Method Detail

isValidNameStart

public static boolean isValidNameStart(int c)

Determine whether the supplied character is a valid first character in an XML Name. The first character in an XML name is more restrictive than the remaining characters.

Parameters:

c - the character

Returns:

true if the character is valid for an XML Name's first character

isValidNcNameStart

public static boolean isValidNcNameStart(int c)

Determine whether the supplied character is a valid first character in an XML NCName. The first character in an XML NCName is more restrictive than the remaining characters.

Parameters:

c - the character

Returns:

true if the character is valid for an XML NCName's first character

isValidName

public static boolean isValidName(int c)

Determine whether the supplied character is a valid non-first character in an XML Name. The first character in an XML name is more restrictive than the remaining characters.

Parameters:

c - the character

Returns:

true if the character is valid character in an XML Name

isValidNcName

public static boolean isValidNcName(int c)

Determine whether the supplied character is a valid non-first character in an XML NCName. The first character in an XML NCName is more restrictive than the remaining characters.

Parameters:

c - the character

Returns:

true if the character is valid character in an XML NCName

isValidPubid

public static boolean isValidPubid(int c)

Determine whether the supplied character is a valid character in an XML Pubid.

Parameters:

c - the character

Returns:

true if the character is valid character in an XML Pubid

isValid

public static boolean isValid(int c)

Determine whether the supplied character is a valid character in XML.

Parameters:

c - the character

Returns:

true if the character is valid character in XML

isValidContent

public static boolean isValidContent(int c)

Determine whether the supplied character is a valid character in XML content

Parameters:

c - the character

Returns:

true if the character is valid character in XML content

isValidSpace

public static boolean isValidSpace(int c)

Determine whether the supplied character is a valid whitespace character in XML

Parameters:

c - the character

Returns:

true if the character is valid whitespace character in XML

isValidName

public static boolean isValidName(String name)

Determine if the supplied name is a valid XML Name.

Parameters:

name - the string being checked

Returns:

true if the supplied name is indeed a valid XML Name, or false otherwise
