[XML] How to remove node?

[Winfried]

Hello,

Does someone know how to use pykml/lxml to remove a node?

I simply need to remove all occurences of "ExtentedData" nodes from a KML file, but this does nothing:

from lxml import etree
from pykml import parser

with open("input.kml") as f:
  doc = parser.parse(f)
root = doc.getroot()

folder = root.Document.Folder.Placemark
for pm in folder.getchildren():
	if pm.tag=="ExtendedData":
		folder.remove(pm)

outfile = open("output.kml","wb")
outfile.write(etree.tostring(doc, pretty_print=True))

Thank you.

Input file:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0">
<Document>
<name>KML Samples</name>
<Folder>
<name>Paths</name>
<Placemark>
<name>Tessellated</name>
<ExtendedData>
…
</ExtendedData>
</Placemark>
</Folder>
</Document>
</kml>

It's because pykml prepends "{http://earth.google.com/kml/2.0}" to each tag:

for pm in folder.getchildren():
	#How to forbid pykml to prepend {http://earth.google.com/kml/2.0} ?
	print(pm.tag)
	#if pm.tag=="ExtendedData":
	if pm.tag=="{http://earth.google.com/kml/2.0}ExtendedData":
		folder.remove(pm)

C:\>myscript.py input.kml
{http://earth.google.com/kml/2.0}name
{http://earth.google.com/kml/2.0}visibility
{http://earth.google.com/kml/2.0}description
{http://earth.google.com/kml/2.0}ExtendedData
{http://earth.google.com/kml/2.0}LineString

Is there a way to prevent it from doing so?
