• 1 button would be outside li tag which i haven't mentioned but need to change text on html button click. – SanketS Commented Mar 10, 2016 at 9:17
• 1 Are there multiple li elements? If so, how do you determine which li should be affected from the button click? – Rory McCrossan Commented Mar 10, 2016 at 9:18
• @RoryMcCrossan, I can determine which li will be affected but i only need to change text of current li tag. – SanketS Commented Mar 10, 2016 at 9:28
• @SanketS but that's my point - how do you determine what the current li is? We need to see more of your code, both the HTML and your JS. – Rory McCrossan Commented Mar 10, 2016 at 9:29

Get the span inside the li then get the text node after to it and update the text

$('#change').click(function() {
  $('li.select2-selection__choice')
    // get the span inside, and use `[0]` to get dom object
    .find('span')[0]
    // get next node after span, which is text node
    .nextSibling
    // update the text content with new value
    .textContent = 'text';
})

<script src="https://ajax.googleapis./ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button id="change">Change Text</button>
<ul>
  <li ondblclick="editThisTag(this)" title="New Account0123" class="select2-selection__choice">
    <span class="select2-selection__choice__remove" role="presentation">×</span>
    Testing Text
  </li>
</ul>

Or following method using contents() , filter() and replaceWith()

$('#change').click(function() {
  $('li.select2-selection__choice')
    // get all nodes including text node and ment node
    .contents()
    // filter to get only text node and which is not empty
    .filter(function() {
      return this.nodeType === 3 && this.nodeValue.trim().length;
    })
    // replace it with new text
    .replaceWith('text');
})

<script src="https://ajax.googleapis./ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button id="change">Change Text</button>
<ul>
  <li ondblclick="editThisTag(this)" title="New Account0123" class="select2-selection__choice">
    <span class="select2-selection__choice__remove" role="presentation">×</span>
    Testing Text
  </li>
</ul>

Having a function to find the text you want to change.

jQuery("li").text(function () {
    return jQuery(this).text().replace("Testing Text", "hello world"); 
});

https://jsfiddle/o9va6mqe/

Working fiddle ^

Enclose with the tag the text you want to change so you can specify which part of li will be change. Do it like this.

$('button#changeText').click(function() {
  $('li.select2-selection__choice').find('font').html('HELLO WORLD');
});

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="changeText">Change Text</button>
<li title="New Account0123" class="select2-selection__choice">
  <span class="select2-selection__choice__remove" role="presentation">×</span>
  <font>Testing Text</font>
</li>
