[xsl] Sorting & Grouping

[Satish Patil <Satish.Patil@xxxxxxx>]

Hi All,

I need help in sorting & grouping.

I have a XML 
<parent>
	<child>
		<name>AAAA</name>
		<emp_id>1</emp_id>
	</child>
	<child>
		<name>BBBBB</name>
		<emp_id>3</emp_id>
	</child>
	<child>
		<name>CCCC</name>
		<emp_id>2</emp_id>
	</child>
	<child>
		<name>DDDDD</name>
		<emp_id>2</emp_id>
	</child>
</parent>

How to  write an XSL that sorts & groups according to <emp_id>. The intended
O/P is

1 AAAA
2 CCCC
  DDDD
3 BBBB

Thank you in advance.
