在python3中转义XML字符串的未转义数据-EscapeunescapeddataofXMLstringinpython3

I want to escape the unescaped data inside a xml string e.g.

我想在xml字符串中转义未转义的数据。

string = "I want to escape these >, "

to

来

"I want to escape these >, "

• Now, I definitely can't use any xml parsing libraries like xml.dom.minidom or xml.etree because the data is unescaped & will give error
• 现在，我肯定不能使用任何xml解析库，比如xml.dom。minidom或xml。etree因为数据是不可转义的，会出现错误

• In regex, I figure out way to match & get start and end positions of data substing

  在regex中，我找到了匹配和获取数据删除的起始和结束位置的方法

  exp = re.search(">.+?

• But in re.search, I can't match the exact xml format

  但是在re.search中，我不能匹配确切的xml格式

• If I use re.findall I can't get positions of the substrings found
• 如果我使用re.findall，我无法获得找到的子字符串的位置
• I could always find positions of found substring by index but that won't be efficient, I want a simple but efficent solution
• 我总是可以通过索引找到找到子串的位置，但这不是有效的，我想要一个简单但有效的解决方案。
• BeautifulSoup solutions are welcomed but I wish there was some more beautiful way to do it with python's basic libraries
• 我们欢迎漂亮的解决方案，但是我希望有更漂亮的方法来使用python的基本库

>>> oldString = 'I want to escape these >, '
>>> newString = re.sub(r"()(.*?)", lambda m: m.group(1) + cgi.escape(m.group(2)) + "", oldString)
>>> print newString
I want to escape these >,
