You can use xsl:if or xsl:choose/xsl:when of course inside of the
function itself, as well as XPath

 B  if (expression) then expression else expression

instead.

It is not clear which values can be missing and how you want to complete
them.

As for other approaches, there is xsl:analyze-string and in XSLT 3/XPath
3.1 there is also the XPath analyze-string function you could try with a
pattern for the various groups of digits you expect, push the result
through a mode that adds the default data for missing groups and push
through another mode perhaps that outputs the attribute nodes.
