Input file

<data id>="1">\
</data>\
<data id>="2">\
</data>\
<code>="1" target="2">\
</code>\
<data id>="1">\
</data>\
<data id>="2">\
</data>\
<code>="1" target="2">\
</code>\
<data id>="1">\
</data>\
<data id>="2">\
</data>\
<code>="1" target="2">\
</code>\
.
.

Desired output result:

<data id>="1">\
</data>\
<data id>="2">\
</data>\
<code>="1" target="2">\
</code>\
<data id>="3">\
</data>\
<data id>="4">\
</data>\
<code>="3" target="4">\
</code>\
<data id>="5">\
</data>\
<data id>="6">\
</data>\
<code>="5" target="6">\
</code>\

My input file is only "1" and "2".
However, those "data id" and "code" in my desired output result should be descending order until end up the file.

Thanks for any advice.

Try next command:

$ perl -pe 's/(?<=<data id>=")\d+(?=">)/++$data_id/e ; s/\d+/++$code_target/ge if /^<code>=/ && /target=/' infile

</data>\
<data id>="2">\
</data>\
<code>="1" target="2">\
</code>\
<data id>="3">\
</data>\
<data id>="4">\
</data>\
<code>="3" target="4">\
</code>\
<data id>="5">\
