Removing children - Python - XML

[MadnessRed]

Hi, I am having some problems removing children from an xml node.

I had:

node = xmldoc.getElementsByTagName('types')[0]
for child in node.childNodes:
    print child.toxml()
    node.removeChild(child)

That just printed a few blank lines and did nothing. Then I tried:

node = xmldoc.getElementsByTagName('types')[0]
for child in node.childNodes:
    for grandchild in child.childNodes:
        print grandchild.toxml()
        child.removeChild(grandchild)

That emptied the children but still left them there.
eg

<types>
    <type>jpg</type>
    <type>png</type>
    <type>gif</type>
</type>

to

<types>
    <type/>
    <type/>
    <type/>
</type>

I would like to completely empty types.
Any suggestions?


edit: solved

node = xmldoc.getElementsByTagName('types')[0]
while len(node.childNodes) > 0:
    child = node.childNodes[0]
    print child.toxml()
    node.removeChild(child)
