Method Detail

normalize

public static java.lang.String normalize(java.lang.String publicId)

Normalize a public identifier.

Public identifiers must be normalized according to the following rules before comparisons between them can be made:

• Whitespace characters are normalized to spaces (e.g., line feeds, tabs, etc. become spaces).
• Leading and trailing whitespace is removed.
• Multiple internal whitespaces are normalized to a single space.

This method is declared static so that other classes can use it directly.

Parameters:

publicId - The unnormalized public identifier.

Returns:

The normalized identifier.

encodeURN

public static java.lang.String encodeURN(java.lang.String publicId)

Encode a public identifier as a "publicid" URN.

This method is declared static so that other classes can use it directly.

Parameters:

publicId - The unnormalized public identifier.

Returns:

The normalized identifier.

decodeURN

public static java.lang.String decodeURN(java.lang.String urn)

Decode a "publicid" URN into a public identifier.

This method is declared static so that other classes can use it directly.

Parameters:

urn - The urn:publicid: URN

Returns:

The normalized identifier.
