I have the above structure for my html. I want to insert some content in yyy position. Can you tell me what will be a selector for him? I would pass this selector to some function and this function would execute$(selector).html('content')

var s = $('#foo span');
$('#foo').text("hello").append(s);

Or, if updating HTML is an option, then just wrapping it yyyin <span>will make your life a lot easier:

$('#foo span:first-child').text("hello");
