How to match values in double quotes?

I'd like to mask out sensitive credit card details. Therefore trying to create matcher that finds:

  • that there is a CreditCard tag
  • that the same line has a Number field
  • that the same line has a CVC field

<CreditCard Number="123456789" CVC="111" />

Then I want to replace the numbers/values that are found. So far I have: (CreditCard.*CVC=").*?". This would match the string CreditCard Number="123456789" CVC="111".

What do I have to change so that only the numbers inside either CVC or Number double quotes are matched?

Try XPath instead of Regex. – Bergi
What language are you using? It would probably be a much better idea to use an XML parser – Explosion Pills
Java, but the string where the XML is placed does not ONLY consist of xml, but lot's of other data. So I cannot use a parser... – membersound
Are those attributes always in this order? Or could CVC occur before Number? – Tim Pietzcker
Don't parse XML with regexes – alroc

Lookahead and Lookbehind are the magic words. Here is an example to match your CVC number...

(?<=CVC=\")\d+(?=\")
