存在时，Beautifulsoup不匹配文本

Question

x = '<td class="greymeta">Posted Date:<br/> </td>'

parse = BeautifulSoup(x,"lxml")

parse.find("td",text=re.compile(r"^Posted Date:")) # doesn't return anything

如果<br/>代码中没有<td>：

x = '<td class="greymeta">Posted Date: </td>' 
parse.find("td",text=re.compile(r"^Posted Date:")) # returns output correcly
