Task forms

I want to retrieve the task form using the ReST API.
When I try to fetch the form,I recieve the form with the UI styling such as div and class.
How can I retrive the form xml without any UI styling such as

<camunda:formField id=“name” label=“Name” type=“string” />
<camunda:formField id=“empId” label=“Employee Id” type=“long” />
<camunda:formField id=“active” label=“Active” type=“boolean” />
<camunda:formField id=“severity” label=“Severity” type=“enum”>
<camunda:value id=“needservice” name=“Needs Service” />
<camunda:value id=“notok” name=“Not Ok” />
<camunda:value id=“ok” name=“Ok” />
<camunda:formField id=“startDate” label=“Start Date” type=“date” />
<camunda:formField id=“endDate” label=“End Date” type=“date” />
