Question

我有XML文件，其中包含很多带有html标签的twit。在所有其他任务中，我需要用@emoji替换所有标签我写了以下代码：

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

这对线路来说非常有效。但是，当我尝试在整个文件的循环中执行它时，它不会进入此循环。这是代码：

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

我也试图用html解析器做同样的事情，但我无法将标签转换为字符串：

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

xml文件非常大，可以完整地发布它，但它看起来像这样：

感谢您的帮助！

在解析文件之前，你可以read对文件进行re.sub，然后使用 @emoji 替换 img ，然后解析它使用ET.fromstring。你可以实现这个

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)

现在数据将在<@emoji的所有位置包含<img。现在，您可以根据自己的意愿解析结果数据。

将所有<img/>标记替换为XML文件中的一个单词
