Empty multivalue ref field from views feed

Hi, thanks for the very useful module. Im using Views Data Export module to generate a XML page with content from one site and then using Feeds Xpath Parser on another site to import the content. Everything works perfectly with the exception of multivalue entity reference fields in my XML feed. When I debug the context the only thing returned is the trailing tag form the field. Heres an example of my XML which all seems perfectly valid so I cant workout why XPath Parser would be having trouble reading it.

<?xml version="1.0" encoding="UTF-8" ?>
<nodes>
  <node>
      <nodetitle>MY NODE TITLE</nodetitle>
        <uuid>0f84fa17-21b0-18a4-851b-43182c4f65f1</uuid>
        <standards>WRSTC</standards>
    </node>
  <node>
      <nodetitle>ANOTHER NODE TITLE</nodetitle>
        <uuid>163151ca-54dc-6524-bdcg-25e258bf352a</uuid>
        <standards>
          <item>ISO</item>
          <item>WRSTC</item>
        </standards>
    </node>
</nodes>

And the context I get in the Feeds Xpath Parser is...

<node> <nodetitle>MY NODE TITLE</nodetitle> <uuid>0f84fa17-21b0-18a4-851b-43182c4f65f1</uuid> <standards/> </node>
<node> <nodetitle>ANOTHER NODE TITLE</nodetitle> <uuid>163151ca-54dc-6524-bdcg-25e258bf352a</uuid> <standards/> </node>

Im not really sure where this error is coming from, but as far as I can see my output XML seems perfectly valid so I dont understand why my context is missing elements. Has anyone else had similar issues like this or got any suggestions why this might be happening.

Thanks
