How to retrieve all validation differences when comparing XML file with XSD file
I have been trying to find the validation of XSD file with XML file. But unfortunately I am getting only the first difference while checking the files. I am using asssertValid() which only giving the first difference i.e., "Pane" from the file. It should find all the difference i.e., "Pane" and "Subpanel". I want all the validation difference in the log file. Could you please help me find all the differences.
Python Code
from lxml import etree
import traceback
def validate_xml_and_xsd_files(xml_path: str, xsd_path: str):
result = False
try:
xmlschema_doc = etree.parse(xsd_path)
xmlschema = etree.XMLSchema(xmlschema_doc)
xml_doc = etree.parse(xml_path)
result = xmlschema.validate(xml_doc)
xmlschema.assertValid(xml_doc)
except Exception as ex:
print("Exception raised-->", ''.join(traceback.format_exception(etype=type(ex), value=ex, tb=ex.__traceback__)))
finally:
return result
if __name__ == "__main__":
file_path = "C:\\Users\\"
source_file_path = file_path + 'outputmetadata.xml'
schema_file_path = file_path + 'XMLValidator.xsd'
if validate_xml_and_xsd_files(source_file_path, schema_file_path):
print('Validation Successful w.r.t XML and XSD files.')
else:
print('Validation Unsuccessful w.r.t XML and XSD files')
