Publisher field appending random values

[pieroliviermarquis]

The publisher field is appending values that appear to be random. Here is an example:

category: "Apple Inc."
description: "Apple Inc. Stock Has Become an Excellent Choice for Value Investors  Investorplace.comIs It Time To Buy Apple Inc (NASDAQ:AAPL)?  Simply Wall StDigging Up the Facts on Apple Inc. (AAPL)  StockNewsJournalApple Inc. - AAPL - Stock Price Today - Zacks  ZacksFull coverage"
link: "https://investorplace.com/2018/03/apple-stock-excellent-choice/"
pubDate: "Wed, 7 Mar 2018 15:22:53 GMT"
publisher: "Investorplace.comSimply Wall StStockNewsJournalZacks"
thumbnailUrl: "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTny_q_sZ5tjUSjI5FtgTZmNZrVtbvq9vYFuOHW86KKLNsU3JWxpcTFSVhIrw1fiM8EXh80EisPsw8"
title: "Apple Inc. Stock Has Become an Excellent Choice for Value Investors"

Simplay Wall St and StockNewsJournalZacks are not in this object anywhere. The behavior also seems random.

@pieroliviermarquis It's probably because I'm using a pretty noobie approach to parsing the publisher fields, I may need to change it to something a bit more concrete.
