==== Example ====

Replace from <wrap cmd>(?! )([\w -]+ )%"PRIu64" packet%s</wrap> to <wrap cmd>%"PRIu64" $1 packet%s</wrap>

**Before replacement**
<codeprism lang=c>
	dump("Transmit %"PRIu64" packet%s, %"PRIu64" byte%s\n"
		"%"PRIu64" unicast packet%s, %"PRIu64" multicast packet%s, "
		"broadcast %"PRIu64" packet%s\n"
		"good multicast %"PRIu64" packet%s, good broadcast %"PRIu64" packet%s\n"
		"64B %"PRIu64" packet%s, 65-127B %"PRIu64" packet%s\n"
		"128-255B %"PRIu64" packet%s, 256-511B %"PRIu64" packet%s\n"
		"512-1023B  %"PRIu64" packet%s, 1024B- %"PRIu64" packet%s\n",
</codeprism>

**After replacement**
<codeprism lang=c>
	dump("%"PRIu64" Transmit  packet%s, %"PRIu64" byte%s\n"
		"%"PRIu64" unicast packet%s, %"PRIu64" multicast packet%s, "
		"%"PRIu64" broadcast  packet%s\n"
		"%"PRIu64" good multicast  packet%s, %"PRIu64" good broadcast  packet%s\n"
		"%"PRIu64" 64B  packet%s, %"PRIu64" 65-127B  packet%s\n"
		"%"PRIu64" 128-255B  packet%s, %"PRIu64" 256-511B  packet%s\n"
		"%"PRIu64" 512-1023B   packet%s, %"PRIu64" 1024B-  packet%s\n",
