List=[{' level: 1, 'num' : 'a'},
{' level: 1, 'num' : 'ab'},
{' level: 1, 'num' : 'aasdf},
{' level: 2, 'num' : 'as'},
{' level: 2, 'num' : 'sda},
{' level: 3, 'num' : 'asd'},
{' level: 2, 'num' : 'SDWQW},
{' level: 1, 'num' : 'dqwee},
{' level: 1, 'num' : 'sre'},
{' level: 2, 'num' : 'SXZXC},
{' level: 2, 'num' : 'sxzasdxc},
{' level: 3, 'num' : 'SXZSXC},
{' level: 1, 'num' : 'sxasdzxc}]

Level 1 and begin with 'aa' elements, to the next level of 1 elements between delete all

The result is that
[{' level: 1, 'num' : 'a'},
{' level: 1, 'num' : 'ab'},
{' level: 1, 'num' : 'aasdf},
{' level: 1, 'num' : 'dqwee},
{' level: 1, 'num' : 'sre'},
{' level: 2, 'num' : 'SXZXC},
{' level: 2, 'num' : 'sxzasdxc},
{' level: 3, 'num' : 'SXZSXC},
{' level: 1, 'num' : 'sxasdzxc}]
