Using Nokogiri, I would like to determine the name of the root element.
使用Nokogiri,我想确定根元素的名称。
I thought that doing an XPath query for /
would do the trick but apparently that node name is "document"?
我认为对/做一个XPath查询可以做到这一点,但显然节点名称是“文档”?
require 'nokogiri'
doc = Nokogiri::XML('<foo>Hello</foo>')
doc.xpath('/').first.name # => "document"
doc.xpath('/foo').first.name # => "foo"
How can I get the string "foo" for the root node name without knowing it ahead of time?
如何在不事先知道根节点名的情况下获取字符串“foo”?

doc = Nokogiri::XML('<foo>Hello</foo>')
doc.xpath('/*').first.name

或使用Nokogiri :: XML :: Document #root:
doc.root.name
