Help with data re-arrangement problem facing
Input file:
Code:
<symbol>Q9Y8G1</symbol>
<name>Q9Y8G1_EMENI</name>

<symbol>Q6V953</symbol>
<symbol>Q5B8K1</symbol>
<name>Q6V953_EMENI</name>

<symbol>G1A416</symbol>
<name>G1A416_9FUNG</name>

<symbol>D4N894</symbol>
<name>D4N894_PLEER</name>

<symbol>B0FFU4</symbol>
<symbol>B0LF02</symbol>
<symbol>B0LF04</symbol>
<symbol>B0LF05</symbol>
<symbol>B0LF07</symbol>
<symbol>B0LF08</symbol>
<name>B0FFU4_9HYPO</name>
.
.

Desired output file:
Code:
Q9Y8G1    Q9Y8G1_EMENI
Q6V953/Q5B8K1    Q6V953_EMENI
G1A416    G1A416_9FUNG
D4N894    D4N894_PLEER
B0FFU4/B0LF02/B0LF04/B0LF05/B0LF07/B0LF08    B0FFU4_9HYPO
.
.

Condition to generate desired output file:
1. Content in between "<symbol>" and "</symbol>" should represent data in column 1 of desired output file;
2. If more than one symbol share one "<name>", add "/" to represent the sharing relationship;
3. Content in between "<name>" and "</name>" should represent data in column 2 of desired output file;

"\n" can be treat as field separator of each group of data.

Thanks with any advice.

Try this...
Code:
awk -F"<symbol>|</symbol>|<name>|</name>" '/symbol/{x=x?x"/"$2:$2}/name/{print x"\t"$2;x=""}' input_file

here is your code dude...

Code:
cat share.txt
<symbol>Q9Y8G1</symbol>
<name>Q9Y8G1_EMENI</name>

<symbol>Q6V953</symbol>
<symbol>Q5B8K1</symbol>
<name>Q6V953_EMENI</name>

<symbol>G1A416</symbol>
<name>G1A416_9FUNG</name>

<symbol>D4N894</symbol>
<name>D4N894_PLEER</name>

<symbol>B0FFU4</symbol>
<symbol>B0LF02</symbol>
<symbol>B0LF04</symbol>
<symbol>B0LF05</symbol>
<symbol>B0LF07</symbol>
<symbol>B0LF08</symbol>
<name>B0FFU4_9HYPO</name>

Code:
#!/bin/sh
 

while read line
do
        if [[ `expr match "$line" ".*symbol.*"` != "0" ]]
        then
                echo -n "$line" | awk -F '>' '{printf $2}' |  awk -F '<' '{printf $1}'
                echo -n "/"
        fi

        if [[ `expr match "$line" ".*name.*"` != "0" ]]
        then
                echo -n "         "
                echo "$line" | awk -F '>' '{print $2}' |  awk -F '<' '{print $1}'
        fi
done < share.txt

Code:
perl -ne 'if(/<symbol>/../<\/name>/){chomp;if(/symbol/){print "/" if($cnt!=0);s/[<\/symbol>]//g;print;$cnt++}if(/name/){s/[<\/name>]//g;print "\t$_\n";$cnt=0}}' inputfile

Alternate awk solution..
Code:
awk -F'[><]' '/symbol/{x=x"/"$3;++n;next}n{print substr(x,2),$3;x=n=""}' inputfile

Thanks ahamed.
Do you mind to explain a little bit more about your code?
I'm quite confusing about following code:
Code:
'/symbol/{x=x?x"/"$2:$2}/name/{print x"\t"$2;x=""}'

Apart from that, if my input file is look like:
Code:
<name>Q9Y8G1_EMENI</name>
<symbol>Q9Y8G1</symbol>

<name>Q6V953_EMENI</name>
<symbol>Q6V953</symbol>
<symbol>Q5B8K1</symbol>

<name>G1A416_9FUNG</name>
<symbol>G1A416</symbol>

<name>D4N894_PLEER</name>
<symbol>D4N894</symbol>

<name>B0FFU4_9HYPO</name>
<symbol>B0FFU4</symbol>
<symbol>B0LF02</symbol>
<symbol>B0LF04</symbol>
<symbol>B0LF05</symbol>
<symbol>B0LF07</symbol>
<symbol>B0LF08</symbol>

How should I edit your code to generate the following output?
Code:
Q9Y8G1_EMENI   Q9Y8G1
Q6V953_EMENI   Q6V953/Q5B8K1
G1A416_9FUNG   G1A416
D4N894_PLEER   D4N894
B0FFU4_9HYPO   B0FFU4/B0LF02/B0LF04/B0LF05/B0LF07/B0LF08

Thanks for advice.
