XPATH - Select elements by attribute value

[Andreas42]

Hi,

I struggle with choosing unique elements from a list that are given their uniqueness by an attribute.

The XML is the following:

<elemente>
	<element>
		<subelement wert="1"/>
	</element>
	<element>
		<subelement wert="2"/>
	</element>
	<element>
		<subelement wert="3"/>
	</element>
	<element>
		<subelement wert="2"/>
	</element>
	<element>
		<subelement wert="1"/>
	</element>
	<element>
		<subelement wert="4"/>
	</element>
	<element>
		<subelement wert="1"/>
	</element>
</elemente>

The result should be a list of odes like:

<element>
	<subelement wert="1"/>
</element>
<element>
	<subelement wert="2"/>
</element>
<element>
	<subelement wert="3"/>
</element>

Would be great if anybody could help me with that.

Thanks Andreas
