請(qǐng)問(wèn)怎樣實(shí)現(xiàn)對(duì)文本中每一行特定字符后的數(shù)值進(jìn)行等量的加法運(yùn)算

原文件如下:
(globals
    version = 3
    io_order = default
)
(iopin
    (bottom
        (pin name="COE"        offset=22.0000 layer=4 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="MOON"        offset=26.0000 layer=4 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="TYPE"        offset=30.0000 layer=4 width=0.2000 depth=0.6000 place_status=fixed  )
)
    (left
        (pin name="AMB"        offset=22.0000 layer=3 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="END"        offset=26.0000 layer=3 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="TOU"        offset=30.0000 layer=3 width=0.2000 depth=0.6000 place_status=fixed  )
)
......
先找到bottom所屬的區(qū)間,然后將每一行offset=后面的數(shù)值均增加100,再找到left所屬的區(qū)間,然后將每一行offset=后面的數(shù)值均增加0.5結(jié)果如下:
(globals
    version = 3
    io_order = default
)
(iopin
    (bottom
        (pin name="COE"        offset=122.0000 layer=4 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="MOON"        offset=126.0000 layer=4 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="TYPE"        offset=130.0000 layer=4 width=0.2000 depth=0.6000 place_status=fixed  )
)
    (left
        (pin name="AMB"        offset=22.5000 layer=3 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="END"        offset=26.5000 layer=3 width=0.2000 depth=0.6000 place_status=fixed  )
        (pin name="TOU"        offset=30.5000 layer=3 width=0.2000 depth=0.6000 place_status=fixed  )
)
