Method Detail

isName

public static boolean isName(java.lang.String value)

Returns true if the value is a legal XML name.

Parameters:

value - the string being tested

isUnqualifiedName

public static boolean isUnqualifiedName(java.lang.String value)

Returns true if the value is a legal "unqualified" XML name, as defined in the XML Namespaces proposed recommendation. These are normal XML names, except that they may not contain a "colon" character.

Parameters:

value - the string being tested

isQualifiedName

public static boolean isQualifiedName(java.lang.String value)

Returns true if the value is a legal "qualified" XML name, as defined in the XML Namespaces proposed recommendation. Qualified names are composed of an optional prefix (an unqualified name), followed by a colon, and a required "local part" (an unqualified name). Prefixes are declared, and correspond to particular URIs which scope the "local part" of the name. (This method cannot check whether the prefix of a name has been declared.)

Parameters:

value - the string being tested

isNmtoken

public static boolean isNmtoken(java.lang.String token)

This method returns true if the identifier is a "name token" as defined in the XML specification. Like names, these may only contain "name characters"; however, they do not need to have letters as their initial characters. Attribute values defined to be of type NMTOKEN(S) must satisfy this predicate.

Parameters:

token - the string being tested

isNCNmtoken

public static boolean isNCNmtoken(java.lang.String token)

This method returns true if the identifier is a "name token" as defined by the XML Namespaces proposed recommendation. These are like XML "name tokens" but they may not contain the "colon" character.

Parameters:

token - the string being tested
