Retrieve 'tr' by text of children - python-3.x

Question

I want to select a tr by the text it contains, including the text of the children.
My html is as follows:
<table>
<tbody>
<tr>
<td>
<span id="ctl00_ContentPlaceHolder1_GridView1_ctl21_Label4">Sanskrit</span>
</td>
<td>
<span id="ctl00_ContentPlaceHolder1_GridView1_ctl21_Label2">0655-0700 </span>
</td>
<td>
<a id="ctl00_ContentPlaceHolder1_GridView1_ctl21_LinkButtonDownloadPdf" href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$GridView1$ctl21$LinkButtonDownloadPdf','')" style="color: Navy;
font-weight: bold;">Download</a>
</td>
<td>
<span id="ctl00_ContentPlaceHolder1_GridView1_ctl21_Label3">24 October</span>
</td>
</tr>
<tr>
<td>
<span id="ctl00_ContentPlaceHolder1_GridView1_ctl22_Label4">Sanskrit</span>
</td>
<td>
<span id="ctl00_ContentPlaceHolder1_GridView1_ctl22_Label2">1810-1815 </span>
</td>
<td>
<a id="ctl00_ContentPlaceHolder1_GridView1_ctl22_LinkButtonDownloadPdf" href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$GridView1$ctl22$LinkButtonDownloadPdf','')" style="color: Navy;
font-weight: bold;">Download</a>
</td>
<td>
<span id="ctl00_ContentPlaceHolder1_GridView1_ctl22_Label3">23 October</span>
</td>
</tr>
</tbody>
</table>
I load it thus _soup = soup(html, "html.parser").
If i run _soup.find("span", text="Sanskrit").parent.parent.text then I get the result '\n\nSanskrit\n\n\n0655-0700 \n\n\nDownload\n\n\n24 October\n\n'
but if i run print(_soup.find("tr", text='\n\nSanskrit\n\n\n0655-0700 \n\n\nDownload\n\n\n24 October\n\n'))
i get None

Answer 1

Issue here is that text needs an exact match - You could regex or use css selectors and :-soup-contains():
soup.select('tr:has(:-soup-contains("Sanskrit"))')
or based on comment, check if your text is in <tr>s text:
for row in soup.select('tr'):
if '\n\nSanskrit\n\n\n0655-0700 \n\n\nDownload\n\n\n24 October\n\n' in row.text:
print(row)
