public enum ParseError : Error

Enums used to delineate the different kinds of parse errors that may be encountered during HTML unescaping. See https://www.w3.org/TR/html5/syntax.html#tokenizing-character-references for an explanation of the different parse errors.

  • “If that number is one of the numbers in the first column of the following table, then this is a parse error.”

    Declaration

    Swift

    case DeprecatedNumericReference(String)

  • “[I]f the number is in the range 0x0001 to 0x0008, 0x000D to 0x001F, 0x007F to 0x009F, 0xFDD0 to 0xFDEF, or is one of 0x000B, 0xFFFE, 0xFFFF, 0x1FFFE, 0x1FFFF, 0x2FFFE, 0x2FFFF, 0x3FFFE, 0x3FFFF, 0x4FFFE, 0x4FFFF, 0x5FFFE, 0x5FFFF, 0x6FFFE, 0x6FFFF, 0x7FFFE, 0x7FFFF, 0x8FFFE, 0x8FFFF, 0x9FFFE, 0x9FFFF, 0xAFFFE, 0xAFFFF, 0xBFFFE, 0xBFFFF, 0xCFFFE, 0xCFFFF, 0xDFFFE, 0xDFFFF, 0xEFFFE, 0xEFFFF, 0xFFFFE, 0xFFFFF, 0x10FFFE, or 0x10FFFF, then this is a parse error.”

    Declaration

    Swift

    case DisallowedNumericReference(String)

  • This should NEVER be hit in code execution. If this error is thrown, then decoder has faulty logic

    Declaration

    Swift

    case IllegalArgument(String)

  • “[I]f the characters after the U+0026 AMPERSAND character (&) consist of a sequence of one or more alphanumeric ASCII characters followed by a U+003B SEMICOLON character (;), then this is a parse error.”

    Declaration

    Swift

    case InvalidNamedReference(String)

  • “If no characters match the range, then don’t consume any characters (and unconsume the U+0023 NUMBER SIGN character and, if appropriate, the X character). This is a parse error; nothing is returned.”

    Declaration

    Swift

    case MalformedNumericReference(String)

  • “[I]f the next character is a U+003B SEMICOLON, consume that too. If it isn’t, there is a parse error.”

    Declaration

    Swift

    case MissingSemicolon(String)

  • “[I]f the number is in the range 0xD800 to 0xDFFF or is greater than 0x10FFFF, then this is a parse error.”

    Declaration

    Swift

    case OutsideValidUnicodeRange(String)
