Recursive?

Hi everybody,

my xml:
<?xml version="1.0" encoding="ISO-8859-15"?>
<it>
	<tt id="20">
		<numbering>1</numbering>
		<name><![CDATA[test0]]></name>
		<tc id="4611686020000000015">
			<numbering>1.1</numbering>
			<name><![CDATA[test1]]></name>
		</tc>
	</tt>
	<tt id="21">
		<numbering>2</numbering>
		<name><![CDATA[test2]]></name>
		<tt id="22">
			<numbering>2.1</numbering>
			<name><![CDATA[test3]]></name>
			<tt id="23">
				<numbering>2.1.1</numbering>
				<name><![CDATA[tgf]]></name>
				<tc id="4611686020000000012">
					<numbering>2.1.1.1</numbering>
					<name><![CDATA[test4]]></name>
				</tc>
				<tc id="4611686020000000013">
					<numbering>2.1.1.2</numbering>
					<name><![CDATA[test5]]></name>
				</tc>
			</tt>
			<tc id="4611686020000000014">
				<numbering>2.1.2</numbering>
				<name><![CDATA[test6]]></name>
			</tc>
		</tt>
	</tt>
</it>

I want to get this:

number name

1 test0
  1.1 test1
2 test2
  2.1 test3
    2.1.1 test4
      2.1.1.1 test5
      2.1.1.2 test6
    2.1.2 test7


Should i do it recursively or is there a better way to achieve it?

Thanks and best regards.

Sven
