Question

可能重复：
ruby code for modifying outer quotes on strings?

这是我的字符串：

msgid """We couldn't set up that account, sorry.  Please try again, or contact an ""admin (link is above)."

我想删除除第一个和最后一个之外的所有双引号。我该怎么办？

Answer 1

只要您知道在开头和结尾总是需要引用，这是一个选项。

假设x持有你想要操纵的刺痛。

x = '"' + x.gsub('"', '') + '"'

Answer 2

这假设您的字符串将始终为上面显示的“msgid ...”格式，并且您的意图输出为“msgid”文本“'：

>> str.gsub(/(msgid )"{1,}(.*) "{1,}(.*)"/, '\1"\2 \3"')
=> "msgid "We couldn't set up that account, sorry.  Please try again or contact an admin (link is above).""
>> puts str.gsub(/(msgid )"{1,}(.*) "{1,}(.*)"/, '\1"\2 \3"')
msgid "We couldn't set up that account, sorry.  Please try again or contact an admin (link is above)."

Answer 3

我会选择这样的事情：

msg = %q{msgid """We couldn't set up that account, sorry.  Please try again, or contact an ""admin (link is above)."}
print 'msgid "' << msg.sub('msgid ', '').gsub('"', '') << '"'
# >> msgid "We couldn't set up that account, sorry.  Please try again, or contact an admin (link is above)."

如果“msgid”在每一行之前，则删除它，通过剥离它们来处理双引号，然后放回“msgid”并再次添加所需的前导和尾随双引号。

Answer 4

msgid实际上是3个字符串，因为双引号的字符串分隔符。所以你可以：

msgid = ""<<"We couldn't set up that account, sorry. Please try again, or contact an "<<"admin (link is above)."

或者如果你想走很长的路：

x = %q{}
  msgid = """We couldn't set up that account, sorry. Please try again, or contact an ""admin (link is above)."
  x << msgid
  x.gsub!('"', '')
  msgid = ""
  msgid << x
# Check
  puts x
