Description copied from class: org.xml.sax.helpers.DefaultHandler

Receive notification of the start of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the start of each element (such as allocating a new tree node or writing output to a file).

Overrides:

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

Following copied from class: org.xml.sax.helpers.DefaultHandler

Parameters:

name - The element type name.

attributes - The specified or defaulted attributes.

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

Description copied from class: org.xml.sax.helpers.DefaultHandler

Receive notification of the end of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each element (such as finalising a tree node or writing output to a file).

Overrides:

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

Following copied from class: org.xml.sax.helpers.DefaultHandler

Parameters:

name - The element type name.

attributes - The specified or defaulted attributes.
