name space issue can be resolved registering name space i have no issue with that, only concern is xml parser has no effect when http things are added...

No, the parser works fine. Your attempt to register a default namespace
didn't work. Those "http things" *are* the namespace issue!

The following version of your code works. *Try it.* It finds the servlet
element in the document object, removes it, and writes out XML text
without the servlet element. (It seems to invent another namespace
prefix. That doesn't change the meaning of the document.)

import xml.etree.ElementTree as ET

ns = { 'x' : "http://xmlns.jcp.org/xml/ns/javaee" }

tree = ET.parse('sample.xml')
root = tree.getroot()

for servlet in root.findall('x:servlet', ns):
    servletname = servlet.find('x:servlet-name', ns).text
    if servletname == "controller":
        root.remove(servlet)

tree.write('output.xml')

yup its working well if i include register namespace, else i am getting ns:0  in every line of output.xml.

But its removing top line
<?xml version="1.0" encoding="ISO-8859-1"?>

That's a namespace prefix for each element name that is in the default
namespace. If the ET.register_namespace has the effect of making that
the default namespace in the output, fine, you can use it.

The important thing is that you can read your output.xml back in, using
the XML parser, and it has the intended meaning.

Not a problem. You can still read your output.xml back in, using the XML
parser, and it will have the same meaning as it would have had with this
declaration.

The write() method allows you to specify an encoding and/or require an xml 
declaration:

Hi Peter,

Thanks for reminding about basic write method syntax...its working :)


<?xml version='1.0' encoding='iso-8859-1'?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="3.1" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee                        http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
    <servlet-mapping>
      <servlet-name>graph</servlet-name>
      <url-pattern>/graph</url-pattern>
    </servlet-mapping>


    <session-config>
      <session-timeout>30</session-timeout>
    </session-config>


Here is the change:

tree.write('output.xml',encoding="ISO-8859-1",xml_declaration=True)

Thank you all especially jussi and pete..

It's a namespace issue, and your method of registering a default
namespace isn't working. It's a frustrating failure mode: no error
message, no nothing :)

Try defining a namespace prefix in your method calls, and using that
prefix in element names:

ns = { 'x' : "http://xmlns.jcp.org/xml/ns/javaee" }

for servlet in root.findall('x:servlet', ns):
    servletname = servlet.find('x:servlet-name', ns).text

I got this from here:
https://docs.python.org/3/library/xml.etree.elementtree.html#parsing-xml-with-namespaces

Note that the namespace prefix - I chose to use 'x' - has no meaning.
It's the association of the prefix that you use to the URI that is the
name of the namespace that does the job.

I put some code I did before for the xmlns:

                              xml_root = ET.ElementTree(ET.fromstring(xml_decoded)).getroot()
                              for elem in xml_root.getiterator():
                                             if('{http://request.messagepush.interfaces.comviva.com/xsd}shortCode'==elem.tag):
                                                            shortCode = (elem.text).rstrip()
                                             if('{http://request.messagepush.interfaces.comviva.com/xsd}text'==elem.tag):
                                                            send_text = (elem.text).rstrip()
                                             if('{http://request.messagepush.interfaces.comviva.com/xsd}item'==elem.tag):
                                                            subscribers = (elem.text).rstrip()
                              result_sms = send_sms(subscribers,shortCode,send_text)

Reuse it.

I don't know what this does, but probably not what you expected.

I think you have to specify the namespace:

for servlet in root.findall('{http://xmlns.jcp.org/xml/ns/javaee}servlet'):
    servletname = servlet.find(
        '{http://xmlns.jcp.org/xml/ns/javaee}servlet-name').text

>         if servletname == "controller":

You could have added a print statement to verify that the line below is executed.
