javascript recursive iteration is returning entire parent div in the recursive iteration

I want to implement search functionality on my div whose html is as below :

<input type="search" id="mysearch" placeholder="Search here"     />
    <div  class="sken-cues-body" id="mydivbody">
         <div class="sken-cue-card" style="display: block;">
            <div class="salesken-flex salesken-flex-column">
                <div class="sken-cue-title">Welcome to My Customer!</div>
                <div class="sken-cue-text">
                    Want to help every sales agent like a <b>champion !</b>
                </div>
                <div class="">
                    <a type="button" href="https://salesken.ai/sign-in.html" class="sken-button-theme">START HERE</a>
                </div>
            </div>
        </div>  
        <div class="sken-cue-card salesken-flex"  style="display: block;">
            <div class="salesken-flex salesken-flex-column">
                <div class="sken-cue-time">2:16 pm</div>
                <div class="sken-cue-title">Talking Points</div>
                <div class="sken-cue-text" id="11">
                    <ul >
                        <li>Greet the customer</li>
                        <li>Ask if it is a good time to talk</li>
                        <li>Be polite &amp; courteous on the call</li>
                        <li>Listen carefully</li>
                        <li>Thank the customer for their time</li>
                    </ul>
                    <p></p>
                </div>
            </div>
        </div>
         <div class="sken-cue-card salesken-flex" style="display: block;">
            <div class="salesken-flex salesken-flex-column">
                <div class="sken-cue-time">2:16 pm</div>
                <div class="sken-cue-title"></div>
                <div class="sken-cue-text">
                    <p>

                        If the account has not been active for more than 90 days, it will be declared an NPA and that will lead to strident actions. Need to start&nbsp;paying the EMIs to avoid unnecessary legal hassles<br>
                        <br>
                    </p>

For implemention search functionality,i need to recursive iteration inside div with ID mydivbody. Below is javascript function for recursive iteration in div with ID mydivbody:

document.getElementById('mysearch').addEventListener('keyup',function(){
    var node = document.getElementById('mydivbody')
    allDescendants(node,this.value) 
});

function allDescendants (node) {
    for (var i = 0; i < node.children.length; i++) {
      var child = node.children[i];
      allDescendants(child);
         console.log(child)
      }

      //doSomethingToNode(child,search_value);
    }

But in this js function, i can see all child nodes where i am consoling the child along with entire parent div. for me node is getting duplicated. Please suggest how to fix this
