如何自定义输出wp_NAV_MENU()

目前我正在使用此代码输出菜单显示：

<?php
wp_nav_menu(array(
    \'theme_location\' => \'songs-category\',
    \'container\' => false, 
    \'menu_id\' => \'nav\',
    \'menu_class\' => \'\',
    \'items_wrap\' => \'<ul id="nav"><li class="active"><a href="#" data-slug="4,5,6,7,8,9" class="xyz">All</a></li>%3$s</ul>\'
    ));

正在获取输出：

<ul id="nav">
    <li class="active"><a href="http://domain.com/" title="All">All</a></li>
    <li><a href="http://domain.com/category/category1/">category1</a></li>
    <li><a href="http://domain.com/category/category2/">category2</a></li>
    <li><a href="http://domain.com/category/category3/">category3</a></li>
    <li><a href="http://domain.com/category/category4/">category4</a></li>
    <li><a href="http://domain.com/category/category5/">category5</a></li>
    <li><a href="http://domain.com/category/category6/">category6</a></li>
    <li><a href="http://domain.com/category/category7/">category7</a></li>
    <li><a href="http://domain.com/category/category8/">category8</a></li>
    <li><a href="http://domain.com/category/category9/">category9</a></li>
</ul>

但需要这样的输出：

<ul id="nav">
  <li><a href="#" data-slug="4,5,6,7,8,9,10,11,12,13,14,15" class="xyz">All</a></li>     
  <li><a href="#" data-slug="10" class="xyz">category1</a></li>
  <li><a href="#" data-slug="12" class="xyz">category2</a></li>
  <li><a href="#" data-slug="15" class="xyz">category3</a></li>
  <li><a href="#" data-slug="9" class="xyz">category4</a></li>
  <li><a href="#" data-slug="4" class="xyz">category5</a></li>
  <li><a href="#" data-slug="11" class="xyz">category6</a></li>
  <li><a href="#" data-slug="13" class="xyz">category7</a></li>
  <li><a href="#" data-slug="8" class="xyz">category8</a></li>
  <li><a href="#" data-slug="7" class="xyz">category9</a></li>
</ul>

我不知道如何做到这一点。

// Get wordpress menu and do a custom output $getMenu = wp_get_nav_menu_items( \'menu1\'); // Where menu1 can be ID, slug or title foreach($getMenu as $item){ echo \'<li><a href="\' . $item->url . \'">\' . $item->title . \'</a></li>\'; }
