Just a wild guess:
maybe it is easier to use the `-json` output and parse it (here: quick
Sentinel-2 example, not very elegant):

gdalinfo S2A_MSIL2A_20190912T025541_N0213_R032_T48MYT_20190912T065935.zip
-json | jq ".metadata" | jq ".SUBDATASETS" | jq ".SUBDATASET_2_NAME"
"SENTINEL2_L2A:/vsizip/S2A_MSIL2A_20190912T025541_N0213_R032_T48MYT_20190912T065935.zip/S2A_MSIL2A_20190912T025541_N0213_R032_T48MYT_20190912T065935.SAFE/MTD_MSIL2A.xml:20m:EPSG_32748"
