Cleaning Up Messy HTML Before Saving It in Evolution CMS

Messy HTML is one of those problems that keeps returning if the project only patches symptoms. Copy-paste from office tools, external editors, or inconsistent manual markup can slowly turn content fields into a maintenance burden.

The source note pointed to a dedicated cleaner such as Jevix, which is still the right instinct. Once content includes unreliable HTML, a real sanitation layer is safer than hand-written replacements.

Why ad hoc cleanup is risky

• Regex-only cleanup often breaks valid markup while missing invalid edge cases.
• Teams start stacking one-off fixes for every new content anomaly.
• Unsafe HTML may pass through unchanged if the cleanup rules are too narrow.

Better approach

Use a proper HTML-cleaning step before saving or rendering content. Define which tags, attributes, and structures are allowed, and normalize the rest. That gives editors cleaner output and developers fewer rendering surprises.

Where to apply it

Depending on the project, cleanup can happen on save, in a preprocessing snippet, or in a moderation/import pipeline. The earlier the cleanup happens, the less broken markup spreads through the site.

For long-lived Evo sites, content hygiene is not optional. A reliable sanitizer is part of the editing stack, not just a rescue tool.
