Accessor and tag in XML file using ElementTree
Thanks a lot for your reading. I apologize for asking this as a beginner as I am sure it is a simple answer. Any guidance is greatly appreciated.
I have an xml file that I am parsing with ElementTree
which has elements that look like this:
data.xml:
<?xml version="1.0" encoding="utf-8"?><listings><listing id="26496000" dateFirstListed="2012-10-13" dateLastListed="2013-10-06" market="SALE" propertyType="DETACHED" bedrooms="4" latestAskingPrice="314950"><address key="u935d·0" udprn="50812465" line1="12 Millcroft" line2="Millhouse Green" town="SHEFFIELD" postcode="S36 9AR" /><description> SOME TEXT HERE </description></listing>
I want to access the tag <description>
and <address key>
.
Using the guide outlined at https://docs.python.org/2/library/xml.etree.elementtree.html I write:
import xml.etree.ElementTree data = xml.etree.ElementTree.parse('data.xml') root = data.getroot()
and iterate over the children:
for child in root:
print child.tag, child.attrib
>
listing {'dateLastListed': '2013-10-06', 'dateFirstListed': '2012-10-13', 'propertyType': 'DETACHED', 'latestAskingPrice': '314950', 'bedrooms': '4', 'id': '26496000', 'market': 'SALE'}
This only gives me children for the tag <listing>
. How do I change the above expression to access <address key>
and <description>
?
Edit: The following guidelines on this matter Parsing XML with Python Accessors
I've tried writing:
for i in root.findall("listing"):
description = i.find('description')
print description.text
>
AttributeError: 'NoneType' object has no attribute 'text'

You can iterate over the lists one at a time and then get the inner children description
and address
. To access the attributes use the .attrib
attribute :
import xml.etree.ElementTree as ET
data = ET.parse('data.xml')
root = data.getroot()
for listing in root.findall("listing"):
address = listing.find('address')
description = listing.findtext('description')
print(description, address.attrib.get("key"))
