<?xml version="1.0" encoding="iso-8859-1" ?>
<packages>
<package id="firefox" name="FireFox 3.5" >
<download url="http://download.mozilla.org/?
product=firefox-3.5&os=win&lang=fr" />

i know that & is a special caracter in xml

but how to parse the file

here is what i do :
filename = "file.xml"
xml = etree.parse(filename)
xml = ET.parse(filename)
for group in xml.getiterator('package'):
print group.get('id')

Sorry, my English fails to parse that. If that was a question, could you
rephrase it, please?

In case you want to know if the URL keeps working if you replace '&' by
'&amp;' in your XML file, then the answer is that it will actually /start/
working that way, because it will not work the way you show above. An XML
parser will return the URL as expected.

Note that it's also best to use an XML toolkit to actually generate XML, in
case you wrote the above file programmatically.

sorry for my english
thanks again for your answer


i did that ....

o = open("output.txt","w")
data = open(filename).read()
o.write( re.sub('&(?!amp;|quot;|nbsp;|gt;|lt;|laquo;|
raquo;|copy;|reg;|bul;|rsquo', '&amp;', data) )
o.close()
shutil.move
("output.txt",filename)
xml = etree.parse(filename)
xml = ET.parse(filename)

it's dirty but works

Absolutely no reason to write a file here. Use ET.fromstring().

And, just to repeat my question in other words: can't you just fix the
'XML' file before hand? I.e. is it a broken XML file coming from an outside
source that you cannot control, or did you create it yourself?
