用XML文件中的一個單詞替換所有<img>標記

我有XML文件，它們中包含許多twit和html標記。在所有其他任務，我需要@emoji 我寫了下面的代碼字代替所有標籤：用XML文件中的一個單詞替換所有<img>標記

for word in re.findall(r"&lt;img[\w\W]+?/&gt;",line): 
    print word 
    line = line.replace(word,'@emoji')

這是完全爲線工作。但是，當我嘗試在整個文件的循環中執行時，它不會進入此循環。下面是代碼：

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

我也試着用HTML解析器一樣，但我不能把標籤字符串：

imgs = soup.find_all('img') 
for img in imgs: 
    print img 
    emo = str(img) 
    twit.replace(emo,'@emoji')

XML文件非常大，它發佈但它看起來像這樣：

你有沒有試過're.sub（pattern，'@emoji'，line）'但呢？這會使循環過時。 – Boldewyn

@Boldewyn剛剛嘗試過，仍然不工作:( –

爲什麼不只是使用'sed'？ –

解析可以read，並可以做文件之前re.sub在該數據與@emoji更換IMG，然後使用ET.fromstring解析它。你可以做到這一點像

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)

現在數據將包含<@emoji在<img所有地方。現在你可以根據你的意願解析結果數據。
