Sorry...
start point: $x_at(0) and $y_at(0)
end point: $x_at(-1) and $x_at(-1)
But Jack Andersen's idea is more effective.

Subject: Re: [Qgis-user] Getting lon/lat
Hi phi73,
You can get the Lat long for start and endpoints by using the field
calculator in the attribute table.
create a new field and calculate it with the following:
i.g. field "longXstart" calculate: x(start_point($geometry))
"latYstart" calculate: y(start_point($geometry))
You can do the same for the endpoint by changing start_point with end_point
Furthermore the output will be in the same projection/coordinates as your
layer, but you can do a transform command on the above command with:
x(transform(start_point( $geometry), 'EPSG:25832', 'EPSG:4326')) where the
first epsg code is the current projection and the second one is the target
projection
I have moved the x to the front of the command because the transform
function only works on coodinate sets and i therefore transform x and y and
then extract x.

Hello
i have map based on vector data and in it some street elements.
I would like to pick up a line segment and get the lon/lat for
the start vertex and end vertex.
How could it be done the easiest way in QGIS.
thanks
