I would like to find the first occurrence of a string, after a certain other string, and between a certain pattern. The documents that I am parsing are not xml, but have similar rules of start/end. and example of what I would be looking at:
我想找到第一次出现的字符串，在某个其他字符串之后，以及某个模式之间。我正在解析的文档不是xml，但具有类似的开始/结束规则。以及我将要看的内容的例子：
...b.filext", "{xxxxx-xxx-xxx-xxx-xxxxxxxxxxx}"
and I am trying to get the string between { and }, right after an occurrence of a vcxproj, every time it happens in the document. I tried the following, but I get a list of None:
并且我试图在vcxproj发生之后立即在{和}之间获取字符串，每次它都发生在文档中。我尝试了以下内容，但是我得到了一个无列表：
my_list=[]
for line in text.split('.vcxproj'):
if '{' in line:
my_list.append(re.match( r"(?<=\{)(.*?)(?=\})", line))
I have tried to alter my expression but no success. Help ? Thank you.
我试图改变我的表达但没有成功。帮帮我 ？谢谢。

re.match matches only at the beginning of the string. Try re.search. Alternatively, replace the loop with re.findall.
re.match仅匹配字符串的开头。尝试re.search。或者，用re.findall替换循环。
