Well-formed XML
Unclosed tags, invalid nesting, broken entities and document-level parse errors.
XML FEED VALIDATOR
XML feed validator for product catalog structure and data quality
FeedScore separates syntax blockers from product-data problems. That makes it clear whether the file cannot be parsed, individual items are malformed, or the catalog is technically valid but commercially incomplete.

AUDIT SCOPE
What the XML feed validator checks
Encoding and namespaces
Encoding declarations and the namespaces required by the chosen feed structure.
Product structure
Consistent item or entry nodes and repeated attribute patterns.
Required values
Empty, missing or malformed core product fields.
IDs and URLs
Duplicate identifiers plus invalid or inaccessible product and image links.
Catalog quality
Content, identifier, price, availability and taxonomy coverage after parsing.
ISSUE PRIORITY
XML errors and the right response
Fix blockers first, then catalog-wide patterns, and leave isolated optimization opportunities for last.

HOW IT WORKS
From raw feed to prioritized fixes
Fetch the XML
FeedScore reads the public URL and records access, status and file-level signals.
Parse every item
The validator checks structure first, then evaluates values product by product.
Group root causes
The report combines repeated failures so you can fix the export logic once.
IMPORTANT DISTINCTION
Well formed does not mean feed ready
A file can be perfect XML and still contain missing GTINs, weak titles, invalid prices or broken image URLs. FeedScore combines XML validation with catalog-level commerce checks.
FAQ
Questions about this check
Does the validator support RSS and Atom product feeds?+
The planned parser covers common XML product-feed structures, including RSS-style item lists and Atom-style entries. Final format coverage will be documented when the production parser is connected.
Can a valid XML feed still fail in Merchant Center?+
Yes. XML syntax is only one layer. Attribute requirements, values, website data, account settings and policies can still cause warnings or disapprovals.
Will the report show the affected products?+
Yes. The full report is designed to list issue counts and export the product identifiers or rows affected by each check.
Do you modify the XML file?+
No. FeedScore analyzes the source and explains what to fix. It does not rewrite or upload your feed.
METHODOLOGY & SOURCES
Built around documented feed requirements
Our public guidance is checked against first-party documentation. FeedScore adds independent data-quality checks and does not represent a platform approval decision.
