如何在Nokogiri :: XML :: Text對象中使用正則表達式？

Question

我有一個數組稱這些對象的人：

Nokogiri::XML::Text:0x3fe41985e69c "CEO, Company_1" 
Nokogiri::XML::Text:0x3fe4194dab74 "COO, Company_2 " 
Nokogiri::XML::Text:0x3fe4195eb414 "CFO, Company_3" 

我想的對象在拆分「」所以我試圖做這樣的事情：

companies = people.each do | company | 
    company.inner_text.match("/, (.*)/") 
end 

和：

occupations = people.each do | occupation | 
    occupation.inner_text.match("/(.*),/") 
end 

match似乎並沒有提取我從對象所需的值。我檢查rubular.com，它應該工作，但我發現我放在同一個字符串："CEO, Company_1"當它應該被分開，這樣occupations = [CEO, COO, CFO]和companies = [Company_1, Company_2, Company_3]。

我如何拆分這些對象呢？

Answer 1

你爲什麼不split的文本？

require 'nokogiri' 

xml = '<x> 
<people>CEO, Company_1</people> 
<people>COO, Company_2</people> 
<people>CFO, Company_3</people> 
</x> 
' 

doc = Nokogiri::XML(xml) 
people = doc.search('people') 
companies = people.map do |company| 
    company.text.split(',') 
end 

pp companies 

=> [["CEO", " Company_1"], ["COO", " Company_2"], ["CFO", " Company_3"]] 

如果你想在公司前擺脫前導空格，使用方法：

companies = people.map do |company| 
    company.text.split(/,\s*/) 
end 
=> [["CEO", "Company_1"], ["COO", "Company_2"], ["CFO", "Company_3"]] 

或者：

companies = people.map do |company| 
    company.text.split(',').map(&:lstrip) 
end 
=> [["CEO", "Company_1"], ["COO", "Company_2"], ["CFO", "Company_3"]] 

或者使用map{ |s| s.sub(/^\s+/, '') }代替lstrip。

見 「How to avoid joining all text from Nodes when scraping」 也。
