Reading a Regex pattern

I did go through them but they don't really give me what I want. I'll show you my code and output. I can get what I want, I'll show you a code for that too, but I'm looking for a better way to do it, I think there is.

First code:

from bs4 import BeautifulSoup

html = '''ZZ~<ResponseCode>NoError</ResponseCode><Items><Message xmlns="http://schemas.micros~<?xml version="1.0" encoding="UTF-8"?><GetItemResponse xmlns="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns~[EXTERNAL] FW: Notification of Creation of SR: 0023TKLB: Reinstate Policy, PolicyNumber - 63321045153, Policyholder - VAN ECK M EN JF VAN ECK BOERDERY CRM:0912353

<body>
  <div id='images'>
    <a href='image1.html'>Name: My image 1 <br /><img src='image1_thumb.jpg' /></a>
    <a href='image2.html'>Name: My image 2 <br /><img src='image2_thumb.jpg' /></a>
    <a href='image3.html'>Name: My image 3 <br /><img src='image3_thumb.jpg' /></a>
  </div>
</body>
'''
soup = BeautifulSoup(html, 'html.parser')
soup = BeautifulSoup(html, 'lxml')
text = soup.text.strip()
print(text)

Output:

Output:ZZ~NoError

Name: My image 1 
Name: My image 2 
Name: My image 3

If you can see there there, this code returns the Header details as well. to remove the Header, this is what I do.

soup = BeautifulSoup(html, 'lxml')
text = soup.text.strip().split('\n-->')[1].strip()
print(text)

my output:

Output:Name: My image 1 
Name: My image 2 
Name: My image 3

So, I was wondering that I could get something that will remove the header for me.

You think of this in wrong way as in remove stuff.
A web-page can have 1000 of lines,so you get stuff needed with parser and leave rest.
Not remove all unwanted stuff which can be a lot.

So to get image info in code over.

>>> img_tag = soup.find('div', id='images')
>>> img_tag
<div id="images">
<a href="image1.html">Name: My image 1 <br/><img src="image1_thumb.jpg"/></a>
<a href="image2.html">Name: My image 2 <br/><img src="image2_thumb.jpg"/></a>
<a href="image3.html">Name: My image 3 <br/><img src="image3_thumb.jpg"/></a>
</div>
>>> 
>>> for img in img_tag.find_all('a'):
...     print(img.get('href'))
...     
image1.html
image2.html
image3.html
>>> for img in img_tag.find_all('img'):
...     print(img.get('src'))     
...     
image1_thumb.jpg
image2_thumb.jpg
image3_thumb.jpg
