带有 Nokogiri 的脚本标记中的目标元素

Question

任何人都可以帮助我使用 Nokogiri 从这个脚本标签中提取作者姓名。

到目前为止，我可以使用以下方法访问脚本标签：

parsed_page.xpath("//脚本[@type ='application/ld+json']")

我正在尝试获取“Kevin McCart”这个名字

<script type="application/ld+json">{"@context":"https:\/\/schema.org","@type":"NewsArticle","headline":"OLYMPICS: Check out schedule","url":"https:\/\/www.website.ie\/sport\/winter-olympics-check-out-jack-gowers-schedule-4237649","mainEntityOfPage":{"@type":"WebPage","@id":"https:\/\/www.southernstar.ie\/sport\/winter-olympics-check-out-jack-gowers-schedule-4237649"},"dateCreated":"2022-02-04T12:00:40+00:00","datePublished":"2022-02-04T12:00:40+00:00","dateModified":"2022-02-02T15:08:29+00:00","thumbnailUrl":"https:\/\/images.website.ie\/uploads\/2022\/01\/24153939\/Jack-Gower-cropped.jpg","image":{"@type":"ImageObject","url":"https:\/\/images.website.ie\/uploads\/2022\/01\/24153939\/Jack-Gower-cropped.jpg","width":700,"height":370},"articleSection":"Sport","keywords":"Jack Go","author":[{"@type":"Person","name":"Kevin McCart"}],"publisher":{"@type":"Organization","name":"The Southern Star","logo":{"@type":"ImageObject"}}}</script>

任何帮助将不胜感激。

谢谢，

杰拉德

一旦你到达脚本标签，nokogiri 的工作就完成了，是时候解析了 JSON。

require 'json'
def get_kevin(script_element)
  data = JSON.parse(script_element.text)
  data.fetch("author").first.fetch("name")
end
