我需要在 2 组中解析以下行：
第 1 组：ADJ-1-37-10
第 2 组：3.00（如果没有 SPANLOSSMARGIN 标记，则应为空）
到目前为止，我使用"(ADJ-\d{1,3}-\d{1,3}-\d{1,3})::.*?SPANLOSSMARGIN=(\d{1,2}.\d{1,2}) 来解析以下行。但它与 ADJ-1-37-16 不匹配，因为该行不包含 SPANLOSSMARGIN 标记。我的要求是当有 ADJ-X-XX-XX 标签时（无论是否存在其他标签），那么第 1 组应该返回它，当有 SPANLOSSMARGIN 标签时，第 2 组应该返回它；但仅当没有 SPANLOSSMARGIN 标记时，第 2 组才应返回空。我怎样才能做到这一点？
