use awk instead, but the rest of the syntax should be similar.

Code:
# cat tst
<TRANSFIELD DATATYPE ="double" DEFAULTVALUE ="" DESCRIPTION ="" FIELD ="EMP_KEY" PICTURETEXT ="" PORTTYPE ="OUT" PRECISION ="15" SCALE ="0"/>
<TRANSFIELD DATATYPE ="double" DEFAULTVALUE ="" DESCRIPTION ="" FIELD ="I_EMP_KEY" PICTURETEXT ="" PORTTYPE ="OUT" PRECISION ="22" SCALE ="5"/>
<TRANSFIELD DATATYPE ="string" DEFAULTVALUE ="" DESCRIPTION ="" FIELD ="DEPT_KEY" PICTURETEXT ="" PORTTYPE ="OUT" PRECISION ="7" SCALE ="0"/>
<TRANSFIELD DATATYPE ="string" DEFAULTVALUE ="" DESCRIPTION ="" FIELD ="MGR_NAME" PICTURETEXT ="" PORTTYPE ="OUT" PRECISION ="32" SCALE ="0"/>
<TRANSFIELD DATATYPE ="decimal" DEFAULTVALUE ="" DESCRIPTION ="" FIELD ="SAL_CODE" PICTURETEXT ="" PORTTYPE ="OUT" PRECISION ="3" SCALE ="0"/>
<TRANSFIELD DATATYPE ="string" DEFAULTVALUE ="" DESCRIPTION ="" FIELD ="PCT_RISE" PICTURETEXT ="" PORTTYPE ="IN" PRECISION ="7" SCALE ="0"/>

# awk -F'"' -v V="I_EMP_KEY" '{for(i=1;i<=NF;i++) if ($i==V) print $(i+6)":"$(i+8)}' tst
22:5

or
Code:
# awk -F'"' -v V="EMP_KEY" '{for(i=1;i<(NF-8);i++) if ($i==V) print $(i+6)":"$(i+8)}' tst
15:0

Stick a double quote just before the variable; that way you are matching against "EMP_KEY and I_EMP_KEY won't be a problem. You can put another double quote behind it for the same reason (won't match EMP_KEY_2).
Code:
 awk  '/"'$frm_inst'"/ {for(i=1;i<=NF;i++){if($i~"PRECISION|SCALE") { print gensub(/[^0-9]/,"","g",$(i+1)); } } }'
