Compare XML files online

Free XML Comparison Tool

XML is everywhere. Config files. API responses. RSS feeds. Last week I edited a pom.xml and broke the build. This tool found the missing <version>. Now I compare XML like checking expiry dates.

Why XML Demands Precision

Tags must close. Always. I once wrote <note>Hello</Note>. The tool highlighted the case mismatch. The parser failed. I felt foolish. Now I know.

Do you use attributes? I changed <book id="101"> to <book ID="101">. The tool showed the change. The system rejected it. Case sensitivity matters.

Real XML Errors

Case 1: A <!-- comment --> was deleted. The tool showed the missing line. Case 2: An unescaped & in <title>Rock & Roll</title>. The tool flagged it. Validation passed.

The tool highlights the line. Parsers choked. I fixed it. Crisis over.

For Integration Teams

We handle SOAP APIs. 500+ XML schemas. The tool compares WSDL files. Last month a <xs:element> type changed from string to int. The tool showed the line. Clients stayed happy.

Pro tip: Compare namespaces. I found a missing xmlns:xsi. The tool highlighted the line. Validation errors gone.

XML’s Strictness

This tool won’t fix your CDATA sections. But it shows where you added an extra </div>. Use it before sending XML to partners. They’ll think you’re perfect.

Final thought: XML is strict. This tool is stricter. Perfect match.
