Method Summary

void	addSelector(ElementSelector selector)
boolean	couldSelectElement(java.lang.String path, int startIndex, java.lang.String uri, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes attrs) Give all child selectors a chance to look at it.
void	processCharacters(java.lang.String path, char[] ch, int start, int length) subclasses can override this to select based on contents of cData.
void	processChildElement(java.lang.String childPath, ElementSelector.ElementData parentElement, java.lang.String uri, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes attrs) subclasses can override this to select parent tag based on contents of child tags.
void	processChildElement(java.lang.String childPath, int startedAt, java.lang.String uri, java.lang.String localName, java.lang.String qName, org.xml.sax.Attributes attrs) This method is used to determine if the presence of a certain child tag should cause the parent (or ancestor tag) to be selected too.
boolean	shouldSelectElement(int startIndex) This method is called by SAXDeleteFilter to determine if this ElementSelector has any Elements that start at the given index and that should be selected.
