Vik's XPath Presentation
SAX
- No formal specification
- Requires less memory, because the whole document is not stored in memory
- Better for larger files
- some processing and validation requires the whole file anyway, which DOM already does (XSLT, XPath)
DOM
- Used by JavaScript to dynamically change a web page
NQXML
- Not Quite XML
- Only real competition for REXML
- Home page says to use REXML now, as it is included with Ruby
Flat Filer
Andy Libby from Tangeis LLC was kind enough to give a talk at the most recent cprb meeting on a gem he wrote called FlatFiler.
The gem is released under the MIT license and available via github.
The purpose of the gem is to consume and produce fixed width data files from disparate customers. It also contains ways to use it with ActiveRecord.
The presentation can be found here.
