如何在Ruby中集成这两个条件块代码？

如果我的代码在没有它们的情况下擦除，我如何整合这两个条件？ 我的代码已经工作了，但是它会擦除所有行（非粗体和粗体值）并且不会刮掉title属性字符串。

---

条件1： 仅当其中一个字段为粗体时才解析表格行 ：

doc = Nokogiri::HTML(html) doc.xpath('//table[@class="articulos"]/tr[td[5]/p/b]').each do |row| puts row.at_xpath('td[3]/text()') end 

---

Condition2： 只获取title属性字符串中的数字 ：

 doc = Nokogiri::HTML(html) numbers = doc.xpath('//p[@title]').collect { |p| p[:title].gsub(/[^\d]/, '') } 

---

我的代码：

 doc = Nokogiri::HTML(search_result.body) rows = doc.css("table.articulos tr") i = 0 details = rows.each do |row| detail = {} [ [:sku, 'td[3]/text()'], [:desc, 'td[4]/text()'], [:qty, 'td[5]/text()'], [:qty2, 'td[5]/p/b/text()'], [:price, 'td[6]/text()'] ].each do |name, xpath| detail[name] = row.at_xpath(xpath).to_s.strip end i = i + 1 detail end 

第二次尝试：

  doc = Nokogiri::HTML(search_result.body) rows = doc.xpath('//table[@class="articulos"]/tr[td[5]/p/b]') i = 0 details = rows.each do |row| detail = {} [ [:sku, 'td[3]/text()'], [:desc, 'td[4]/text()'], [:stock, "td[5]/p[@title]"], [:price, 'td[6]/text()'] ].each do |name, xpath| detail[name] = row.at_xpath(xpath).to_s.strip end i = i + 1 if detail[:sku] != "" price = detail[:price].split if price[1] == "D" currency = 144 else currency = 168 end stock = detail[:stock].gsub(/[^\d]/, '-') cost = price[0].gsub(",", "").to_f end 

股票而不是只是刮掉标题字符串它刮擦整个段落

当我只想要title属性中的2时

Answer 1

这是我未经测试的尝试来解决这个问题：

 doc = Nokogiri::HTML(search_result.body) rows = doc.xpath('//table[@class="articulos"]/tr[td[5]/p/b]') i = 0 details = rows.each do |row| detail = {} [ [:sku, 'td[3]/text()'], [:desc, 'td[4]/text()'], [:stock, 'td[5]/p[@title]'], [:price, 'td[6]/text()'] ].each do |name, xpath| if name == :stock detail[name] = row.at_xpath(xpath).collect { |p| p[:title].gsub(/[^\d]/, '') } else detail[name] = row.at_xpath(xpath).to_s.strip end end i = i + 1 detail end 

Answer 2

这是我的工作代码。 也许需要一点清洁，但它的工作原理。 结果是正确的，但我得到了很多。

 doc = Nokogiri::HTML(search_result.body) rows = doc.xpath('//table[@class="articulos"]/tr[td[5]/p/b]') i = 0 details = rows.each do |row| detail = {} [ [:sku, 'td[3]/text()'], [:desc, 'td[4]/text()'], [:stock, "td[5]/p/@title"], [:price, 'td[6]/text()'] ].each do |name, xpath| detail[name] = row.at_xpath(xpath).to_s.strip end i = i + 1 if detail[:sku] != "" price = detail[:price].split if price[1] == "D" currency = 144 else currency = 168 end stock = detail[:stock].each do |anchor| puts anchor['title'] end stock1 = stock.gsub(/[^\d]/, '') cost = price[0].gsub(",", "").to_f end
