Ruby - 遍历nokogiri元素

Question

我有一个这样的 html:

...
<table>
<tbody>
    ...
    <tr>
    <th> head </th>
    <td> td1 text<td>
    <td> td2 text<td>
    ...
    </tr>
</tbody>
<tfoot>
</tfoot>
</table>

...

我将 Nokogiri 与 ruby​​ 结合使用。我想遍历每一行并将 th 和对应的 td 的文本放入哈希中。

Answer 1

require "nokogiri"

#Parses your HTML input
html_data = "...stripped HTML markup code..." 
html_doc = Nokogiri::HTML html_data

#Iterates over each row in your table
#Note that you may need to clarify the CSS selector below
result = html_doc.css("table tr").inject({}) do |all, row|

  #Modify if you need to collect only the first td, for example
  all[row.css("th").text] = row.css("td").text

end
