Interesting approach! I was thinking of something schema-independant
though. I've got it working now, there's just one aggrivating bit of C code
that i have to do to translate between printf formatting codes and C
datatypes (you'd figure something like this would be part of the libc
core...)
#define DATA2XML(s,t) if(!strcmp(description.format, s)) {
sprintf((char*)__buffer, description.format, *((t*)data)); }
xmlNodePtr bt_data2xml(xmlNodePtr parent, bt_xml_node description, void*
data) {
if(!strcmp(description.format, "%s")) {
strcpy((char*)__buffer, (char*)data);
}
else DATA2XML("%llu", u_int64_t)
else DATA2XML("%lu", time_t)
else DATA2XML("%u", u_int32_t)
else {
__buffer[0] = 0;
fprintf(stderr, "Warning: %s is null: unknown format '%s'\n",
description.name, description.format);
}
return xmlNewTextChild(parent, NULL, description.name, __buffer);
}
Maybe one day I'll figure out a way to get rid of that, but it works
for now. :-)
