I am modifying an XML file to change , into <,> (<,>). However when I find an empty element, it returns None.
My original XML value would be something like:
Thank you,
My original XML value would be something like:
Output:<element SourceRef="List_01" GroupName="Lists">
<body>
<p><span class="bold">ListElements</span>Element1 val1, Element2 val2; secondElement List</p>
</body>
<element>
Output:<element SourceRef="List_01" GroupName="Lists">
<body>
<p>None<span class="bold">ListElements</span>Element1 val1<,> Element2 val2<;> secondElement List</p>
</body>
<element>
Output:<element SourceRef="List_01" GroupName="Lists">
<body>
<p><span class="bold">ListElements</span>Element1 val1<,> Element2 val2<;> secondElement List</p>
</body>
<element>
if __name__=='__main__':
parser = ArgumentParser()
parser.add_argument('-f', '--file', help='Path to the file to process')
args = parser.parse_args()
xpath_expr = "//Default:Element[starts-with(SourceRef,'List_') \
or GroupName='Lists']/descendant::*"
if args.file:
#elements = get_element(args.file, xpath_expr, nsd)
filepath = Path(args.file)
elements = []
if filepath.exists() and filepath.is_file():
parser = et.parse(str(args.file))
root = parser.getroot()
elements = root.xpath(xpath_expr, namespaces=nsd)
for element in elements:
print(element)
if element.text != None or element.tail != None:
text = str(element.text)
if element.text == None:
print('Empty element: ', element.text)
text = text.replace(',', '<,>')
text = text.replace(';', '<;>')
tail = str(element.tail)
tail = tail.replace(',', '<,>')
tail = tail.replace(';', '<;>')
if text != None:
element.text = text
if tail != None:
element.tail = tail
#element = stringify_children(element)
#print('Element: ', element,', Text: ', element.text, '\n',
# 'Element: ', element, ', Tail: ', element.tail)
tree = et.ElementTree(root)
print(tree)
if element.text == None or element.tail == None:
element.clear()
tree = et.ElementTree(root)
tree.write(args.file, pretty_print=True)Any ideas why do I get a None for the empty tags <p>? And how can I prevent it.Thank you,
