Apache Camel Splitter doesn't split correctly xml file

I have a big xml file and wanted to split it in small individual files with the Apache Camel Splitter. Therefore I used the code of the example:

<route>
<from uri="file:inbox"/>
<split streaming="true>
<tokenize token="order" xml="true"/>
<to uri="activemq:queue:order"/>
</split>
</route>

my xml file looks so:

<orders>
<order>
<Parameter Name="CustomerID" Value="701423"/>
</order>
<order>
<Parameter Name="CustomerID" Value="7011337"/>
</order>
<order>
<Parameter Name="CustomerID" Value="701789"/>
</order>
</orders>

At the end my splitted message looks like the followings:

<order>
<Parameter Name="CustomerID" Value="701789"/>
</order>

I've just only one file with the last order of the big xml file instead of many small xml files. Could you tell me what is wrong? Thank you so much!
