sed replace range of lines with a single word - regex

Question

I tried my best to get this and had little luck, I have following file and I want to replace
first “<Connector port="8080"” xml block with ‘xxxx’
Before :
<!-- A "Connector" represents an endpoint by which requests are received
and responses are returned. Documentation at :
Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
Java AJP Connector: /docs/config/ajp.html
APR (HTTP/AJP) Connector: /docs/apr.html
Define a non-SSL HTTP/1.1 Connector on port 8080
-->
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<!-- A "Connector" using the shared thread pool-->
<!--
<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
-->
After :
<!-- A "Connector" represents an endpoint by which requests are received
and responses are returned. Documentation at :
Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
Java AJP Connector: /docs/config/ajp.html

-->
xxxx
<!-- A "Connector" using the shared thread pool-->
<!--
<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
-->
I got the matching string to print using following sed command :
sed -n '/<Connector port="8080"/,/>/p' filename
However I’m unable to develop this to get above output.

Answer 1

This sed should do the trick on your sample input (but gets overzealous if you have more than one <Connector port="8080" section):
sed '/<Connector port="8080"/,/>/{ s/<Connector.*/xxxx/; t; d }'
But handling this robustly calls for an XML parser. Example:
#!/usr/bin/env ruby
require 'rexml/document'
include REXML
d = Document.new(File.read(ARGV[0]))
e = d.get_elements('//Connector[#port="8080"]').first
if !e.nil?
e.parent.insert_after(e, Text.new('xxxx'))
e.parent.delete(e)
end
File.open(ARGV[0],'w'){|f| f.print(d) }

Answer 2

sed '/<Connector port="8080"/,/>/ {
N
/>/ s/.*/xxxx/
}' YourFile
load the section of connector before changing it to xxxx, this allow you to eventually test something on it (but not better than pobrelkey if not)

Answer 3

Thanks all for the answers , they worked well .Appriciate it:
Also i got following from one of my firend which also a answer to this using awk
awk '/<Connector port/ {
print "abc"
getline
do {
getline
} while (index($0, ">") == 0)
getline
}
// { print $0}' < 1.txt
