Hi, here is a better example, explaining what i want. INPUT

This is to test<X-REF REFID="FN001">1</X-REF> some more text. <FTN ID="FN001">Example111</FTN>

This is to test<X-REF REFID="FN002">2</X-REF> some more text. <FTN ID="FN002">Example222</FTN>

This is to test<X-REF REFID="FN003">3</X-REF> some more text. <FTN ID="FN003">Example333</FTN>

EXPECTED OUTPUT

This is to test<X-REF REFID="FN001">1<FTN>Example111</FTN></X-REF> some more text.

This is to test<X-REF REFID="FN002">2<FTN>Example222</FTN></X-REF> some more text.

This is to test<X-REF REFID="FN003">3<FTN>Example333</FTN></X-REF> some more text.

This is the full perl script now i am using

open(IN, "<temp.in") || die "\n Can't open file\n $!\n";

open(OUT,">temp.out");

## Search for FTN

my %values;

while(<IN>) {

if(s/\<FTN ID\=\"FN(\d{3})\"\>(.+?)\<\/FTN\>/\<FTN$1\>/) {

$values{$1} = $2;

}

}

## replace X-REF

while(<IN>) {

s/(<X-REF REFID="FN(\d{3})">)(.+?)(<\/XREF>)/$1$values{$2}$3/;

print OUT;

}

close(IN);

close(OUT);

But i don't get any output in temp.out

In my input file X-REF occurs first and FTN occurs next. So my script is not working properly
