python multiline group regex

I'm trying to extract the mpath name "DS4800_VG_STAGE*" and the number of online paths from the output of multipath -ll.

DS4800_VG_STAGE_2 (3600a0b80004710ce00001ce24e08ce1c) dm-6 IBM,1815 FAStT

[size=241G][features=1 queue_i开发者_StackOverflow社区f_no_path][hwhandler=1 rdac][rw]

\_ round-robin 0 [prio=100][active]

\_ 1:0:1:5 sdc 8:32 [active][ready]

\_ round-robin 0 [prio=0][enabled]

\_ 2:0:1:5 sdf 8:80 [active][ghost]

DS4800_VG_STAGE_1 (3600a0b80004706be00001ece4e08ca4f) dm-8 IBM,1815 FAStT

[size=24112G][features=1 queue_if_no_path][hwhandler=1 rdac][rw]

\_ round-robin 0 [prio=100][active]

\_ 1:0:1:5 sdc 8:32 [active][ready]

\_ round-robin 0 [prio=0][enabled]

\_ 2:0:1:5 sdf 8:80 [active][ghost]

I've managed to extract the path name but am struggling with collecting the rest of the multiline output into a single group so I can process how many paths are on-line in group2.

^(\w+\s+).+?$$((?:[^\\\\]+\n+)+)

Match1:

Group 1 = "DS4800_VG_STAGE_2"

Group 2 = "[size=241G][features=1 queue_if_no_path][hwhandler=1 rdac][rw]"

Match2:

Group 1 = "DS4800_VG_STAGE_1"

Group 2 = "[size=24112G][features=1 queue_if_no_path][hwhandler=1 rdac][rw]"

Any help would be really appreciated.

Thanks in advance

Try using this instead:

^(\w+\s+).+?$$\n((?:.+?\n+)+)

I think in your expression you are using [^\\] which is preventing any line with backslash from being caught in the expression. But every line (following the first two "header lines") starts with a backslash.
