好吧，我有一个由一些开源软件输出的表格，但它没有以实际的表格格式输出，例如

<table> 
  <thead>
     <td>Heading</td>
  <thead>
  <tbody>
    <tr>
       <td>Content</td>
    </tr>
  <tbody>
</table

相反，开发软件的人认为像这样输出表格是个好主意

+------------+-------------+-------+-------------+------------+---------------+----------+
| HEADING 1  | HEADING 2   | ETC   | ANOTHER     | HEADING3   | HEADING4     | SML |
+------------+-------------+-------+-------------+------------+---------------+----------+
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
+------------+-------------+-------+-------------+------------+--------------+----------+
| TOTALS        AGENTS:21  |  total|        total|       total|         total| total|
+------------+-------------+-------+-------------+------------+--------------+----------+

所以我无法构建一个网络抓取器来获取数据，或者我不确定我是否可以构建一个抓取器来抓取数据，因为它全部包含在一个 <pre> </pre> 中。标签 。因此，我一直在尝试使用 ruby​​ 和 Regex 来尝试完成工作，到目前为止我已经设法获得所有领先的 |出来了，我也设法得到标题 +-------+-----但仅此而已，因为我似乎必须一直重复该模式，它不想重复自己，好吧，但现在已经说得够多了这是我到目前为止使用的代码

text.lines.to_a.each do |line|
   line.sub(/^\| |^\+*-*\+*\-*/) do |match|
    puts "Regexp Match: " << match
end
STDIN.getc
puts "New Line "<< line
end

例如，第一行的输出只会是 +-----------------+---------- 它是 CSV 格式，所以我使用 Gsub替换剩余的 |与,的

我可以使用 PHP 或 Ruby，所以非常欢迎任何答案

最佳答案

这可能不是那么干净，但它适用于这个例子:) ruby :

@text = <<END
+------------+-------------+-------+-------------+------------+---------------+----------+
| HEADING 1  | HEADING 2   | ETC   | ANOTHER     | HEADING3   | HEADING4     | SML |
+------------+-------------+-------+-------------+------------+---------------+----------+
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
| content   | more content | cont  | More more   | content    | content 2.0  | litl |
+------------+-------------+-------+-------------+------------+--------------+----------+
| TOTALS        AGENTS:21  |  total|        total|       total|         total| total|
+------------+-------------+-------+-------------+------------+--------------+----------+
END
s = @text.scan(/^[|]\W(.*)[|]$/)
puts s
arr = []
arr2 = []
s.each do |o|
  a = o.to_s.split('|')
    a.each do |oo|
      arr2 << oo.to_s.gsub('["','').gsub('"]','').gsub(/\s+/, "")
    end
    arr << arr2
  arr2 = []
end
arr.each do |i|
  puts i
end
