How to get only rely content(black color) and not included quote(blue color) content using Selenium and Python

Question

I want to know what to get some content not include quote content.

The following url is the target webpage:

https://forumd.hkgolden.com/view.aspx?type=BW&message=7219211

I must use a full xpath to get their content. I want to get black color content and I don't want to get blue content, but when I use the following code. I got blue and blank content together.

content = driver_blank.find_element_by_xpath('/html/body/form/div[5]/div/div/div[2]/div[1]/div[5]/table[8]/tbody/tr/td/table/tbody/tr/td[2]/table/tbody/tr[1]/td/div')
print(content.text)

The following is their html code:

<table width="100%" cellpadding="0" cellspacing="0" style="margin-bottom: 7px;">
    <tbody>
        <tr>
            <td align="left">
                <table class="repliers">
                    <tbody>
                        <tr hc7uwnfktbez9="" id="XoBTa" userid="461194" username="浅川梨奈">
