here i want to replace server name from gIntegraHost to gTestRunHost but only between <TCPSampler and curl but after firing the below command only first instance is getting replaced not the other one.

sed '1,/<TCPSampler/!{ /curl.*END/,/<TCPSampler/!s/{gIntegraHost}/{gTestRunHost}/; }' file1 >aaa

Please suggest if i can do anything to solve it.

Please edit your post and and surround the content of the file with the CODE tags making it ending with [/CODE] and beginning with [CODE] to make it easier to read.

I want gIntegraHost to be replaced with gTestRunHost only where there in curl between<TCPSampler and </TCPSampler>. In below case it should not get replaced

<TCPSampler guiclass="TCPSamplerGui" testclass="TCPSampler" testname="Date" enabled="true">
<stringProp name="TestPlan.comments">This will clear any existing content in the webdav cache</stringProp>
<stringProp name="TCPSampler.server">${gIntegraHost}</stringProp>
<boolProp name="TCPSampler.reUseConnection">false</boolProp>
<stringProp name="TCPSampler.port">${gTcpShellPort}</stringProp>
<boolProp name="TCPSampler.nodelay">false</boolProp>
<stringProp name="TCPSampler.timeout"></stringProp>
<stringProp name="TCPSampler.request">date
END
</stringProp>
<stringProp name="ConfigTestElement.username"></stringProp>
<stringProp name="ConfigTestElement.password"></stringProp>
</TCPSampler>

And in This case it should be replaced

<TCPSampler guiclass="TCPSamplerGui" testclass="TCPSampler" testname="Curl Request 1" enabled="true">
<stringProp name="TCPSampler.server">${gIntegraHost}</stringProp>
<boolProp name="TCPSampler.reUseConnection">false</boolProp>
<stringProp name="TCPSampler.port">${gTcpShellPort}</stringProp>
<boolProp name="TCPSampler.nodelay">false</boolProp>
<stringProp name="TCPSampler.timeout"></stringProp>
<stringProp name="TCPSampler.request">cd /tmp
rm -f resp.data
curl -v -x ${gIntegraHost}:${gIntegraPort} http://${gTestOSHost}${gTestOSPath}video01.mp4 -H &quot;Pragma: no-cache&quot; --range 500000-1000000 -A &quot;${lUserAgent}&quot; -o resp.data
END
</stringProp>
<stringProp name="ConfigTestElement.username"></stringProp>
<stringProp name="ConfigTestElement.password"></stringProp>
</TCPSampler>

Hope i explained more clearly now.

The following perl script should work.
At a command prompt, type perl scriptname.pl < inputfile > outputfile

If you find a better or shorter way, please post it here for us to see!

<CODE>
use strict;
use warnings;

my $line;
my $inside_tag = 0;
my $has_curl = 0;

while ($line = <>) {
if ($line =~ /<TCPSampler/) {
$inside_tag = 1;
}
if (lc($line) =~ /<curl/) {
$has_curl = 1;
}
if ($line =~ /<\/TCPSampler/) {
$inside_tag = 0;
$has_curl = 0;
}
if ($inside_tag and $has_curl) {
$line =~ s/gIntegraHost/gTestRunHost/g;
}
print $line;
}
</CODE>

... or replacing the angle brackets <> surrounding CODE by square ones [] for better readability :

Sorry. It did not work. gIntegraHost did not get replaced at any place.

Hi.

Try this:
The logic is as follows: collect all lines between '<TCPSampler' and '</TCPSampler' in the pattern space; after that if there is 'curl' in pattern space, then perform substitution globally (note the `g' flag).

Sorry it did not work.
Is it working for you..?

Yes, it works for me. Please copy-paste corresponding text from terminal here, I'm just curious what's wrong. Also post input data using the [CODE]..[/CODE] tags to preserve formatting.
