Django delete formset

I have a template where the user search for some records to delete.

I am having troubles trying to figure out how to delete multiple records from a model.

    def XMLFieldsView(request):
        if request.method == 'POST':
           lista = request.POST.getlist('eliminar')
           """ Here I am lost """
        else:
           lista = 'nada'
           form = BuscarServicioForm()
           idxml = request.GET.get('id_xml')
           tabla = XMLFORMTable(XML_FORM.objects.filter(id_xml = 00))
           try:
              idxml = idxml
           except ValueError:
              idxml = 00
           if idxml:
              tabla = XMLFORMTable(XML_FORM.objects.filter(id_xml = idxml))
           RequestConfig(request,paginate={"per_page":60}).configure(tabla)


        return render_to_response('listacampos.html',
                                  {'table':tabla,'form':form,'lista':lista},
                                  context_instance=RequestContext(request))

The user using the form

BuscarServicioForm pick a group of records, where he can choose which records to delete.

But I don't if I need to do this with a formset or I can take the value from the table turning the HTML table into a form

<form method="POST" id="table_form">
<table >
....
</table>
<input type="submit">
</form>

and get the post data to delete the records.

I am using django-tables2 to render the table in this way:

TEMPLATE_CHECK = """
<span class="input-group-addon">
        <input type="checkbox" id="id_eliminar" name="eliminar">
</span>
"""
class XMLFORMTable(tables.Table):
      eliminar = tables.TemplateColumn(TEMPLATE_CHECK,verbose_name='Eliminar')
      class Meta:
            model = XML_FORM
            exclude = ['id_form','obs']

I was thinking to use a formset but I don't how to do that.

Any advice or guide please

Thanks in advance

The html template has to know the pk of the object to get the list of the objects. 

class XMLFORMTable(tables.Table):
      eliminar = tables.CheckBoxColumn(accessor='pk')
      class Meta:
            model = XML_FORM
            exclude = ['id_form','obs']

If you give the pk to the value of the checkbox, you retrieve the value list of checked elements.

import render

def XMLFieldsView(request):
    if request.method == 'POST':
       lista = request.POST.getlist('eliminar')
       """ Here I am lost """
       for pk in lista:
           get_object_or_404(ElObjeto, pk=pk).delete()
    else:
       ....

    return render(request, listacampos.html,{'table':tabla,'form':form,'lista':lista})

Also render, is a shortcut for render_to_response in that will automatically use RequestContext
