I'm trying to get the values from this web page:

```
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<ArrayOfVwHistoryDetail xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://tempuri.org/">
<vwHistoryDetail>
<idVariable>2561</idVariable>
<DateTime>2020-12-01T00:00:00</DateTime>
<idPeriodType>1</idPeriodType>
<Value>28671555</Value>
<ValueDetail>4415</ValueDetail>
</vwHistoryDetail>
<vwHistoryDetail>
<idVariable>2561</idVariable>
<DateTime>2020-12-02T00:00:00</DateTime>
<idPeriodType>1</idPeriodType>
<Value>28675970</Value>
<ValueDetail>4279</ValueDetail>
</vwHistoryDetail>
<vwHistoryDetail>
<idVariable>2561</idVariable>
<DateTime>2020-12-03T00:00:00</DateTime>
<idPeriodType>1</idPeriodType>
<Value>28680249</Value>
<ValueDetail>3975</ValueDetail>
</vwHistoryDetail>
<vwHistoryDetail>
<idVariable>2561</idVariable>
<DateTime>2020-12-04T00:00:00</DateTime>
<idPeriodType>1</idPeriodType>
<Value>28684224</Value>
<ValueDetail>4236</ValueDetail>
</vwHistoryDetail>
</ArrayOfVwHistoryDetail>

```

I tested with this code:

```
import xml.etree.ElementTree as ET
from urllib import request

url = "http://SomeSite/WebService.asmx/LoadVariableHistory?username=USERNAME&password=PASSWORD&variableName=CBT2_G_PRM_FB2&startDateTime=2020-12-01&endDateTime=2020-12-02&sampling=3"

print ("Obter: ", url)
html = request.urlopen(url)
data = html.read()
print("Obtido: ",len(data),"caracteres")

tree = ET.fromstring(data)
results = tree.findall('Value')
for i in results:
  print(i)

```

I hid the full URL for safety reasons.
What I'm doing wrong to not get the values? I need to get thru this part so I can build a dictionary with DataTime : Value

Thank you in advance
