yes
yes
You might try something like this (where input string is 's')
Pattern p = Pattern.compile("/([a-f0-9\\-]+)\"");
Matcher m = p.matcher(s);
while (m.find()) {
System.out.println(m.group(1));
}

Sorry - let me be a little more precise:
Capture groups of lower case hex characters followed by hyphens four times (the remainder of pattern is explained by the first seven words [only] of this sentence)
