Given the following text, what PCRE regular expression would you use to extract the parts marked in bold?
00:20314 lorem ipsum want this kryptonite 00:02314 quux padding dont want this 00:03124 foo neither this 00:01324 foo but we want this stalagmite 00:02134 tralala not this 00:03124 bar foo and we want this kryptonite but not this(!) 00:02134 foo bar and not this either 00:01234 dolor sit amet EOF
IOW, we want to extract sections that start, in regex terms, with "^0" and end with "(kryptonite|stalagmite)".
Been chomping on this for a bit, finding it a hard nut to crack. TIA!
