我有以下句子:
trying <- 'Happy CNY to You <-U+2661> Abundance BLESSING to you and your family! <-U+2661> happy and blessed year ahead! '
我想删除所有 <.....>这句话中的实体。我使用了以下函数:
comment = gsub(pattern = "<.*>", replacement = "", x= trying)
但是，我返回的是:
"Happy CNY to You happy and blessed year ahead! "
我可以知道如何编辑代码，以便获得以下内容:
"Happy CNY to You Abundance BLESSING to you and your family! happy and blessed year ahead! "
最佳答案
因为正则表达式匹配是贪婪的。您可以在表达式中放置 ?。
comment = gsub(pattern = "<.*?>", replacement = "", x= trying)
