XML Compare Tool — Format & Diff XML Workspace
Format XML via DOMParser — proxies xml-formatter; pair with text-diff-checker for compare
How to Use This Tool
- Pretty print first XML version in proxied xml-formatter.
- Copy formatted output to staging buffer.
- Pretty print second version with same indent policy.
- Open text-diff-checker — paste before and after panels.
- Run compare for added, removed, unchanged line highlights.
- Fix parse errors in formatter before diffing invalid XML.
About This Tool
Config drift between staging and production XML, SAML metadata version bumps, and Maven POM dependency changes need side-by-side comparison after consistent formatting — otherwise whitespace-only diffs hide real element changes. VSPIC xml-compare-tool maps to type proxy, slug xml-formatter in missing-tools-handlers.generated.ts — DOMParser validation and pretty print, not a dedicated two-pane XML semantic diff on this slug today.
Pretty-print both XML versions here, then paste into text-diff-checker for line-level LCS diff. Honest documentation avoids implying automatic compare UI on formatter proxy alone.
Common use cases
- •Inspect HTTP headers and user-agent strings
- •Analyze email headers for phishing investigation
- •Generate strong passwords for staging environments
Why use VSPIC for ?
- Consistent indent before text diff reduces noise.
- DOMParser catches syntax breaks before compare.
- Client-side formatter — internal configs stay local.
- text-diff-checker sibling provides real compare UI.
- Minify mode for size-only comparison tickets.
- Honest proxy limitation documentation.
XML compare workflow
Normalize indent on both documents, then line diff. Attribute reordering may show false positives if serializer order differs — pretty print both through same formatter proxy first.
Proxy to xml-formatter
xml-compare-tool handler is type proxy, slug xml-formatter.
Use text-diff-checker
text-diff-checker renders LCS line diff client-side — canonical compare UI after formatting XML here.
Relationship to xml-viewer
xml-viewer also proxies formatter for exploration — compare workflow chains formatter then diff.
SAML metadata version bumps
Format old and new metadata, diff lines, focus on Certificate and Endpoint element changes.
CI XML diff alternatives
xmldiff libraries and diff -u on formatted exports suit batch pipelines.
Client-side privacy
Federation XML with entity IDs stays local on formatter path.
Minify both for byte compare
When question is transport size not element drift, minify both versions and compare character counts.
Future semantic XML diff handler
Registry may add tree-aware compare client.
Important notes & limitations
- No two-pane XML compare on this slug — formatter proxy.
- Semantic diff ignores attribute order unless formatted consistently.
- text-diff-checker is line-based — not XPath-aware.
- Very large XML may need external diff tools.
- Not XSD-aware comparison.
