[xml-dev] IP address pattern matching

[Matt Loryman <matt.loryman@viewgate.com>]

Hi all,

Just for your interest this is what i decided to go with for providing a
pattern match for IP addresses.
Essentially this means "four groups of one to three numbers between zero and
nine separated by periods".
Doesn't cover all eventualities i know, but then again it doesn't stop
somebody providing a perfectly valid
but inaccurate IP address!


         <simpleType>
            <restriction base="string">
              <pattern
value="[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}"/>
            </restriction>
          </simpleType>
