如何改变…在 Ruby 中（省略号）到 ...（三个句点）？
我正在使用 nokogiri 解析此文档 。我发现该页面中有一些 ... （省略号）字符并且无法删除。我想知道如何使用 Ruby 将所有 ... （省略号）替换为 ... （三个句点）。
顺便说一句，您可以搜索此字符串来查找所有 ...s

s.gsub!(k, v)
end

temp = []
doc.xpath('//div[@class="tableSection"]/table[position() = 1]/tr').each do |e|
temp << e.css("td, th").map(&:text).map(&:strip).map {|x| x = change x; x.split(/\n/).map {|z| z.gsub(/.{80}/mi, "\\0\n")}.join("\n")}
end
table = Terminal::Table.new
table.headings = temp.shift
table.rows = temp
puts table

I'm parsing this document using nokogiri. I found there are some … (elipses) characters in that page and can't be removed. I want to know how to use Ruby to replace all … (elipses) to ... (three periods).
BTW, you can search this string to find all …s
Specifies whether ALTER TABLE
Edit:
I added my program and the error message.

它可能取决于您正在使用的文件的编码，但尝试使用
单字符 3 点，又名“水平省略号"（您要替换的）。
It probably depends on the encoding of the file you're working with, but try using
for the single-character 3-dots aka "horizontal ellipsis" (the one you want to replace).
我只是先 String#tr 。
然后运行 Nokogiri ......
I'd just String#tr on it first.
And run Nokogiri on that...
