Support Google News Sitemaps

Is your feature request related to a problem? Please describe. I am using next.js to build local news websites. I want to ensure they are configured properly for SEO and Google News. Google News requires a specific sitemap format with special fields in order to have your news website populate in Google News.

Describe the solution you’d like In order to support this, next-sitemap would need to allow the population of nested fields. A Google News sitemap requires some specific nested fields. Here’s an example from The New York Times:

<url>
  <loc>
    https://www.nytimes.com/2019/09/30/learning/lesson-of-the-day-kehinde-wileys-times-square-monument-thats-no-robert-e-lee.html
  </loc>
  <lastmod>2021-03-05T20:38:12Z</lastmod>
  <news:news>
    <news:publication>
      <news:name>The New York Times</news:name>
      <news:language>en-US</news:language>
    </news:publication>
    <news:publication_date>2019-09-30T08:00:03Z</news:publication_date>
    <news:title>
      Lesson of the Day: ‘Kehinde Wiley’s Times Square Monument: That’s No Robert E. Lee’
    </news:title>
  </news:news>
  <image:image>
    <image:loc>
      https://static01.nyt.com/images/2019/09/27/arts/27kehinde3/27kehinde3-articleLarge.jpg
    </image:loc>
  </image:image>
</url>

Ideally, when returning an object for a URL either in the transform function or in a dynamic sitemap, I could populate these fields:

return {
  loc: "/2019/09/30/learning/lesson-of-the-day-kehinde-wileys-times-square-monument-thats-no-robert-e-lee.html",
  lastmod: "2021-03-05T20:38:12Z",
  news: {
    publication: {
      name: "The New York Times",
      language: "en-US"
    },
    publication_date: "2019-09-30T08:00:03Z",
    title: "Lesson of the Day: 'Kehinde Wiley’s Times Square Monument: That’s No Robert E. Lee'"
  },
  image: {
    loc: "https://static01.nyt.com/images/2019/09/27/arts/27kehinde3/27kehinde3-articleLarge.jpg"
  }
}

Describe alternatives you’ve considered I could generate this XML file on my own through next.js, but it would be nice to use the same library I’m using to generate the overall sitemap.

For anyone also stuck needing nested field support, I’ve been able to work around it by passing a template literal into in the parent field eg:

{
    "image:image": `
            <image:loc>${imgUrl}</image:loc>
            <image:title>${imgTitle}</image:title>
            <image:caption>${imgCaption}</image:caption>
          `
}
