I already have an XML file that acts as the configuration backbone for my project, but I suspect it carries validation issues that are starting to surface in production. I need a close, methodical audit of the file—look at the schema compliance, catch any malformed nodes or attributes, resolve namespace inconsistencies, and ensure all values pass proper validation. Once the analysis is complete, please deliver the corrected XML along with a concise change log so I can see exactly what was adjusted and why. If you plan to use tools such as XSD validation, XPath, or automated linting, feel free—just make sure the final file is 100 % error-free and loads cleanly in any standards-compliant parser. Turnaround is important to me, but correctness is paramount. Let me know your expected timeline when you bid, and tell me briefly how you tackle XML validation so I know we’re on the same wavelength.
