Check value within array in template

Hi,

I have created a file type which returns an array, which works great, I simply want to check if a value within the array exists.

<perch:if exists="venue-link['profile']" >
                <div class="col-md-3"><img class="img-responsive" src="<perch:events id="venue-link" type="teamlist" output="profile" />"></div>
                <div class="col-md-9">
                <perch:else />
     <div class="col-md-12">
</perch:if>

Can it be done?

Here is the returned array
