Can't extract summary with nested div

[swiftcoder]

I'm trying to parse an atom feed that has a div tag nested inside the summary element:

 <summary type='xhtml'><div xmlns='http://www.w3.org/1999/xhtml'>Old software joke: “After the apocalypse, all that’ll be left will be cockroaches, Keith Richards, and markup characters     that have been escaped (or unescaped) one too many (or few) times.</div></summary>

The summary object ends up looking like this:

{div: {#text: "Old software joke: “After the apocalypse, all that…", @_xmlns: "http://www.w3.org/1999/xhtml"}, @_type: "xhtml"}

It appears that getText() only checks for a #text property on the root object, so it returns an empty string here, because the #text property is on the nested div element.

As a workaround for this on my side, I've written a little helper function to recursively find the first text node:

function recursiveFindText(input: any): string {
  let text =
    input["_text"] ??
    input["#text"] ??
    input["_cdata"] ??
    input["$t"] ??
    (typeof input === "string" ? input : undefined);
  if (!text) {
    for (const property in input) {
      text = recursiveFindText(input[property]);
      if (text) {
        break;
      }
    }
  }
  return text;
}

function extractDescription(input: any) {
  const text = recursiveFindText(input);
  if (text) {
    return bellajs.truncate(bellajs.stripTags(text), 250);
  }
}

And I'm applying it in getExtraEntryFields to overwrite the blank value:

        getExtraEntryFields: (feedEntry: any) => {
          return {
            description:
              extractDescription(feedEntry.description) ??
              extractDescription(feedEntry.summary) ??
              extractDescription(feedEntry.content),
          };
        },
