getTxn

public Collection<TransactionOperation> getTxn()

get the parsed transaction

Returns:

the parsed transaction

startDocument

public void startDocument()
                   throws SAXException

Description copied from interface: SimpleSAXListener

Notifies the listener that the parser has started parsing.

startDocument in interface SimpleSAXListener

Overrides:

startDocument in class SimpleSAXAdapter

Throws:

SAXException

startTag

public void startTag(String tagName,
 Map<String,String> atts,
 String text)
              throws SAXException

Specified by:

startTag in interface SimpleSAXListener

Overrides:

startTag in class SimpleSAXAdapter

Parameters:

tagName - The tag name.

atts - A map containing key-value-pairs representing the attributes that were found in the start tag.

text - The text immediately following the start tag, or an empty string if the start tag was followed by a nested start tag or if no text (other than whitespace) was found between start- and end tag.

Throws:

SAXException

endTag

public void endTag(String tagName)
            throws SAXException

Description copied from interface: SimpleSAXListener
