正则表达式的字符串替换方法

我有以下几行

d:\Projects\qqq\Development\qqq.MySol1.sln
d:\Projects\qqq\qqqDevelopment\qqqMySol2.sln
d:\Projects\qqq\Development\MyInstaller.sln
d:\Projects\qqq\qqq\Development\MyInstaller.sln
d:\Projects\Development\MyInstaller.sln

我需要一个正则表达式，这将导致捕获

Line 1: Development and MySol1.sln
Line 2: Development and MySol2.sln
Line 3: Development and MyInstaller.sln
Line 4: Development and MyInstaller.sln
Line 5: Development and MyInstaller.sln

，一个正则表达式，将删除（忽略）字qqq从行。 我一直在试图与调节，并有部分的解决方案

这导致

Line 1: Development and .MySol1.sln
Line 2: qqqDevelopment and MySol2.sln
Line 3: Development and nstaller.sln
Line 4: Development and nstaller.sln
Line 5: Development and nstaller.sln

，.{3}应固定

1.我认为，应该工作

.\\(?:qqq)?(?<A>.)\\(?:qqq)?(?<B>.)
