有没有办法选择一个节点的所有内容? [英] Is there a way to select all the contents of a node?

问题描述

是否可以选择Nokogiri中节点的所有内容?

Is there a way to select all the contents of a node in Nokogiri?

<root>
    <element>this is <hi>the content</hi> of my æøå element</element>
</root>

获取/root/element内容的结果应该是:

The result of getting the content of /root/element should be:

this is <hi>the content</hi> of my æøå element

似乎解决方案就是简单地使用myElement.inner_html().实际上，我遇到的问题是我依靠的是旧版本的libxml2，该版本转义了所有特殊字符.

It seems like the solution is simply to use myElement.inner_html(). The problem I had was in fact that I was relying on an old version of libxml2, which escaped all the special characters.

推荐答案

Nokogiri.parse('<root><element>this is <hi>the content</hi> of my element</element></root>').css('element').inner_html

如果要转义，可以使用CGI.unescape方法:

If you want escape that, you can with CGI.unescape method:

require 'cgi'
x = Nokogiri.parse('<root><element>this is <hi>the content</hi> of my element</element></root>').css('element').inner_html
CGI.unescape(x)
