使用Nokogiri，如何用一个新标记将元素的文本内容包装起来?

I have an Nokogiri::XML::Element in which looks like this:

我有一个Nokogiri::XML::元素，它看起来像这样:

<div class="berg">This is some text!</div>

What I want to do is just extract the text from the div (which is the Nokogiri Element) and then wrap the text with a new tag so it looks like this:

我要做的就是从div(即Nokogiri元素)中提取文本，然后用一个新的标签将文本包装起来，就像这样:

<div class="berg"><span>This is some text!</span></div>

The Nokogiri .wrap functions seems to wrap tags, not their text contents with a new tag, I was wondering how you wrap the inter tag contents. Cheers.

包装函数似乎是包装标签，而不是用新的标签来包装它们的文本内容，我想知道如何包装标签内容。欢呼。

Edit: Took the answer below and did it very simply like this in one line:

编辑:把下面的答案写在一行中，非常简单:

      tag.inner_html = "<span>#{tag.inner_html}</span>"

2 个解决方案

#1

You can set the inner_html of the div element. Here's a working example:

可以设置div元素的inner_html。这里有一个工作示例:

html = '<div class="berg">This is some text!</div>'
doc = Nokogiri::HTML.fragment(html)

berg = doc.at('div.berg')    # Or xpath, or whatever method you choose

# Wrap the text in <span>
berg.inner_html = "<span>#{berg.text}</span>"

puts doc  #=> <div class="berg"><span>This is some text!</span></div>

The important part is the use of inner_html, adding in the <span> element and putting the existing text element inside it.

重要的部分是使用inner_html，添加元素并将现有的文本元素放入其中。

You would do:

你会做的事:

doc.search('div.berg text()').wrap('<span>')
