[XB] BB Code Processing Rules 1.0.0

Create configurable rules to transform BB Code before content is stored or immediately before it is displayed.

This add-on provides an ordered BB Code processing system with per-rule content targeting, flexible transformations, and preprocessing or postprocessing modes.

---

Features:​

• Optional Processing Groups: Organize rules into ordered groups when needed, or keep rules ungrouped.
• Per-Rule Processing Mode: Choose preprocessing or postprocessing independently for each rule.
• Per-Rule Content Types: Apply rules to selected content types or leave the selection empty to process all supported content.
• Preprocessing: Transform BB Code before XenForo prepares and stores the message.
• Postprocessing: Transform BB Code immediately before rendering without modifying stored content or editor text.
• Multiple Processing Rules: Apply multiple transformations to the same BB Code in the configured order.
• Tag & Option Matching: Target every occurrence of a BB Code tag or only tags with a specific option such as HEADING=1.
• Occurrence Control: Process every matching occurrence or only the first match.
• Wrap Content: Wrap existing content in a BB Code template using the {bbcode} placeholder.
• Prepend & Append: Add parsed BB Code before or after the existing tag content.
• Replace Content or Tag: Replace tag contents or change the BB Code tag while preserving its contents.
• Option Management: Set a BB Code option or apply one only when the original tag has no option.
• Strip or Remove: Remove only the surrounding BB Code tag or remove the tag together with its contents.
• Rule Copying: Create a new rule prefilled with the configuration of an existing rule.
• XML Import & Export: Export processing groups and rules to XML and import them.
• Caching: Keeps processing rules efficiently cached to reduce repeated work and ensure fast processing
• Rule Validation: Prevent invalid BB Code targets, missing configuration, incomplete values, and invalid wrap templates.
