解析python中有嵌套标签的xml文件

Question

i just want to parse one xml file which is like as

 <?xml version="1.0" encoding="UTF-8"?><Significant Major="3" Minor="0" Revision="1" xmlns="urn:reuterscompanycontent:significantdevelopments03"><RepNo>0091N</RepNo><CompanyName Type="Primary">XYZ</CompanyName><Production Date="2017-02-23T18:10:39" /><Developments><Development ID="3534388"><Dates><Source>2017-02-23T18:18:32</Source><Initiation>2017-02-23T18:18:32</Initiation><LastUpdate>2017-02-23T18:23:26</LastUpdate></Dates><Flags><FrontPage>0</FrontPage><Significance>1</Significance></Flags><Topics><Topic1 Code="254">Regulatory / Company Investigation</Topic1></Topics><Headline>FTC approves final order settling charges for Abbott's deal with St. Jude Medical</Headline></Development></Developments></Significant>

I just want to parse the Development tag and parse its every nested tag i have below code:

import xml.etree.cElementTree as ET
tree = ET.ElementTree(file='../rawdata/SigDev_0091N.xml')

#get the root element
root = tree.getroot()

#print root.tag, root.attrib

for child in root:
#print child.tag, child.attrib
    name = child.tag
    print name
    print 'at line 13'
    if name is 'Developments':
        print 'at line 15'
        for devChild in name['Developments']:
            print devChild.tag,devChild.attrib

it is not going inside the if block, i dont know why?

Answer 1

Checking name is 'Developments' always return false as child.tag is returning the value in {xmlns}tagname format.

For your case:

name = {urn:reuterscompanycontent:significantdevelopments03}Developments

You may refer to the answer of this question .

Simple string methods strip() , find() , split() or re can help you to skip the namespace for comparison.
