Parse XML and get data of certain tags to CSV Python

I'm trying to parse the following XML file and get output to a CSV file like below. I tried elementree. However, it prints in output.

trial.xml

<?xml version="1.0">
<!-- random text -->
<!-- random text -->
<meta>
    <valID>
        <ValueID>age</ValueID>
        <desc>Physical attributes | Age at time of evaluation</desc>
        <group>
            <ord>1</ord>
            <name>0 - &lt;5</name>
            <min>0</min>
            <mininc>TRUE</mininc>
            <max>5</max>
            <maxinc>FALSE</maxinc>
        </group>
        <group>
            <ord>2</ord>
            <name>5 - &lt;10</name>
            <min>5</min>
            <mininc>TRUE</mininc>
            <max>10</max>
            <maxinc>FALSE</maxinc>
        </group>
    </valID>
</meta>

output.csv

ValueID,name,min,maxinc
age,1,0-<5,0,5
age,5-<10,5,10

Code I tried:

from xml.etree import ElementTree
document = ElementTree.parse( 'trial.xml' )
for d in document.findall('meta/valID/ValueID'):
    print d.text
