python - 如何解析这种格式(Praat TextGrid)

Question

TextGrid 是 Praat 程序使用的“分割”文件。我想编写一个解析器来验证数据。我的问题是:

您将如何为这种格式编写解析器？逐行阅读还是其他？这是已知格式吗？

File type = "ooTextFile"
Object class = "TextGrid"

xmin = 0 
xmax = 93.0538775510204 
tiers? <exists> 
size = 3 

item []: 
    item [1]:
        class = "IntervalTier" 
        name = "diph" 
        xmin = 0 
        xmax = 93.0538775510204 
        intervals: size = 65 
        intervals [1]:
            xmin = 0 
            xmax = 1.300090702947846 
            text = "" 
        intervals [2]:
            xmin = 1.300090702947846 
            xmax = 1.5300845864661654 
            text = "ey_s" 
        intervals [3]:
            xmin = 1.5300845864661654 
            xmax = 3.4648692624493815 
            text = "" 

(然后重复到 EOF，间隔 [4....n])

TextGrid 解析器已经存在，它是 NLTK 工具包的一部分。 Python 文件在这里:
