Substring Problem with sed . . .

Greetings.

I'm looking to isolate the first occurrence of an arbitrary substring which may be present at any particular line in a given file. The enclosing end markers for the target in our thought problem are string" and ". The complete string and surrounding text could look something like this,
Code:
a bunch of lines
"blah' blah string"1.2.3.4.5.6" "sputter" "thump!"
another line
etc

...with 1.2.3.4.5.6 being our target substring.

To scrape this problem off my plate, I've tried numerous approaches; including things like
Code:
sed -i '/string\"/,/\"/!d' ./testfile

...with much hair loss and screen damage Smilie

Any tips for "happy sedding" through this wicket?


Thanks!

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
