removing elements using python and lxml

I need to remove the following from this xml - 

<entry>
    <id>1234</id>
    <title>hello</title>
    <source>com.server.webclient.xxx</source>
    <xxx:component>
        <xxx:id>2134</xxx:id>
        <xxx:name>name</xxx.name>
    </xxx:component>
</entry>

What I want to do is remove <entry>, <id>, <title> and <source>

My code is trying to just delete ID right now but isn't returning an error but it isn't removing the values.

with open('c:\\temp\\%s.xml' % args.componentName, 'w') as f:
    xmlObject = etree.fromstring(r.content)
    for elem in xmlObject.xpath( '//id' ) :
        elem.remove(elem)
    f.write(etree.tostring(xmlObject, pretty_print=True))

This is what I want my XML to look like - 

<xxx:component>
    <xxx:id>2134</xxx:id>
    <xxx:name>name</xxx.name>
</xxx:component>

An easier option for you to achieve what you want would be to find the <xxx:component> element inside the <entry> component and write that to the file.

Example -

with open('c:\\temp\\%s.xml' % args.componentName, 'w') as f:
    xmlObject = etree.fromstring(r.content)
    reqElem = xmlObject.xpath('//xxx:component',namespaces=ns)   #ns should have the `xxx` prefix and whatever its actual namespace is
    if len(reqElem) == 1:
        f.write(etree.tostring(reqElem[0], pretty_print=True))
