应用错误收集

我需要解析两组中的以下几行：
第1组：ADJ-1-37-10
第2组：3.00（如果没有SPANLOSSMARGIN标签那么它应该是空的）

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。但由于该行不包含SPANLOSSMARGIN标记，因此它与ADJ-1-37-16不匹配。我的要求是当有ADJ-X-XX-XX标签（不管是否存在其他标签）时，第1组应该返回它，当有SPANLOSSMARGIN标签时，第2组应该返回它;但只有当没有SPANLOSSMARGIN标记时，Group 2才会返回空。我怎样才能做到这一点？

"ADJ-1-2-5::FIBERTYPE=NDSF,OSCSPANLOSS=16.00,TARGSPANLOSS=16.00,MINSPANLOSS=0.00,SPANLOSSMARGIN=3.00"
   "ADJ-1-13-5::FIBERTYPE=NDSF,OSCSPANLOSS=16.00,TARGSPANLOSS=16.00,MINSPANLOSS=0.00,SPANLOSSMARGIN=3.00"
;
   "ADJ-1-37-2::FIBERTYPE=UNKNOWN,TARGSPANLOSS=0.00,MINSPANLOSS=0.00,SPANLOSSMARGIN=3.00,SPANLOSSSOURCE=UNKNOWN,BUNDLEID=\"\",LINEIN=\"\",LINEOUT=\"\",CRSIN=\"\",CRSOUT=\"\""
