Java-XML解析器性能:Sun Java Streaming XML解析器(SJSXP)与Woodstox [英] Java - XML parser performance : Sun Java Streaming XML Parser (SJSXP) vs Woodstox

问题描述

我正在寻找最新的，内存效率高且高性能的Java XML解析API. 我需要解析3 MB到5 MB的XML文件.

I am looking for latest, memory efficient and high-performance java XML parsing API. I need to parse 3 MB to 5 MB XML files.

我在Google上进行了搜索，并了解了Sun Java Streaming XML Parser(SJSXP)，Woodstox的速度比DOM& SAX.两者都使用StAX API. *这些技术不支持模式验证.

I did google on this and come to know about Sun Java Streaming XML Parser (SJSXP) and Woodstox is much faster than DOM & SAX. Both are using StAX API. *schema validation is not supported by these technologies.

Aalto XML处理器还实现了StAX API.

Aalto XML processor is also implements StAX API.

我还没有找到有关这些技术性能的具体发现.

I have not found concrete findings on performance on these technologies.

在内存高效，高性能和易用性方面，哪一个是最佳选择?

Which one will be best in context of memory efficient, high-performance and ease of use ?

关于性能:SJSXP是最慢的；它只是Xerces的内部重新包装，包装在Stax API中.这对性能有一些负面影响(因为它不是真正为拉解析设计的). Woodstox更快一些.小文档和书写的速度更快，解析较长文档时的差异也较小.

As to performance: SJSXP is the slowest; it's just a repackage internals of Xerces, wrapped in Stax API. This has some negative effects on performance (since it's not really designed for pull parsing). Woodstox is bit faster; much faster for small documents and writing, less difference when parsing longer documents.

而Aalto则是这三者中最快的，尤其是对于解析而言.通常比Woodstox或SJSXP快50％-100％.缺点之一是它不处理DTD(因此不处理外部实体；它处理预定义和字符实体).

And Aalto is by far fastest of the three, especially for parsing. It is commonly 50% - 100% faster than either Woodstox or SJSXP. One downside is that it does not handle DTDs (and thereby not external entities; it handles pre-defined and character entities).
