I have tried to parse the above file in the following way:
import xmltodict
# wget -c https://raw.githubusercontent.com/galaxyproject/usegalaxy-playbook/c55aa042825fe02ef4a02d958eb811adba8ea45f/files/galaxy/usegalaxy.org/var/shed_tool_conf.xml
if __name__ == '__main__':
with open('tests/shed_tool_conf.xml') as fd:
doc = xmltodict.parse(fd.read())
tools_section = doc['toolbox']['section']['@name']
print tools_section
However, I have got the following error:
Traceback (most recent call last):
File "importTools2Galaxy.py", line 15, in <module>
tools_section = doc['toolbox']['section']['@name']
TypeError: list indices must be integers, not str
What did I do wrong?
This is because doc['toolbox']['section']
returns a list
of sections so you need to iterate over each section to get @name
value. You may want check if @name
is in given section. For that you may want to use .get
instead of ['@name']
with open('tests/shed_tool_conf.xml') as fd:
doc = xmltodict.parse(fd.read())
for section in doc['toolbox']['section']:
tools_section = section.get('@name')
print tools_section
