Try this:

irb(main):001:0> doc =<<EOF
irb(main):002:0" <script type="text/javascript">
irb(main):003:0"  google_ad_client = "pub-9423056098431875";
irb(main):004:0"  /* 300x250, created 6/10/09 */
irb(main):005:0"  google_ad_slot = "1755518182";
irb(main):006:0"  google_ad_width = 300;
irb(main):007:0"  google_ad_height = 250;
irb(main):008:0"  </script>
irb(main):009:0" EOF
=> "<script type=\"text/javascript\">\n google_ad_client =
\"pub-9423056098431875\";\n /* 300x250, created 6/10/09 */\n
google_ad_slot = \"1755518182\";\n google_ad_width = 300;\n
google_ad_height = 250;\n </script>\n"
irb(main):011:0> m = doc.match /google_ad_client = "(.*?)"/
=> #<MatchData "google_ad_client = \"pub-9423056098431875\""
1:"pub-9423056098431875">
irb(main):012:0> m.captures
=> ["pub-9423056098431875"]
