can i perform this using AWK:

My input xml file looks like this:

<aaa>hello</aaa><bbb>hai</bbb>

I want the output like this ( means need new line after end of each xml tag):

<aaa>hello</aaa>
<bbb>hai</bbb>

Thanks in Advance,

# echo "<aaa>hello</aaa><bbb>hai</bbb>" | awk 'gsub("><",">\n<")'
<aaa>hello</aaa>
<bbb>hai</bbb>
#
