Constructor Details

XmlSchemaNamespaceContext

public XmlSchemaNamespaceContext()

Constructs a new XmlSchemaNamespaceContext with the following initial mappings:

• xml -> http://www.w3.org/1999/namespace
• xmlns -> http://www.w3.org/2000/xmlns/

Method Details

getNamespaceURI

public String getNamespaceURI(String prefix)

Specified by:

getNamespaceURI in interface NamespaceContext

See Also:

• NamespaceContext.getNamespaceURI(String)

getPrefix

public String getPrefix(String namespaceUri)

Specified by:

getPrefix in interface NamespaceContext

See Also:

• NamespaceContext.getPrefix(String)

getPrefixes

public Iterator getPrefixes(String namespaceUri)

Specified by:

getPrefixes in interface NamespaceContext

See Also:

• NamespaceContext.getPrefixes(String)

getDeclaredPrefixes

public String[] getDeclaredPrefixes()

Description copied from interface: NamespacePrefixList

Returns the list of currently defined namespace prefixes.

Specified by:

getDeclaredPrefixes in interface NamespacePrefixList

See Also:

• NamespacePrefixList.getDeclaredPrefixes()

addNamespace

public void addNamespace(String prefix,
 String namespaceUri)

Adds a new prefix mapping to the context. The prefix may be an empty string to represent the default namespace, but it cannot be null. The namespace URI can never be empty or null.

Parameters:

prefix - The prefix to represent the namespace URI.

namespaceUri - the namespace URI represented by the prefix.

Throws:

IllegalArgumentException - if the prefix is null, or if the namespace URI is null or empty.

removeNamespace

public void removeNamespace(String prefix)

Removes the most recent prefix-to-namespace mapping for the provided prefix. The prior prefix-to-namespace mapping before it is restored.

Parameters:

prefix - The prefix to remove the current prefix-to-namespace mapping of.

Throws:

IllegalStateException - If there is no current mapping for that prefix.

clear

public void clear()

Clears the given namespace stack, restoring it to the original mappings defined by the constructor.

isRecognizedPrefix

private static boolean isRecognizedPrefix(String prefix)
