我从文本中替换start#character word replace。我的目标是从主题标签文本创建可点击链接
我用过.gsub()。但不行。
示例:
s = "#tag ddd#tagddd #taghh #tag aaaaa #####tag b###tag"
str = "#tag"
s.gsub(/\b"#{str}"\b/), "replaced")
我希望输出“替换ddd#tagddd #taghh替换aaaaa ####替换b ##替换”
谢谢

我不确定这是你在找什么,但也许它会帮助你:
regexp = /#+\w+/
s = "#tag ddd#tagddd #taghh #tag aaaaa #####tag b###tag"
s.gsub(regexp, 'replaced')
我的控制台输出:
1.9.3p489 :001 > regexp = /#+\w+/
=> /#+\w+/
1.9.3p489 :002 > s = "#tag ddd#tagddd #taghh #tag aaaaa #####tag b###tag"
=> "#tag ddd#tagddd #taghh #tag aaaaa #####tag b###tag"
1.9.3p489 :003 > s.gsub(regexp, 'replaced')
=> "replaced dddreplaced replaced replaced aaaaa replaced breplaced"
