Selenium - how to get element and its subelements text

Short version: I can get the chat message (using selenium's By.xpath in java) but I want to include smiles into proper places.

Longer version: Hello, I've been tackling this interesting issue where I need to parse a chat message from the web browser and recreate it using java and selenium. I got no problem parsing the text of the message but I want to parse it with it's subelements (smile icons) as well. Is there any good approach to this except for manual source code parsing?

Here's a code for a single message that I'm able to access:

<div class="chat_msg chat_msg_caller ">
    <div class="chat_msg_head">
        <span class="chat_msg_author">
            SomeAuthor
        </span>
        <span class="chat_msg_date">
           SomeDate
        </span>
    </div>
    <div class="chat_msg_body message_text">
        SomeMessageText
        <span class="sml-icon biggrin">
            <span>
                :D
            </span>
        </span>
        SomeOtherText
        <span class="sml-icon biggrin">
            <span>
                :D
            </span>
        </span>
    </div>
</div>

Here's an example of how I'm getting the chat message text:

String msgTxt = we.findElement(By.xpath("//div[@id='messages_body']/div[" + (i + 1) + "]/div[@class='chat_msg_body message_text']")).getText();

My result: SomeMessageText SomeOtherText The result I want: SomeMessageText :D SomeOtherText :D
