Ruby正则表达式搜索

Question

我正在编写一个脚本来搜索HTML文本块,%{}以便用动态变量替换它们.

出于某种原因,我的正则表达式无效.

str = "<p>%{urgent_personal_confidential}</p>"

regex = /^%\{(.*)\}/
puts str.match(regex)

我确信这很简单......任何关于可能出错的想法？

Answer 1

Ruby已经将该功能内置到String中.

"The quick brown %{animal1} jumps over the lazy %{animal2}" % { :animal1 => "fox", :animal2 => "dog"  }

结果是

"The quick brown fox jumps over the lazy dog"
