Method Details

replaceEntities

public static String replaceEntities(String input)

Replaces all known HTML named entities in the input string with their numeric character references. XML entities (&, <, >, ', ") are left as-is since the XML parser handles them natively.

This is a single-pass O(n) implementation that scans for & characters and looks up the entity name in a hash map.

Parameters:

input - the input string potentially containing HTML named entities

Returns:

the string with HTML named entities replaced by numeric character references
