Combining XML documents

[vt123]

I am trying to merge 2 xml files in to one. They simply need to one another. Any help would be appreciated.

File 1:
<?xml version="1.0" encoding="ISO-8859-1"?> 
<catalog>
	<data>
		<title>Title1</title>
		<description>Description1</description>
	</data>
	<data>
		<title>Title2</title>
		<description>Description2</description>
	</data>
</catalog>


File 2:
<?xml version="1.0" encoding="ISO-8859-1"?> 
<catalog>
	<data>
		<title>Title3</title>
		<description>Description1</description>
	</data>
	<data>
		<title>Title4</title>
		<description>Description2</description>
	</data>
</catalog>


Expected result:
<?xml version="1.0" encoding="ISO-8859-1"?> 
<catalog>
	<data>
		<title>Title1</title>
		<description>Description1</description>
	</data>
	<data>
		<title>Title2</title>
		<description>Description2</description>
	</data>
	<data>
		<title>Title3</title>
		<description>Description1</description>
	</data>
	<data>
		<title>Title4</title>
		<description>Description2</description>
	</data>
</catalog>
