The following code:

import xml.etree.ElementTree as ET

essai = '''<?xml version='1.0' standalone='yes' ?>
<LVData xmlns="http://www.ni.com/LVData">
<Version>18.0.1f4</Version>
<Cluster>
<Name>Out</Name>
<NumElts>34</NumElts>
<DBL>
<Name>Amplitude_Signal</Name>
<Val>0.30000000000000</Val>
</DBL>
</Cluster>
</LVData>'''          

root = ET.fromstring(essai)
for child in root[1]:
    print(child.tag, child.attrib)

produces empty attribute results:

{http://www.ni.com/LVData}Name {}
{http://www.ni.com/LVData}NumElts {}
{http://www.ni.com/LVData}DBL {}

Why?

An XML attribute is <a key="value">element text</a> key in this case. The elements in the sample have no attributes. — LMC

<Name>Amplitude_Signal</Name> That element has no attributes. What were you expecting? "Amplitude_Signal" is the text, not an attribute. — John Gordon

Well, wait a bit, "<DBL> <Name>Amplitude_Signal</Name> <Val>0.30000000000000</Val> </DBL>" contain two fields, how to acces it? — Baps131

In <Name>Amplitude_Signal</Name>, I was thinking that Amplitude_Signal was the attribute.

This is only the "text".

So

child.attribute

should be replaced by:

child.text

returning

{http://www.ni.com/LVData}Name Out
{http://www.ni.com/LVData}NumElts 34
{http://www.ni.com/LVData}DBL
