id is a tag so it is a OBJECT Element with attributes accessible by
dictionnary x.attrib[key] and x.text for tag content text.
canonical string representation of your Element object: Obj.id :> <Element
'result' at [mem addr]
And root is also an Element but the parent of id and name childs => composite
pattern.
For result use iterator as below (not tested but should be ok):
*_/#Parsing:/_
doc = ElementTree()
doc.parse(xmlFile)*
*_/#iteration over tag element:/_
ids = []
names =[]
for result in doc.iter('result'):
idElem = result.find('id')
*** nameElem = result.find('name')**
* ids.append(idElem.text)
names.append(nameElement.text)
final = zip(ids, names)
*
You are not obliged to provide the full XPATH. Etree search for you.

Hi all,
I am using, and very much enjoying, the ElementTree library. However,
I have hit a problem. Say I have something along the lines of:
<service>
<message>Message from Service</message>
<version>1.0</version>
<list>
<result>
<id>1</id>
<name>result 1</name>
</result>
<result>
<id>2</id>
<name>result 2</name>
</result>
</list>
</service>
In my ResultSet class, I parse this to get the text of elements like
message or version. Then, I use root.findall("list/result") and
iterate over the result, passing to a second function which parses the
passed-in elements into Result objects. For example:
all=root.findall("list/result")
for i in all:
self.mylist.append(Obj().parse(i))
In Obj.parse(), the element passed in is treated like this:
def parse(data):
root=data.getroot()
self.id=root.find("id").text
self.name=root.find("name).text
Printing the results of the above through Obj.id or Obj.name gives me
odd behavior:
print Obj.id :> <Element 'result' at [mem addr]
print self.id :> None
What is going on? Does the root change when I call find()? Why would
an Element object get used when I clearly say to use the text of the
found element? TIA.
