I have two solr indexes , Index A contains 100000 docs and B contains 110000
docs, A is subset of B, i have to perform operation where
A XOR B = result
and delete result.

If there are only 100'000 documents dump all document ids and make diff
If you're using linux based system you can just use simple tools to do it.
Something like that can be helpful

curl "http://your.hostA:port/solr/index/select?*:*&fl=id&wt=csv" > /tmp/idsA
curl "http://your.hostB:port/solr/index/select?*:*&fl=id&wt=csv" > /tmp/idsB
diff /tmp/idsA /tmp/idsB | grep "<\|>" | awk '{print $2;}' | sed
's/\(.*\)/<id>\1<\/id>/g' > /tmp/ids_to_delete.xml

Now you have file. Now you can just add to that file "<delete>" and
"</detele>" and upload that file into solr using curl
curl -X POST -d @/tmp/ids_to_delete.xml "http://your.hostA:port
/solr/index/upadte"
