How to get content between two DIVs with jQuery

It is very simple to get content inside DIVs or inside others tags with jQuery, however, the complexity come when we try to get a particular text between two HTML tags, here is an example of problem:

I have .parent with many DIVs inside, I’m just interested by getting "Paragraph 1", "Paragraph 2" and “Paragraph 3" content.

HTML code:

<div class="parent">
    <div class="first">first</div>
    <div class="child1">child1</div>

    Paragraph 1
    <br>
    Paragraph 2
    <br/>       
    Paragraph 3

    <div class="child2">child2</div>
    <div class="child3">child3</div>

        Last Content
        <br/>
        Last Content 2
        <br/>
        Last Content 3

    <div class="last">last</div>
</div>

jQUERY solution:

var appendSt = $('.child3').after('code:'),
    content  = $('.parent').clone().children().remove().end().text(),
    reg      = content.replace(/code:([^xyz]+)/, '');
alert(reg);
