How to replace a number of string with incremental count in python

I have some HTML code (for display in a browser) in a string which contains any number of svg images such as:

<table>
  <tr>
    <td><img src="http://localhost/images/Store.Tools.svg"></td>
    <td><img src="http://localhost/images/Store.Diapers.svg"></td>
  </tr>
</table>

I would like to find all HTML links and replace them to the following (in order to attach them as email):

<table>
  <tr>
    <td><cid:image1></td><td><cid:image2></td>
  </tr>
</table>

SVG filenames can have any arbitrary number of dots, chars, and numbers.

What's the best way to do this in python?

I'd use an HTML Parser to find all img tags and replace them.

Example using BeautifulSoup and it's replace_with():

from bs4 import BeautifulSoup

data = """
<table><tr>
<td><img src="http://localhost/images/Store.Tools.svg"></td>
<td><img src="http://localhost/images/Store.Diapers.svg"></td>
</tr></table>
"""

soup = BeautifulSoup(data, 'html.parser')
for index, image in enumerate(soup.find_all('img'), start=1):
    tag = soup.new_tag('img', src='cid:image{}'.format(index))
    image.replace_with(tag)

print soup.prettify()

Prints:

<table>
 <tr>
  <td>
   <img src="cid:image1"/>
  </td>
  <td>
   <img src="cid:image2"/>
  </td>
 </tr>
</table>
