Method Details

parse

public static SequenceIterator parse(StringValue input,
 Map<String,GroundedValue> csvOptions)
                              throws XPathException

Parse an input string containing CSV data into a sequence of ArrayItems (the rows) containing StringValues (the fields), controlled by the passed-in csvOptions. This form constructs a CsvContentHandler using the passed-in csvOptions.

Parameters:

input - the CSV data.

csvOptions - the processed options specified by the caller.

Returns:

the CSV data represented as a sequence of arrays (array(xs:string)*).

Throws:

XPathException - if parsing fails

 CsvContentHandler handler)
                              throws XPathException

Parse an input string containing CSV data into a sequence of ArrayItems (the rows) containing StringValues (the fields), controlled by the passed-in csvOptions. This form requires an existing CsvContentHandler to be used.

Parameters:

input - the CSV data.

csvOptions - the processed options specified by the caller.

handler - the content handler to receive CSV parsing events.

Returns:

the CSV data represents as a sequence of arrays (array(xs:string)*).

Throws:

parseInput

public SequenceIterator parseInput()
                            throws XPathException
