 sax.DataUnformatFilter
| DataUnformatFilter | | public class DataUnformatFilter extends XMLFilterBase (Code) | | Filter for removing formatting from data- or field-oriented XML.
Code and comments adapted from DataWriter-0.2, written
by David Megginson and released into the public domain,
without warranty.
This filter removes leading and trailing whitespace from
field-oriented XML without mixed content. Note that this class will
likely not yield appropriate results for document-oriented XML like
XHTML pages, which mix character data and elements together.

| Method Summary | |
| public void | characters(char ch, int start, int length)
Filter a character data event. | | protected void | clearWhitespace()
Discards saved whitespace. | | protected void | emitWhitespace()
Passes saved whitespace down the filter chain. | | public void | endElement(String uri, String localName, String qName)
Filter an end element event. | | public void | ignorableWhitespace(char ch, int start, int length)
Filter an ignorable whitespace event. | | public void | processingInstruction(String target, String data)
Filter a processing instruction event. | | public void | reset()
Reset the filter so that it can be reused. | | protected void | saveWhitespace(char[] ch, int start, int length)
Saves trailing whitespace. | | public void | startDocument()
Filter a start document event. | | public void | startElement(String uri, String localName, String qName, Attributes atts)
Filter a start element event. |
| DataUnformatFilter | | public DataUnformatFilter()(Code) | | Create a new filter.
|
| DataUnformatFilter | | public DataUnformatFilter(XMLReader xmlreader)(Code) | | Create a new filter.
Use the XMLReader provided as the source of events.
Parameters:
xmlreader - The parent in the filter chain. |
| characters | | public void characters(char ch, int start, int length) throws SAXException(Code) | | Filter a character data event.
Parameters:
ch - The characters to write.
Parameters:
start - The starting position in the array.
Parameters:
length - The number of characters to use.
exception:
org.xml.sax.SAXException - If a filterfurther down the chain raises an exception.

| clearWhitespace | | protected void clearWhitespace()(Code) | | Discards saved whitespace.
|
| emitWhitespace | | protected void emitWhitespace() throws SAXException(Code) | | Passes saved whitespace down the filter chain.
|
| ignorableWhitespace | | public void ignorableWhitespace(char ch, int start, int length) throws SAXException(Code) | | Filter an ignorable whitespace event.
Parameters:
ch - The array of characters to write.
Parameters:
start - The starting position in the array.
Parameters:
length - The number of characters to write.
exception:
org.xml.sax.SAXException - If a filterfurther down the chain raises an exception.

| reset | | public void reset()(Code) | | Reset the filter so that it can be reused.
This method is especially useful if the filter failed
with an exception the last time through.
|
| saveWhitespace | | protected void saveWhitespace(char[] ch, int start, int length)(Code) | | Saves trailing whitespace.
