.InnerText returns undefined [duplicate]

I am trying to get the date from the element (class Pressroom-Item-date) using

document.getElementsByClassName('pressroom-item-date')

This returns undefined

<td><img width="16" height="1" src="/icons/ecblank.gif" border="0" alt=""><font size="2" face="Arial"></font></td>
<td style="min-width:80px ; border-bottom: 1px solid #DDD; padding: 10px; float:none;" class="pressroom-item-date">10/ 19/2020</td>
<td><font size="2" face="Arial"></font></td>

Here is the website form which I am trying to get the dates: https://ifcextapps.ifc.org/ifcext/pressroom/ifcpressroom.nsf/MorePressReleases/?OpenView&Start=1&Count=25
