父母与子女正则表达式匹配

Regex has always been a weaker point for me, so I need some help.

I'm basically try to have opening and closing 'tags' with the same regex allowed on the inside of these tags.

So a tag may look like:
<: tagname("[capture1]","[capture2]","[capture3]") :>[inner code]<: endtagname :>

So one with child tags may be like:
<: tagname("[capture1]","[capture2]","[capture3]") :>This is a tag: <: tagname("[capture1]","[capture2]","[capture3]") :>[inner code]<: endtagname :> that was a tag<: endtagname :>

So I've tried a few regex codes, but cannot figure out how to get the parent tag not to end on the child tag.

So here is one of the regex expressions that I've tried:
<:[ ]?date[ ]?[(][ ]?'"['"],[ ]?'"['"],[ ]?'"['"][)][ ]?:>([\s\S\t]*)<:[ ]?enddate[ ]?:>

This works for single level tags, but not for parent/child tags.

Any help is appreciated.

    As it was said in comment, build your parser. Here you've got examples (next answer), and some more resources: https://stackoverflow.com/a/8422952/6107031
