AttributeError when attempting to view dom.minidom.Element object in Variable Explorer

[greenorca]

Description

variable explorers list view crashes on opening nested xml elements

What steps will reproduce the problem?

1. extract content.xml from *.odt, load it into xml.dom.minidom object
2. variable2View = dom.getElementsByTagName(...) becomes a dom.minicompat.NodeList
3. open variable2View, and try to open one of the contained cells

What is the expected output? What do you see instead?
expected to see content of the xml node, got a crash instead

Please provide any additional information below

Thanks for reporting, but unfortunately your description is not complete. Please post the Python code you used to get variable2View along with a simple odt file we can use in our end to reproduce this problem.

Thanks!

Thanks for getting back to me, and my apologies for the incomplete information.
Instead of the odt file, I attached the content.xml extracted from the odt and had to rename it the txt...

content226_uifz_block6.txt

file = "content226_uifz_block6.txt"
if __name__ == '__main__':
    with open(file) as f:
        read_data = f.read()
        
    content = xml.dom.minidom.parseString(read_data)
    tables = content.getElementsByTagName("table:table")
    # the crash happens when opening the tables variable with VariableExplorer right after the above line

Generally speaking, the script does what I want it to do, extracting strings from the cells within tables[0] if I don't stop it. And sorry for dumping tables into writer documents, I know it is odd ;-)

I've reproduced and fixed this by just catching the error where it occurs, and you are now able to view the dom.minidom.Element just fine. PR incoming shortly. More complete code to reproduce:

from xml.dom.minidom import parseString

file = "Data/content226_uifz_block6.txt"
with open(file) as f:
    read_data = f.read()

    content = parseString(read_data)
    tables = content.getElementsByTagName("table:table")
