How to find multiline text between curly braces?

Question

I have next input string:

ANIM "_NAME_KEY_" // Index = 26, AFrames = 1
    {
        0x301C
        AF  0x201C  1   0   0   FREE_ROTATE 0   FREE_SCALE_XY 100 100
    }

How can i get whole string between two curly braces, just having _NAME_KEY_ ?

Answer 1

Use the option re.MULTILINE as a second argument to your re.compile/etc. call.

I would propose this regex: _NAME_KEY_[^{]*+\{([^}]+)\}

Explanation:

_NAME_KEY_: match "_NAME_KEY_"

[^{]*: match as many non-{-characters as possible (greedy)

\{: match a { character

([^}]+): match (and capture) non-}-characters (greedy)

\}: match one } character

Answer 2

re.findall(r'(?<={)[^}]*',str)

E.g.

In [5]: x="""ANIM "_NAME_KEY_" // Index = 26, AFrames = 1
    {
        0x301C
        AF  0x201C  1   0   0   FREE_ROTATE 0   FREE_SCALE_XY 100 100
    }"""

In [6]: import re

In [7]: re.findall(r'(?<={)[^}]*',x)
Out[7]: ['\n        0x301C\n        AF  0x201C  1   0   0   FREE_ROTATE 0   FREE_SCALE_XY 100 100\n    ']
