Using http://www.xpathtester.com/ to fixup the xml I get

<?xml version="1.0" encoding="UTF-8"?>
<book xmlns:book="http://generated.ns/book">  
  <book:chapter id="bk444444ch1" type="CHAPTER"> 
    <book:locator xmlns:xlink="http://www.w3.org/1999/xlink" xlink:hre

And then setns/query using xmllint --shell

$ xmllint.exe --shell ravi06-03.xml
