<div class="pg-list">

CodePudding user response：

You could do it like this, since you say you want to remove <br> that is between 2 x <a>:

$('.ch-list p br').filter(function() {
  if ($(this).prev().is("a") && $(this).next().is("a")) {
    return this
  }
}).remove()

Demo

Show code snippet

$('.ch-list p br').filter(function() {
  if ($(this).prev().is("a") && $(this).next().is("a")) {
    return this
  }
}).remove()
