XML Parsing in liquid

My Xml looks like:

<examplexml>
    <nest1>
        <nest2>
             <nest3>
                <mean>5</mean>
                <stdeviation>0.1</stdeviation>
             </nest3>
        </nest2>
     </nest1>
    <nest1>
        <nest2>
             <nest3>
                <mean>7</mean>
                <stdeviation>0.2</stdeviation>
             </nest3>
        </nest2>
     </nest1>
</examplexml>

I'm stuck using Liquid on this project and I want to parse this xml. I can get the mean once by doing

{{ file.parse.examplexml.nest1.nest2.nest3.mean }}

but I want to get all the means, so I thought I could do

{% for nest1 in file.parse.examplexml.nest1 %}
  {{ nest1.nest2.nest3.mean }}
{% endfor %}

But this prints out nothing. However if I do

{% for nest1 in file.parse.examplexml.nest1 %}
  {{ nest1 }}
{% endfor %}

I get nest2. So I'd think I can access the mean through the nest2 and nest3 properties, but it doesn't seem to work that way afaik. Is there a way to do this in Liquid? Thanks.
