WBXML

Wireless Binary XML is one of the scourges of dealing with handset-oriented implementations of SyncML. Like pretty much any other binary XML variant (such as binary WML) it is a bad idea.

Nevertheless, it is a bad idea with a few elegant workarounds (the best of which is still not using it in the first place).

• Python bindings for libwbxml.
• XML Watch: WBXML and basic SyncML server requirements - short article, but to the point and with links to several other useful resources.
• libwbxml - GPL, but has recently announced commercial sponsoring.
• Sybyx - a C++-based streaming parser
• kXML - a Java XML toolkit for embedded devices with WBXML support.
• Ethereal has a dissector for it, so you can trace requests on the wire.
