Appriciate all help I can get

Answer 1

Regular expressions cannot be used to parse HTML; HTML is not regular. Use a proper HTML parser library.

Answer 2

It depends on how regular the HTML text is. For example, given this table:

<table>
  <tr><td>1</td><td>Apple</td></tr>
  <tr><td>2</td><td>Ball</td></tr>
  <tr><td>3</td><td>Cookie</td></tr>
<table>

The following regex expression finds the IDs in the first column:

(?<=<tr><td>).*?(?=</td>)

Answer 3

If you run the page through an html-parser like BeautifulSoup, then you can prettify it so that this kind of regex has a chance. But if you are parsing the html anyway...
