如何合并 3 个哈希值？答案

【问题标题】：How to merge 3 hashes?如何合并 3 个哈希值？

【问题描述】：

我一直在尝试从表中获取一些信息到散列中，所以这是我有一个如下所示的 HTML 表的代码，我提取 party_names 和类型并将它们合并到单个散列中。现在我需要将另一个散列与派对地址合并。我能够获得地址，但表结构有点不寻常，所以我不确定如何将参与方地址与拥有该地址的参与方名称合并。

我目前的输出是这样的

{:part_name=>"SMALL,  DANIEL", :party_type=>"Appellant  &nbsp"}
{:part_name=>"KELLY,  MARK EDWARD", :party_type=>"Attorney for Appellant"}
{:part_name=>"PITTMAN,  KRISTI LANAE", :party_type=>"Co-Counsel for Appellant"}
{:part_name=>"RED SIMPSON,  INC.", :party_type=>"Respondent   "}
{:part_name=>"GREENWALD,  DOUGLASMARK", :party_type=>"Attorney for Respondent"}
{:part_name=>"BENJAMIN,  SAMANTHA NICOLE", :party_type=>"Co-Counsel for Respondent"}

我如何获得聚会地址，但如何将其与@party_names_and_types所以我有这样的输出

{:part_name=>"SMALL,  DANIEL", :party_type=>"Appellant  &nbsp"}
{:part_name=>"KELLY,  MARK EDWARD", :party_type=>"Attorney for Appellant", :party_address => "134 N WATER STREETLIBERTY,MO 64068"}
{:part_name=>"PITTMAN,  KRISTI LANAE", :party_type=>"Co-Counsel for Appellant",:party_address => "134 N WATER STREETLIBERTY,MO 64068"}
{:part_name=>"RED SIMPSON,  INC.", :party_type=>"Respondent  "}
{:part_name=>"GREENWALD,  DOUGLASMARK", :party_type=>"Attorney for Respondent", :party_address => " 10 EAST CAMBRIDGE CIRCLE DRIVE KANSAS CITY,KS 66103"}
{:part_name=>"BENJAMIN,  SAMANTHA NICOLE", :party_type=>"Co-Counsel for Respondent", :party_address => "    MCANANY VAN CLEVE AND PHILLIPS  10 E CAMBRIDGE CIRCLE DR STE 300 KANSAS CITY,KS 66103", :party_des => "Business:(913) 573-3319"}

【解决方案1】：

你说的表结构“有点不寻常”是对的。你实现的逻辑，我不会说它是错的，但对于这个表，我不会去用它，因为关联的值（如派对名称和派对地址）在不同的行中。

这是我为获得您提到的预期输出而编写的代码

require 'nokogiri'

# html = 'your provided html code...'

doc = Nokogiri::HTML(html)
rows = doc.xpath("//table[@class='detailRecordTable']//tr")

@party_names_and_types = []

start = 0
step  = 5

def format_text(text)
  text.strip.gsub("  ", "").gsub("
", ' ').gsub("	", '')
end

def get_party_name_and_type(text)
  parts = text.split(',')
  name = parts.length == 3 ? "#{parts[0]}, #{parts[1]}" : parts[0]
  party_type = format_text(parts[-1].strip) if parts && parts.length >= 2
  { party_name: name, party_type: party_type }
end

while start < rows.count
  data_rows = rows.slice(start, step)
  [0, 3].each do |row_num|
    if row_num == 0
      [1, 3].each do |col_num|
        party_details = get_party_name_and_type(
          format_text(data_rows[row_num].children.filter("td")[col_num].text)
        )
        address = data_rows[row_num+1].children.filter("td")[3].text if col_num == 3
        party_details[:party_address] = format_text(address) unless address.nil? || address.empty?
        @party_names_and_types << party_details
      end
    else
      party_details = get_party_name_and_type(
        format_text(data_rows[3].children.filter("td")[3].text)
      )
      address = data_rows[row_num+1].children.filter("td")[3].text
      party_details[:party_address] = format_text(address) unless address.nil? || address.empty?
      @party_names_and_types << party_details
    end
  end
  start += step
end

puts "======@party_names_and_types======"
puts @party_names_and_types

输出：

======@party_names_and_types======
{:party_name=>"SMALL ,  DANIEL", :party_type=>"Appellant  &nbsp"}
{:party_name=>"KELLY ,  MARK EDWARD ", :party_type=>"Attorney for Appellant", :party_address=>"134 N WATER STREETLIBERTY, MO 64068"}
{:party_name=>"PITTMAN ,  KRISTI LANAE ", :party_type=>"Co-Counsel for Appellant", :party_address=>"134 NORTH WATER STREETLIBERTY, MO 64068"}
{:party_name=>"RED SIMPSON,  INC. ", :party_type=>"Respondent   "}
{:party_name=>"GREENWALD ,  DOUGLAS MARK ", :party_type=>"Attorney for Respondent", :party_address=>"10 EAST CAMBRIDGE CIRCLE DRIVEKANSAS CITY, KS 66103"}
{:party_name=>"BENJAMIN,  SAMANTHA NICOLE ", :party_type=>"Co-Counsel for Respondent", :party_address=>"MCANANY VAN CLEVE AND PHILLIPS10 E CAMBRIDGE CIRCLE DRSTE 300KANSAS CITY, KS 66103  Business:(913) 573-3319"}

我会在一段时间内更新答案以解释逻辑。
希望这可以帮助。
