Select all the elements by title tag and remove them using removeChild

Update:

from xml.dom import minidom
xmldoc = minidom.parse("book_xml.xml")

nodes = xmldoc.getElementsByTagName("title")

for node in nodes:
    parent = node.parentNode
    parent.removeChild(node) 

print xmldoc.toxml()

You can also write new changes to xml file by :

with open("result.xml","w") as fs:
    fs.write(xmldoc.toxml())
    fs.close()
