[boost] [lambda] how can I access structure member

Suppose I have the following structure:

   struct xy { int x, y; };

and the following vector:

   vector<xy> v(10);

I want to use lambda library for find an item in the table.
Let's say, with x member value equal to 10.
Something like this doesn't work:

   pos = find_if(v.begin(), v.end(), _1.x == 10);

How the above line should be written ?
