Sed command to find and replace string with ip address+characters

veryangryman

Hi folks - hope you can help. I have this to replace any IP address with the word ThisIsATest in the file SiteBasic.xml


sed 's/[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}/ThisIsATest/g' SiteBasic.xml

Works a charm

Problem is, i want it only to replace lines with this string

ossCorbaNameServer="1.2.3.4"/>

or in other words

ossCorbaNameServer="<ip address>"/>

All help much appreciated.

Put that text into the regex and then put brackets around the pieces you want to keep and reference them in the 2nd half of the regex

For example:
's/\(keep=\)[0-9]\(other\)/\1ThisIsaTest\2/'
Should return:
keep=ThisIsaTestother

My escaping of chars is probably off but hopefully you get the idea.

This might work:

sed 's/\(ossCorbaNameServer="\)[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}\("\/>\)/\1ThisIsATest\2/g' SiteBasic.xml
