Dear Monks I have a xml file like this:

</S></TEXT><TEXT><S Entail="142" s_id="0">
Annan urges return to democracy in <REF C-ENTID="Nepal" EXT="Nepal" ID
+="104" S&#1058;YPE="PROPNAME">Nepal</REF></S><S Entail="138-139-142" 
+s_id="1">

+pal" EXT="Nepal" ID="105" S&#1058;YPE="PROPNAME">Nepal</REF> and urge
+d a return to democracy, after <REF C-ENTID="King Gyanendra Bir Bikra
+m" COMMENT="Coref direction is forward" EXT="King Gyanendra Bir Bikra

+he country</REF> 's coalition government and imposed an indefinite st
+ate of emergency.

I tried using regular expression and sed to get rid of all <REF .......> elements so my desired output would look like this:

</S></TEXT><TEXT><S Entail="142" s_id="0">
Annan urges return to democracy in Nepal</REF></S><S Entail="138-139-1
+42" s_id="1">

+ events in Nepal</REF> and urged a return to democracy, after King Gy
+anendra Bir Bikram</REF>
dismissed the country</REF> 's coalition government and imposed an ind
+efinite state of emergency.
</S><S Entail="138-139-143" s_id="2">

I had a sed line like this which does not work well :(

sed -r 's/<REF ([A-Za-z]*[-]{0,1}[A-Za-z]*=["].[A-Za-z0-9-]*.{0,1}[A-Z
+a-z0-9-]*.{0,1}[A-Za-z0-9-]*.{0,1}[A-Za-z0-9-]*.{0,1}[A-Za-z0-9-]*.{0
+,1}[A-Za-z0-9-]*.{0,1}[A-Za-z0-9-]*.{0,1}[A-Za-z0-9-]*)*>//g' input.x
+ml

Any idea how can I do it with perl? I do really appreciate :) Thanks
