                      boolean isCrop)

Creates a new instance of LangFileParser

Method Detail

startDocument

public void startDocument()
                   throws org.xml.sax.SAXException

Part of SAX XML processing... Called automatically by SAX parser

Throws:

org.xml.sax.SAXException

endDocument

public void endDocument()
                 throws org.xml.sax.SAXException

Part of SAX XML processing... Called automatically by SAX parser

Throws:

org.xml.sax.SAXException

startElement

public void startElement(java.lang.String namespaceURI,
                         java.lang.String lName,
                         java.lang.String qName,
                         org.xml.sax.Attributes attrs)
                  throws org.xml.sax.SAXException

Part of SAX processing that gets called at the when an opening xml tag is encountered. We will filter out the ones we are interested and set the flags for what the character function should grab and where it will be stored.

Throws:

org.xml.sax.SAXException

endElement

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

Part of SAX processing that gets called when an ending xml tag is encountered.

Throws:

org.xml.sax.SAXException

characters

public void characters(char[] buf,
                       int offset,
                       int len)
                throws org.xml.sax.SAXException

Part of SAX processing that gets called to get the contents inside an xml tag. The calls to get the contents may not come in one chunk so we need to accumulate caracter strings until the ending tag then the string can be assumed to be complete.

Throws:

org.xml.sax.SAXException
