I've been looking into what xml parsing approach to use for my open source
Java GPS Access Library.
Currently I only output XML, so am just building it using brute-force Java code
without using any specific parser/toolkit. The issue becomes blurry now that I
am looking at reading in XML as well (validated by the GPSml schema).
Normally I would say that using SAX might be the best bet, since my library is
already event driven and the paradigms fit nicely.
JDOM is attractive because of it's javatized API, but it's not clear to me if
JDOM reads in the whole document structure or not when you read a
document, or does it just interact with SAX under the covers as you request
elements that are progressively deeper in the tree?
The thorny issue is that one of the key features of the GPS code base is that it
runs (more or less) unchanged on many platforms, including smaller PDA's
and embedded Java devices (like boards based on the aJile Java chip). That
means that total size of the application (including all jar files) is important, and
even more so, some standard API's (like many java.io classes) are not
available, which causes problems with SAX/JDOM.
Any advice on how to proceed? Since SAX and JDOM are open sourced, I'm
leaning towards using a stripped down version of these tools which specialized
IO classes added to support the embedded devices.
Thoughts?
Thx!
