ruby start_with?(), end_with?()

Question

我有一个主题标题被包含在“|”中的文档字符。

例如“|链接|”

我想检查字符串是否以“|”开头和结尾字符来验证特定文档的主题标题是否有效。我该怎么做？

来源:

@filetarget = " < document file location here > "

@line = ""

file = File.new(@filetarget)

while (@line = file.gets)
   if((@line.start_with?("|")) and (@line.end_with?("|")))
      puts "Putting: " + @line
   end
end

要解析的文档文本:

| LINKS |

你试过RDoc了吗？ ？

"| LINKS |".start_with?("|") # => true
"| LINKS |".end_with?("|") # => true
