Problem with empty spaces

Hi List,

In my XSLT, I converted some of the child nodes vales as attributes to the
parent. In the resultant XML file, I am getting empty spaces in place
of child nodes which are not added. How can I eliminate the white space.
for eg:
input xml looks like this:
<A>
	<ch name="ch1" value="1"/>
	<ch name="ch2" value="2"/>
	<ch name="ch3" value="3"/>
	<B>
		<ch name="ch4" value="4"/>
		<ch name="ch5" value="5"/>
	</B>
</A>

Output XML looks like this:
<A ch1="1" ch2="2" ch3="3">



	<B ch4="4" ch5="5" />
</A>

Thanks,
Laxmi Narayana
