Constructor Summary

ElementNamespaceFilter()
An empty constructor that requires the use of setParent before starting I don't think this works.

ElementNamespaceFilter(org.xml.sax.XMLReader parent)
A constructor that takes the parser which will feed it SAX events

Method Summary

void	endElement(java.lang.String uri, java.lang.String localName, java.lang.String qName)
NamespaceRules	getRules() in case you ever need to get the rules out of NamespaceFilter
void	setRules(NamespaceRules newRules) sets up the rules, read in from a config file by RulesLoader or otherwise concocted in Java using the NamespaceRules class.
void	startElement(java.lang.String uri, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes atts) Check at startElement for names which should be qualified.

Method Detail

setRules

public void setRules(NamespaceRules newRules)

sets up the rules, read in from a config file by RulesLoader or otherwise concocted in Java using the NamespaceRules class.

Parameters:

newRules - the set of rules the NamespaceFilter will apply to content

getRules

public NamespaceRules getRules()

in case you ever need to get the rules out of NamespaceFilter

startElement

public void startElement(java.lang.String uri,
                         java.lang.String localName,
                         java.lang.String qName,
                         org.xml.sax.Attributes atts)
                  throws org.xml.sax.SAXException

Check at startElement for names which should be qualified. if the context namespace URI matches a rule, the namespace will be forcibly applied to unqualifed elements.

Overrides:

startElement in class org.xml.sax.helpers.XMLFilterImpl

endElement

public void endElement(java.lang.String uri,
                       java.lang.String localName,
                       java.lang.String qName)
                throws org.xml.sax.SAXException

Overrides:

endElement in class org.xml.sax.helpers.XMLFilterImpl
