Regexp help in getting the IP address

Hi All,

We have to get the IP address from the following xml event :

Threshold123(10.77.11.92)2003-06-05T06:20:00.171Z<name>cdfjdp01</name><i
pa
ddress>10.77.11.48</ipaddress><entity>Cisco
CNS-PerfE</entity><version>dev</version><time>2003-06-05T06:20:00.172Z</
time>criticalcleared.1.3.6.1.2.1.2.2.1.10.31885616724LTE2000000000com.ci
sco.das.MibCollector.MibCollector

In general, we should be able to get any CLASS A/B/C Ip address (
1.1.1.1/22.1.1.1/172.29.102.9)

But the issue is, the start of the string contains "threshold<digits>"
followed by<ipaddress> ?

How I differentiate between the ip address and the digits ? Any regexp
which can achieve the same ?

Please let us know on this.

Thanks much in Advance,
Saika
