Description

[0001] FIELD OF THE INVENTION The present invention relates to an HTML template rendering language tag parsing engine based on a content management system data model, which is suitable for the demand of dynamically generating HTML content in a website content management system (CMS). Background Art

[0002] With the rapid development of Internet technology, website content management systems (CMS) have been widely used in various websites. These systems usually need to dynamically generate HTML content to meet the needs of different users. Traditional HTML content generation methods often rely on server-side scripting languages ​​(such as PHP, Python, Java, etc.) for template rendering. Although this method is effective, it has certain limitations in flexibility and scalability.

[0003] The existing HTML content generation methods have the following shortcomings:

[0004] Lack of flexibility: Traditional template rendering methods usually require the template structure to be defined in advance, which makes it difficult to quickly adjust and expand for complex and changing content requirements.

[0005] Low development efficiency: Every modification to the content generation logic requires rewriting and debugging the backend code, increasing development and maintenance costs.

[0006] Security issues: When generating HTML content, if there is no strict input validation and content filtering mechanism, it is easy to cause security issues such as XSS (cross-site scripting attack).

[0007] Poor user experience: Dynamically generated content that loads slowly can affect the user experience, especially on mobile devices.
