问题描述

'''

                A stray SKATEBOARD clips her, causing her to stumble and 

      spill her coffee, as well as the contents of her backpack.

      

      The young RIDER dashes over to help, trembling when he sees 

      who his board has hit.

      

                             RIDER

                Hey -- sorry.

      

      Cowering in fear, he attempts to scoop up her scattered 

      belongings.

      

                             KAT

                Leave it 

      

      He persists.

      

                             KAT (continuing)

                I said, leave it!

      

                             RIDER

                Hey -- sorry.

我正在抓取一些我想要进行文本分析的脚本。我只想从脚本中提取对话，看起来它有一定的间距。例如，我想要那行“嘿——对不起。”。我知道间距是 20，这在整个脚本中是一致的。所以我怎么才能只读那一行，其余的行间距相等？

我想说我要使用read.fwf，读取一个固定的宽度。

你们有什么感想？

          Welcome to Padua High School,, your typical urban-suburban 
          high school in Portland, Oregon.  Smarties, Skids, Preppies, 
          Granolas. Loners, Lovers, the In and the Out Crowd rub sleep 
          out of their eyes and head for the main building.
          
          PADUA HIGH PARKING LOT - DAY
          
          KAT STRATFORD, eighteen, pretty -- but trying hard not to be 
          -- in a baggy granny dress and glasses, balances a cup of 
          coffee and a backpack as she climbs out of her battered, 
          baby blue '75 Dodge Dart.
          
          A stray SKATEBOARD clips her, causing her to stumble and 
          spill her coffee, as well as the contents of her backpack.
          
          The young RIDER dashes over to help, trembling when he sees 
          who his board has hit.

                    Hey -- sorry.
          
          Cowering in fear, he attempts to scoop up her scattered 
          belongings.

          She grabs his skateboard and uses it to SHOVE him against a 
          car, skateboard tip to his throat.  He whimpers pitifully 
          and she lets him go.  A path clears for her as she marches 
          through a pack of fearful students and SLAMS open the door, 
          entering school.
          
          INT. GIRLS' ROOM - DAY
          
          BIANCA STRATFORD, a beautiful sophomore, stands facing the 
          mirror, applying lipstick.  Her less extraordinary, but 
          still cute friend, CHASTITY stands next to her.  
          
                                 BIANCA
                    Did you change your hair?
          
                                 CHASTITY 
                    No.
          
                                 BIANCA
                    You might wanna think about it
          
          Leave the girls' room and enter the hallway.
          
          HALLWAY - DAY- CONTINUOUS
          
          Bianca is immediately greeted by an admiring crowd, both 
          boys
          and girls alike.
          
                                 BOY

                                 GIRL
                    Awesome shoes.
          
          The greetings continue as Chastity remains wordless and 
          unaddressed by her side.  Bianca smiles proudly, 
          acknowledging her fans.
