In engineering we use english decimal separator always, but it´s perfect 
both support.
I am using PCRE and works fine with this. You can combine XMLlib with pcre.
Internally in the gtktreeview for example we want see always dots.

In .NET this problem is solved thanks to globalization library, but in 
visual basic 6 this problem have a dificult solution. Many people in 
visual basic 6 change the windows unit system when the app begin and 
restart the initial configuration when the program end.

PCRE is use nowadays in GLIB i think, but it´s a PERL 5 regular 
expresion compatible library used in .NET, JAVA, python, php,...
I am building an intermediate  unit system for engineeres in Gobject and 
i hope publish this library soon.
With this system you always work in lineal measures in meters (double), 
and you can input others (inches, centimeters)

input system - intermediate system -out system

you can input in a entry for example (22m, 22 m, 220cm,...) and 
internally you have a double always in meters.
I have other system to angles, and so...
In a external file you have the units and the decimal separators amount.

for example in Spain you see:

23.345 m
45 g 34 c 34.456 cc

, but other could be:
23.2 m
45º 34' 23.23''

,

or

234.34564 in
2345 s (degree angular seconds)

It´s PCRE which process this text  (22in, 22 m 2º3'23.34'', 
35g23c34.45cc,...)

In KOMODO IDE you can create your expresion in a easy way ;-)

Pd:
I see  many engineeres fans here of GTK. We can  share many thinks...

Regards.
