Re: XML dictionary parsing with flex/bison

[Hadriel Kaplan <HKaplan () acmepacket com>]

Afaik, libxml2 is under the MIT license which is not only usable in GPL, but also the same license Lua uses which 
Wireshark clearly has accepted, fwiw.  I thought I saw a libxml dependency, but obviously I'm wrong and I'm not going 
to add yet another library dependency, that's for sure. (wireshark has plenty as is :)

Isn't the lowest level Glib now 2.4?  If so, I can probably make do with the basic glib xml parsing abilities and avoid 
the newer functions added in 2.16/2.18.
