红宝石开始_with？（），结束_with？（）
我有一个文档，其主题标题包含在“|”中人物。
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头是否有效。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
用于解析的文档文本：

I have a document with subject headers being enclosed in "|" characters.
E.g. "| LINKS |"
I want to check the string if it begins and ends with "|" character to verify that the particular document's subject header is valid. How do I do so ?
Source:
@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

您尝试过 RDoc 吗？
Did you try the RDoc?
您可以只使用一个简单的正则表达式：
这样您就可以验证其他内容，例如标头必须全部大写并且周围需要空格（
/^\|\s[AZ]+\s\|$ /）。You can just use a simple regular expression:
That way you can verify other things, like that the header has to be all caps and needs spaces around it (
/^\|\s[A-Z]+\s\|$/).
