我想使用Python中的解析一个超过200MB的大型XML文件。我尝试使用加载XML文件,但由于文件大小,这并不起作用:
etree.parse('file.xml')Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "lxml.etree.pyx", line 2706, in lxml.etree.parse (src/lxml/lxml.etree.c:49958)

lxml.etree.XMLSyntaxError: Excessive depth in document: 256 use XML_PARSE_HUGE option, line 1276, column 7
因为我想要使用xpath表达式,所以我必须先解析文件。那么我该如何解析XML文件呢?我如何在使用时将XML_PARSE_HUGE
连接起来?
谢谢!
