Class MarcXmlReader

java.lang.Object

org.marc4j.MarcXmlReader

All Implemented Interfaces:

MarcReader

public class MarcXmlReader
extends Object
implements MarcReader

An iterator over a collection of MARC records in MARCXML format.

Basic usage:

 InputStream input = new FileInputStream("file.xml");
 MarcReader reader = new MarcXmlReader(input);
 while (reader.hasNext()) {
   Record record = reader.next();
   // Process record
 }
 

Check the org.marc4j.marc package for examples about the use of the Record object model.

You can also pre-process the source to create MARC XML from a different format using an XSLT stylesheet. The following example creates an iterator over a collection of MARC records in MARC XML format from a MODS source and outputs MARC records in MARC21 format:

 InputStream in = new FileInputStream("modsfile.xml");

 MarcStreamWriter writer = new MarcStreamWriter(System.out, Constants.MARC8);
 MarcXmlReader reader =
   new MarcXmlReader(in, "http://www.loc.gov/standards/marcxml/xslt/MODS2MARC21slim.xsl");
 while (reader.hasNext()) {
   Record record = reader.next();
   writer.write(record);
 }
 writer.close();

Constructor Detail

MarcXmlReader

public MarcXmlReader(InputStream input)

Constructs an instance with the specified input stream.

Parameters:

input - the input stream

MarcXmlReader

public MarcXmlReader(InputSource input)

Constructs an instance with the specified input source.

Parameters:

input - the input source

MarcXmlReader

public MarcXmlReader(InputStream input,
             String stylesheetUrl)

Constructs an instance with the specified input stream and stylesheet location. The stylesheet is used to transform the source file and should produce valid MARC XML records. The result is then used to create Record objects.

Parameters:

input - the input stream

stylesheetUrl - the stylesheet location

MarcXmlReader

public MarcXmlReader(InputStream input,
             Source stylesheet)

Constructs an instance with the specified input stream and stylesheet source. The stylesheet is used to transform the source file and should produce valid MARCXML records. The result is then used to create Record objects.

Parameters:

input - the input stream

stylesheet - the stylesheet source

MarcXmlReader

public MarcXmlReader(InputSource input,
             Source stylesheet)

Constructs an instance with the specified input source and stylesheet source. The stylesheet is used to transform the source file and should produce valid MARCXML records. The result is then used to create Record objects.

Parameters:

input - the input source

stylesheet - the stylesheet source

MarcXmlReader

public MarcXmlReader(InputStream input,
             TransformerHandler th)

Constructs an instance with the specified input stream and transformer handler. The TransformerHandler is used to transform the source file and should produce valid MARCXML records. The result is then used to create Record objects. A TransformerHandler can be obtained from a SAXTransformerFactory with either a Source or Templates object.

Parameters:

input - the input stream

th - the transformation content handler

MarcXmlReader

public MarcXmlReader(InputSource input,
             TransformerHandler th)

Constructs an instance with the specified input source and transformer handler. The TransformerHandler is used to transform the source file and should produce valid MARCXML records. The result is then used to create Record objects. A TransformerHandler can be obtained from a SAXTransformerFactory with either a Source or Templates object.

Parameters:

input - the input source

th - the transformation content handler

Method Detail

hasNext

public boolean hasNext()

Returns true if the iteration has more records, false otherwise.

Specified by:

hasNext in interface MarcReader

Returns:

boolean - true if the iteration has more records, false otherwise

next

public Record next()

Returns the next record in the iteration.

Specified by:

next in interface MarcReader

Returns:

Record - the record object
