Method Detail

createQName

@Deprecated
public static QName createQName(String namespaceUri,
                                            String localPart,
                                            String prefix)

Deprecated. in favor of QName.QName(String, String, String)

Creates a new QName with the given parameters. Sets the prefix if possible, i.e. if the QName(String, String, String) constructor can be found. If this constructor is not available (as is the case on older implementations of JAX-RPC), the prefix is ignored.

Parameters:

namespaceUri - namespace URI of the QName

localPart - local part of the QName

prefix - prefix of the QName. May be ignored.

Returns:

the created QName

See Also:

QName.QName(String,String,String)

getPrefix

@Deprecated
public static String getPrefix(QName qName)

Deprecated. in favor of QName.getPrefix()

Returns the prefix of the given QName. Returns the prefix if available, i.e. if the QName.getPrefix() method can be found. If this method is not available (as is the case on older implementations of JAX-RPC), an empty string is returned.

Parameters:

qName - the QName to return the prefix from

Returns:

the prefix, if available, or an empty string

See Also:

QName.getPrefix()

validateQName

public static boolean validateQName(String text)

Validates the given String as a QName

Parameters:

text - the qualified name

Returns:

true if valid, false otherwise

getQNameForNode

public static QName getQNameForNode(Node node)

Returns the qualified name of the given DOM Node.

Parameters:

node - the node

Returns:

the qualified name of the node

toQualifiedName

public static String toQualifiedName(QName qName)

Convert a QName to a qualified name, as used by DOM and SAX. The returned string has a format of prefix:localName if the prefix is set, or just localName if not.

Parameters:

qName - the QName

Returns:

the qualified name

toQName

public static QName toQName(String namespaceUri,
                            String qualifiedName)

Convert a namespace URI and DOM or SAX qualified name to a QName. The qualified name can have the form prefix:localname or localName.

Parameters:

namespaceUri - the namespace URI

qualifiedName - the qualified name

Returns:

a QName

parseQNameString

public static QName parseQNameString(String qNameString)

Parse the given qualified name string into a QName. Expects the syntax localPart, {namespace}localPart, or {namespace}prefix:localPart. This format resembles the toString() representation of QName itself, but allows for prefixes to be specified as well.

Returns:

a corresponding QName instance

Throws:

IllegalArgumentException - when the given string is null or empty.
