我想在 Python 中使用 lxml.etree 解析一个巨大的 xml (>200MB)。我尝试使用 etree.parse 加载 XML 文件，但由于文件大小，这不起作用:
etree.parse('file.xml')Traceback (most recent call last):

lxml.etree.XMLSyntaxError: Excessive depth in document: 256 use XML_PARSE_HUGE option, line 1276, column 7
因为我想使用 xpath 表达式，所以我必须先解析文件。因此，我该如何解析 XML 文件？如何使用 XML_PARSE_HUGE 连接到 lxml.etree？
谢谢!
最佳答案
尝试创建自定义 XMLParser 实例:
from lxml.etree import XMLParser, parse
p = XMLParser(huge_tree=True)
tree = parse('file.xml', parser=p)
关于python - 将 python lxml.etree 用于巨大的 XML 文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11850345/
