当我对使用
ruby的特定单词之间包含的文本感兴趣时,我想知道如何继续.
例如.
例如.
@var = "Hi,I want to extract container_start ONLY THIS DYNAMIC CONTENT container_end from the message contained between the container_start and container_end "
现在我想从字符串中提取CAPITALIZED内容,即动态但始终包含在两个容器中(container_start和container_end)
解决方法
简单的正则表达式会：
@var = "Hi,I want to extract container_start **ONLY THIS DYNAMIC CONTENT** container_end from the message contained between the container_start and container_end " @var[/container_start(.*?)container_end/,1] # => " **ONLY THIS DYNAMIC CONTENT** "
