Enclosing class:

AbstractTextSerializer

public static class AbstractTextSerializer.NamespaceAsAttributes
extends AbstractXMLPipe

A pipe that ensures that all namespace prefixes are also present as 'xmlns:' attributes. This used to circumvent Xalan's serialization behaviour which is to ignore namespaces if they're not present as 'xmlns:xxx' attributes.

Method Detail

startDocument

public void startDocument()
                   throws SAXException

Description copied from class: AbstractXMLPipe

Receive notification of the beginning of a document.

Specified by:

startDocument in interface ContentHandler

Overrides:

startDocument in class AbstractXMLPipe

Throws:

SAXException

startPrefixMapping

public void startPrefixMapping(String prefix,
                               String uri)
                        throws SAXException

Track mappings to be able to add xmlns: attributes in startElement().

Specified by:

startPrefixMapping in interface ContentHandler

Overrides:

startPrefixMapping in class AbstractXMLPipe

Parameters:

prefix - The Namespace prefix being declared.

uri - The Namespace URI the prefix is mapped to.

Throws:

SAXException

startElement

public void startElement(String eltUri,
                         String eltLocalName,
                         String eltQName,
                         Attributes attrs)
                  throws SAXException

Ensure all namespace declarations are present as xmlns: attributes and add those needed before calling superclass. This is a workaround for a Xalan bug (at least in version 2.0.1) : org.apache.xalan.serialize.SerializerToXML ignores start/endPrefixMapping().

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class AbstractXMLPipe

Parameters:

eltUri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

eltLocalName - The local name (without prefix), or the empty string if Namespace processing is not being performed.

eltQName - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

attrs - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.

Throws:

SAXException

endElement

public void endElement(String eltUri,
                       String eltLocalName,
                       String eltQName)
                throws SAXException

Receive notification of the end of an element. Try to restore the element qName.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class AbstractXMLPipe

Parameters:

eltUri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

eltLocalName - The local name (without prefix), or the empty string if Namespace processing is not being performed.

eltQName - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

Throws:

SAXException

endPrefixMapping

public void endPrefixMapping(String prefix)
                      throws SAXException

End the scope of a prefix-URI mapping: remove entry from mapping tables.

Specified by:

endPrefixMapping in interface ContentHandler

Overrides:

endPrefixMapping in class AbstractXMLPipe

Parameters:

prefix - The prefix that was being mapping.

Throws:

SAXException

endDocument

public void endDocument()
                 throws SAXException

Description copied from class: AbstractXMLPipe

Receive notification of the end of a document.

Specified by:

endDocument in interface ContentHandler

Overrides:

endDocument in class AbstractXMLPipe

Throws:

SAXException
