我需要信息，例如发送方IP，在/ Source / IP_Address，电子邮件发件人，谁在地址/电子邮件，来自字段位于信件的开头，信件本身。如何使用Nokogiri在Ruby中实现它？

我试图获取数据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" 
}

但我没有出去。有没有人知道如何从这种类型的文件中获取数据？

Answer 1

由于您似乎只是在寻找IP地址，我会忘记nokogiri：

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

假设文件内容已加载到s

，

就可以了

s = File.read(...)

希望它有所帮助。

UPD 要格式化XML：

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

Answer 2

Nokogiri不会解析邮件消息，所以你必须摆脱非XML内容：

message = 'From: XXX <xxx@xxx.com> 
To: yyy@yyy.com 
Subject: Sabertooth; zebra oto Hammerjaw pompano, cusk-eel lighthousefish frogmouth catfish.

这是如何将消息分解为XML：

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

神奇的部分是：

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

抓取从<? xml到----- BEGIN之前的行的所有内容。然后Nokogiri::XML::DocumentFragment.parse可以创建一个可搜索的DOM。

查找XML内容
