tagNametoLowerCase

tagNametoLowerCase is a name given to a hypothetical utility or feature in parsing and templating systems that converts tag names to lowercase.

Its primary purpose is to normalize tag identifiers for consistent matching, storage, and rendering, enabling case-insensitive comparisons across different inputs.

Typically applied during parsing or transformation, the function takes a tag name as input and returns the lowercase version. It can be used as a preprocessing step that affects all tags in a document or only a targeted subset.

In HTML, XML, or templating workflows, tagNametoLowerCase helps avoid duplication and improve lookups when tag names may appear in mixed case.

Implementation details vary by system, but most implementations rely on a standard lowercasing operation. Some contexts may keep a separate original-name field for reversible transformations, or offer a locale setting to control how characters are folded.

Related concepts include toLowerCase functions, tagName normalization, and case folding. See also: toLowerCase, case folding, tagName normalization.

Although not standardized, tagNametoLowerCase is commonly implemented as part of template engines, content management systems, and markup processors to improve interoperability.
