Q:

Replace all  tags with one word in XML file

I have XML file, that consits of many twit with html tags in them. 
Among all the other tasks, I need to replace all  tags with a word @emoji
I have written the following code:
for word in re.findall(r"&lt;img[\w\W]+?/&gt;",line):
    print word
    line = line.replace(word,'@emoji')

It is perfectly working for the line. 
However, when I try to do it in the loop for the whole file, it is not going inside this loop. Here is the code:
import re
import xml.etree.ElementTree as ET #xml lib
filename = 'da0d0e3527b931bb0bc6f5435003ea2a.xml'
tree = ET.parse(filename)
root = tree.getroot()
twits = []
for child in root:
   for grandchild in child:
        twits.append(grandchild.text)
for line in twits:
    for word in re.findall(r"&lt;img[\w\W]+?&gt;",line):
        line = line.replace(word,'@img')
    print line

I was also trying to do the same with html parser, but I can't turn tag to string:
imgs = soup.find_all('img')
for img in imgs:
    print img
    emo = str(img)
    twit.replace(emo,'@emoji')

The xml file it very big to publish it completly, but it looks like this:

Thank you for your help!

A:

Before parsing the file you can read it and can do a re.sub upon the data to replace img with @emoji and then parse it using ET.fromstring. you can achieve this like
from re import sub
import xml.etree.ElementTree as ET #xml lib
data = 'da0d0e3527b931bb0bc6f5435003ea2a.xml'
data = re.sub(r"&lt;img[\w\W]","&lt;@emoji",open(data).read())
tree = ET.fromstring(data)

now data will contain &lt;@emoji in all places of &lt;img. now you can parse the resulting data as per your wish.
