我需要的信息，如源IP是在/來源/ IP_ADDRESS，電子郵件發送者，誰是在地址/電子郵件中，字段位於信件的開頭，即信件本身。如何使用Nokogiri在Ruby中實現它？

我試圖獲取數據IP地址如下：

def ip_address 
ip = Nokogiri :: XML ("mail/*. txt") 
ip.each {| node | 
p node.inner_xml if node.name == "IP_Address" 
}

但我沒有出去。有沒有人有想法如何從這種類型的文件中獲取數據？

在將整個電子郵件傳遞給nokogiri之前，您是否咬了一口XML？ – mudasobwa

@mudasobwa不，我以爲nokogiri在文件中識別xml – D7na

嗯，它不。 – mudasobwa

引入nokogiri不會解析郵件，所以你必須擺脫非XML內容：

這是如何將消息分解成XML的：

require 'nokogiri' 
xml = message[/(<\? xml .+)----- BEGIN/m, 1] 
doc = Nokogiri::XML::DocumentFragment.parse(xml) 
doc.at('IP_Address').text # => " 158.01.52.23 "

mag IC型號是：

xml = message[/(<\? xml .+)----- BEGIN/m, 1]

，抓住從<? xml到----- BEGIN前行的一切。然後Nokogiri::XML::DocumentFragment.parse可以創建一個可搜索的DOM。

因爲你似乎只是狩獵的IP地址，我會忘記引入nokogiri：

puts $~[1] if s =~ /<IP_Address>\s*([\d.]+)\s*<\/\s*IP_Address>/m

會做的伎倆假設文件內容加載中s與

s = File.read(...)

希望它可以幫助。

UPD到grep出來的XML：

xml = $~[1] if s =~ /(<\?\s*xml.*?Infringement>)/m

def ip s = Nokogiri :: XML（「mail/*。txt」）如果s =〜/ \ s *（[\ d。] +）\ s */m end return nill – D7na

請忘記nokogiri。如果你的文件是'a.txt'，只要運行'puts $〜[1] if File.read（'a.txt'）=〜/ \ s *（[\ d。] +）\ s * <\ \ s * IP_Address>/m' – mudasobwa

如何在<？xml之前和結束標記之後清除所有內容，並使用nokogiri進行分析？ – D7na
