Get all xml attribute values in python3 using ElementTree
Use findall()
to get all of the country
tags and get the name
attribute from the .attrib
dictionary:
import xml.etree.ElementTree as ET
data = """your xml here"""
tree = ET.fromstring(data)
print([el.attrib.get('name') for el in tree.findall('.//country')])
Prints ['Liechtenstein', 'Singapore', 'Panama']
.
Note that you cannot get the attribute values using an xpath expression //country/@name
since xml.etree.ElementTree
provides only limited Xpath support.
FYI, lxml
provides a more complete xpath support and therefore makes it easier to get the attribute values:
from lxml import etree as ET
data = """your xml here"""
tree = ET.fromstring(data)
print(tree.xpath('//country/@name'))
Prints ['Liechtenstein', 'Singapore', 'Panama']
.

I have the following xml file
<?xml version="1.0"?> <data> <country name="Liechtenstein"> <rank updated="yes">2</rank> <year>2008</year> <gdppc>141100</gdppc> <neighbor name="Austria" direction="E"/> <neighbor name="Switzerland" direction="W"/> </country> <country name="Singapore"> <rank updated="yes">5</rank> <year>2011</year> <gdppc>59900</gdppc> <neighbor name="Malaysia" direction="N"/> </country> <country name="Panama"> <rank updated="yes">69</rank> <year>2011</year> <gdppc>13600</gdppc> <neighbor name="Costa Rica" direction="W"/> <neighbor name="Colombia" direction="E"/> </country> </data>
I want to write python 3 code using ElementTree to get all country names. So the end result should be a
dict
orarray
of['Liechtenstein','Singapore','Panama']
I am trying to do this using Xpath but getting nowhere. So my code is as follows
import xml.etree.ElementTree as ET tree = ET.parse(xmlfile) root = tree.getroot() names = root.findall("./country/@name")
However the above does not work as I feel my xpath is wrong.

Vinay Joseph almost 10 yearsThank you. Is it possible to all names into an array in a single line.

Vinay Joseph almost 10 yearsFigured it out. Thanks.

alecxe almost 10 years@VinayJoseph I've also added an
lxml
option - just in case you are okay with using third-party modules. And also added links to the documentation.
