public class ElementAnnotNamespaceFilter

extends org.xml.sax.helpers.XMLFilterImpl

A filter which adds context namespace information to unqualified elements according to a set of inclusion or exclusion rules. If no rules are set, all namespaces are annotated.

Context will be indicated in the form of an attribute:

<unqual an:lastNSContext="http://www.example.com xmlns:anlc="http://simonstl.com/ns/namespaces/elements/lastContext/">

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





addAtt
public org.xml.sax.Attributes addAtt(org.xml.sax.Attributes atts)
