I have started writing this post as a sidebar in comparing the parsers in my benchmarks. I will post what I know, and add more to it as I am informed by the community. Consider this a living post. Where something is just a fact, I list it as a Pro, such as language developed.
| Product |
Pros |
Cons |
| Tango PullParser (pull) |
- Written in the D programming language
- Tango devs are very aware of cost of allocation, and try to avoid it as often as possible.
- Extremely fast, extremely memory efficient
|
- Beta level code
- Interfaces may change, since Tango is not yet 1.0
- NOT W3C XML compliant (ignores DOCTYPE, etc)
|
| Tango SaxParser (SAX) |
- Written in the D programming language, on top of Tango’s PullParser.
- Straight port of Java SAX code, with a small amount of D flavor
- Useful for porting existing SAX-based code
|
- Beta level code
- Interfaces may change, since Tango is not yet 1.0
- As shown in the benchmarks, virtual calls (SAX does a lot of them) cost quite dearly
- NOT W3C XML compliant
|
| Tango Document (DOM) |
- Written in the D programming language, and a DOM-style tree of xml to manipulate
- Faster than all non-tree code tested so far
- Not DOM compliant
- Integrated query language, inspired by XPath
|
- Beta level code
- Interfaces may change, since Tango is not yet 1.0
- Not DOM compliant
- NOT W3C XMLcompliant
|
| Phobos std.xml (DOM) |
- Written in the D programming language
- Shipped in D 2.0’s standard library
- DOM-style tree object model
- Not DOM compliant
|
- Not DOM compliant
- Requires previous knowledge of the structure of the xml being parsed. Cannot parse arbitrary XML
- NOT W3C compliant
|
| RapidXml (DOM) |
- Written in C++, with ultimate performance in mind
- Highly configurable, use only the featureset you need.
- Not DOM compliant
|
- Not DOM compliant
- Not W3C XML compliant (ignores DOCTYPE)
|
| libxml2 (SAX) |
- Written in C
- extremely robust - passes all 1800 tests from the OASIS XML Tests Suite
|
|
| VTD-XML (DOM) |
- Written in Java, also availabe in C, C#
- Indexes the XML for super fast querying
- XPath Support
|
|
| Java SAX (SAX) |
|
|
| Java DOM (DOM) |
- Written in Java
- W3C DOM compliant
- W3C XML compliant
- XPath support
|
|
| Java StaX parsers (pull)(includes Aalto, Woodstox, and javolution) |
|
