Jython 和 SAX 解析器:允许的实体不超过 64000 个?
我在 Jython 中对大型 XML 文件 (800 MB) 中的 xml.sax
解析器进行了简单测试,并遇到了以下错误:
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“应用程序强加的限制”有什么问题吗?我怎样才能覆盖它?
我尝试使用 Java XML 库 nu.xom
并遇到了相同的错误。
I've done a simple test of the xml.sax
parser in Jython on a large XML file (800 MB) and encountered the following error:
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.
What is the matter with this "limit imposed by the application" and how can I override it?
I have tried to use the Java XML library nu.xom
and ran into the same error.

尝试将
entityExpansionLimit
属性设置为高于 64000 的值。请参阅 http://download.oracle.com/javase/1.5.0/docs/guide/xml/jaxp/JAXP-Compatibility_150.html#JAXP_security。Try setting the
entityExpansionLimit
property to a higher value than 64000. See http://download.oracle.com/javase/1.5.0/docs/guide/xml/jaxp/JAXP-Compatibility_150.html#JAXP_security.
