xml : remove a node with dom

[alain walter]

Hi,
You're right for my post code : I extract it from a more complicated
context.
However, the solution you propose produce the line <aixm:elevation
uom="M"/> not a blank line.
Finally, I've found a good solution by using :

from xml.dom.ext import PrettyPrint
from xml.dom.ext.reader.Sax2 import FromXmlStream

dom = FromXmlStream("my_file")
testRemoving(dom)
PrettyPrint(dom)

def testRemoving(self,dom) :
	for node1 in dom.childNodes:
		if node1.nodeType == node1.ELEMENT_NODE:
			for node in node1.childNodes:
				if node.nodeValue == "xxx_toremove_xxx":
					dom.removeChild(node1)
		testRemoving(node1)
