Thread Subject: Finding legend handle among a figure's children

Does anyone know a way to identify which of a figure's children is a legend?*

At the moment I have a plot with 4 lines in it and a legend. Then get(gca,'children') gives me those handles, while get(gcf,'children') gives me a vector of two handles (one for the legend and one for the axis). I am assuming that the first element in that vector will always point to the legend (since it makes little sense to generate a legend before there is an axis) -- but is that always the case? If not, can anyone suggest a cleaner way to do this?

Thanks in advance,

The legend will have its Tag property set to 'legend' so

  findobj(gcf,'Type','axes','Tag','legend')

should be pretty safe.
