我做了一个简单的测试xml.saxJython 中的解析器在处理大型 XML 文件 (800 MB) 时遇到以下错误：
Traceback (most recent call last):
File "src/project/xmltools.py", line 92, in <module>
sys.exit(main())
File "src/project/xmltools.py", line 87, in main
parser.parse(open(argv[1], "r"))
File "/amd.home/home/user/workspace/jython-2.5.2/Lib/xml/sax/drivers2/drv_javasax.py", line 146, in parse
self._parser.parse(JyInputSourceWrapper(source))
File "/amd.home/home/user/workspace/jython-2.5.2/Lib/xml/sax/drivers2/drv_javasax.py", line 59, in fatalError
self._err_handler.fatalError(_wrap_sax_exception(exc))
File "/amd.home/home/user/workspace/jython-2.5.2/Lib/xml/sax/handler.py", line 38, in fatalError
raise exception
xml.sax._exceptions.SAXParseException: <unknown>:1:1: The parser has encountered more than "64,000" entity expansions in this document; this is the limit imposed by the application.
这个“应用程序施加的限制”有什么问题，我该如何覆盖它？
我尝试过使用 Java XML 库nu.xom并遇到了同样的错误。
尝试设置entityExpansionLimit财产价值高于 64000。参见http://download.oracle.com/javase/1.5.0/docs/guide/xml/jaxp/JAXP-Compatibility_150.html#JAXP_security http://download.oracle.com/javase/1.5.0/docs/guide/xml/jaxp/JAXP-Compatibility_150.html#JAXP_security.
