user19027: Is there any way by which I can receive each and every Bitcoin transaction that takes place on the Bitcoin network(not only my own wallet's transactions)? Just the way Blockchain.info provides a transaction stream no matter who made them and to whom they are going? 
Can txindex=1 helps in this regard too?

user21052: Jeff Garzik's PyNode will, by default, connect to a Bitcoin Core running on local host a as a full node and download each transaction your node relays to it.  If you know Python, you can add extra triggers and post-processing to it.
Note, PyNode seems to be abandonware, and I think you currently need to hack it to get it to work with the latest versions of python-bitcoinlib.  It may still work with an older version of python-bitcoinlib.  You may also have better luck with PyNode2, a fork of the original PyNode.
