grep 正则

SafeArray::SafeArray(int len) {
    length = len;
    _array = new int[length];
}


CPoint::CPoint() : x(0), y(0)
{   /* Nothing to do! */  }


CPoint::CPoint()
{   x = 0; y = 0;  }

CPoint::CPoint(int x, int y)
{   this->x = x;
    this->y = y;  }

CPoint::CPoint(const CPoint &p)
{   x = p.x;
    y= p.y;  }

可以过滤出上面的建构函数

CPoint::CPoint(const CPoint &p)
CPoint::CPoint()
CPoint::CPoint() : x(0), y(0)
SafeArray::SafeArray(int len)
[解决办法]
Perl正则，过滤掉你要求的部分的留下部分，供参考。
先写了下\{([^}])*\}\n
再写了下((?<!:):[^:]*)?\{([^}])*\}\n
