How to display the section name in breadcrumbs in Bitrix?

Question

1C-Bitrix

Hello!
There is a problem with breadcrumbs on Bitrix: in paragraphs, the names from the h1 section field are displayed. And since they are long enough, it turns out ugly: prntscr.com/fur02l
How can I display in paragraphs just the name of the section from here prntscr.com/fur0vu
The code is below:

<?
use \Yenisite\Core\Catalog;

if (!defined("B_PROLOG_INCLUDED") || B_PROLOG_INCLUDED !== true) die();
CModule::IncludeModule('yenisite.core');
//delayed function must return a string
if (empty($arResult))
  return "";
global $rz_b2_options, $rz_current_sectionID;
$bShowBacknav = ($rz_b2_options['backnav_enabled'] == 'Y') && (int)$rz_current_sectionID > 0;
$strReturn = '<div class="breadcrumbs-content"><ul class="b-list" itemscope itemtype="http://schema.org/BreadcrumbList">';
$strReturn .= '<li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem">';
$strReturn .= '<a href="' . SITE_DIR . '"><i class="flaticon-home1"></i><meta itemprop="name" content="' . SITE_SERVER_NAME . '" /></a>';
$strReturn .= '<i class="separator flaticon-right20"></i> <meta itemprop="position" content="1" /></li> ';
$num_items = count($arResult);
$strBacknav = '';
for ($index = 0, $itemSize = $num_items; $index < $itemSize; $index++) {
  $arSiblings = array();
  if ($bShowBacknav) {
    $arSiblings = Catalog::getChainSiblings($rz_current_sectionID, $arResult[$index]["LINK"]);
  }
  $title = htmlspecialcharsex($arResult[$index]["TITLE"]);

  if ($arResult[$index]["LINK"] <> "" && $index != $itemSize - 1) {
    $strReturn .= '<li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem">';
    $strReturn .= '<a itemprop="item" href="' . $arResult[$index]["LINK"] . '" title="' . $title . '"';
    if ($arSiblings) {
      $strReturn .= ' data-popup="^.breadcrumbs-content>.backnav.backnav_'. $index .'"';
      $strBacknav .= '<ul class="backnav backnav_' . $index . '">';
      $backnavIndex = 0;
      $j = 0;
      foreach ($arSiblings as $arSibling) {
        if($arSibling['LINK'] == $arResult[$index]['LINK']) {
          $backnavIndex = $j;
        }
        $strBacknav .= '<li><a href="' . $arSibling["LINK"] . '">' . $arSibling["NAME"] . '<i class="flaticon-arrow492 arrow arrow-up"></i></a></li>';
        ++$j;
      }
      $strBacknav .= '</ul>';
      $strReturn .=' data-backnav="' . $backnavIndex . '"';
    }
    $strReturn .= '><span itemprop="name">' . $title . '</span><i class="flaticon-arrow486 arrow arrow-down"></i></a><i class="separator flaticon-right20"></i>';
    $strReturn .= '<meta itemprop="position" content="' . ($index + 2) . '" />';
    $strReturn .= '</li> ';
} else {
    $strReturn .= '<li><span>' . $title . '</span></li>';
  }
}

$strReturn .= '</ul>' . $strBacknav .'</div>';

return $strReturn;

Answer 1

In the component settings, disable the output in the breadcrumbs of the element and add it there yourself via AddChainItem with the name you need.

Answer 2

Try replacing the line

$strBacknav .= '<li><a href="' . $arSibling["LINK"] . '">' . $arSibling["NAME"] . '<i class="flaticon-arrow492 arrow arrow-up"></i></a></li>';
        ++$j;

ON THE

$strBacknav .= '<li><a href="' . $arSibling["LINK"] . '">'.$title.'<i class="flaticon-arrow492 arrow arrow-up"></i></a></li>';
        ++$j;
