是否有适用于SAX型号的XPath处理器？ [英] Is there any XPath processor for SAX model?

问题描述

我正在寻找一个XPath评估器，它不会重建整个DOM文档来查找文档的节点：实际上该对象是使用SAX模型管理大量XML数据（理想情况下超过2Gb），这对内存管理非常有用，并且可以搜索节点。

I'm looking for an XPath evaluator that doesn't rebuild the whole DOM document to look for the nodes of a document: actually the object is to manage a large amount of XML data (ideally over 2Gb) with SAX model, which is very good for memory management, and give the possibility to search for nodes.

谢谢大家的支持！

对于那些说不可能的人：我最近在问到这个问题之后，发现了一个名为saxpath的项目（ http://www.saxpath.org/ ），但我找不到任何实施项目。

For all those who say it's not possible: I recently, after asked the question, found a project named "saxpath" (http://www.saxpath.org/), but I can't find any implementing project.

推荐答案

我当前的列表（根据网络搜索结果和其他答案编译）是：

My current list (compiled from web search results and the other answers) is:

• http://code.google.com/p/xpath4sax/


• http://spex.sourceforge.net/


• https://github.com/santhosh-tekuri/jlibs/wiki/XMLDog （还包含一个表演图表）


• http：//www.cs.umd .edu / projects / xsq / （大学项目，10年后死亡，GPL）


• MIT许可方法 http://softwareengineeringcorner.blogspot.com/2012/01/conveniently-processing-large-xml-files.html


• 支持快速XPath的其他解析器/内存模型：
  
  
  
  
  • http://vtd-xml.sourceforge.net/ （世界上最快的XPath 1.0实现。）
  
  
  • http://jaxen.codehaus.org/ （包含 http://www.saxpath.org/ ）
  
  
  • http：// www .saxonica.com / documentation / sourcedocs / streaming / streamable-xpath.html
  
  
  • http://code.google.com/p/xpath4sax/
  • http://spex.sourceforge.net/
  • https://github.com/santhosh-tekuri/jlibs/wiki/XMLDog (also contains a performance chart)
  • http://www.cs.umd.edu/projects/xsq/ (uniersity project, dead since 10 years, GPL)
  • MIT-Licensed approach http://softwareengineeringcorner.blogspot.com/2012/01/conveniently-processing-large-xml-files.html
  • Other parsers/memory models supporting fast XPath:
    • http://vtd-xml.sourceforge.net/ ("The world's fastest XPath 1.0 implementation.")
    • http://jaxen.codehaus.org/ (contains http://www.saxpath.org/)
    • http://www.saxonica.com/documentation/sourcedocs/streaming/streamable-xpath.html

    下一步是使用XMLDog的示例并比较所有这些方法的性能。然后，测试用例应扩展到支持的XPath表达式。

    The next step is to use the examples of XMLDog and compare the performance of all these approaches. Then, the test cases should be extended to the supported XPath expressions.
