Hi

I have the following code, where i parse an html text and use a regex to get all the src attribute values.
The regex works fine on a subset of sites.
My problem is reading the values the regex found...it always gives me an error.
The error is the following
Exception in thread "main" java.lang.IllegalStateException: No match found
at java.util.regex.Matcher.group(Matcher.java:468)
at java.util.regex.Matcher.group(Matcher.java:428)
at httpclientregex.Main.main(Main.java:52)
Java Result: 1


And the code is as following


Am i missing something??

Any suggestions would be greatly appreciated
