如何在Ruby中修改字符串？

Question

如果我有一个字符串是这样的：

a = "11003.20140314143116.11003#13947822765031.ssint1.natvoice_nowithin_2txns.translatedalreadytotxt.pdf" 
b = "11003.20140314143454.11003#13947824943836.ssint1.natvoice_nowithin_2txns.translatedalreadytotxt.pdf" 
c = "11003.20140303131136.11003#13938270964818.telstra-alltxns-live_stripped-1.translatedalreadytotxt.pdf" 

...我怎么修改它们在Ruby中导致这样的：

a = "ssint1.natvoice_nowithin_2txns.translatedalreadytotxt.pdf" 
b = "ssint1.natvoice_nowithin_2txns.translatedalreadytotxt.pdf" 
c = "telstra-alltxns-live_stripped-1.translatedalreadytotxt.pdf" 

Answer 1

所以，你要的字符串A〜Z开头？

result = a.gsub(/\A[^a-z]*/, '') 

如果你想改变原来的字符串，然后使用

a.gsub!(/\A[^a-z]*/, '')
