Hi all!
The simple problem is this: I have a file named example.html on my
harddisk and I want to extract from that file a block of text that
goes from the regex "foobar[0-9]" to the first occurrence of the regex
"abcdef[0-9]".
What's the Perl/command-line/single-line solution for this?
Thanks in advance for any help

It's my birthday, and I'm feeling generous. Here, have a fish:
perl -ln0777 -e'print $1 if /foobar[0-9](.*?)abcdef[0-9]/'
example.html
Then read:
perldoc perlrun
perldoc perlre
to understand what's happening.

Those are good for you.
A federally funded study has shown that people with the most birthdays...

Look for "Range Operators" (scalar context) in `perldoc perlop`.
perl -n -e 'print if /foobar\d/ .. /abcdef\d/' example.html

That will include all text before /foobar\d/ on the first line, and
all text after /abcdef\d/ on the last line. The OP said he wanted the
text that is between the two patterns.

But did they find a causal relationship, or was it more of a
statistical correlation?

It's causal. Those pesky February 29 birthdays keep throwing the
statistics off :)
