                  String selectExpression)
                   throws JRException

Creates the data source by parsing the xml document from the given file. An additional XPath expression specifies the select criteria that produces the nodes (records) for the data source.

Parameters:

document - the document

selectExpression - the XPath select expression

Throws:

JRException - if the data source cannot be created

JaxenXmlDataSource

public JaxenXmlDataSource(InputStream in)
                   throws JRException

Creates the data source by parsing the xml document from the given input stream.

Parameters:

in - the input stream

Throws:

JRException

See Also:

JRXmlDataSource.JRXmlDataSource(Document)

JaxenXmlDataSource

public JaxenXmlDataSource(InputStream in,
                  String selectExpression)
                   throws JRException

Creates the data source by parsing the xml document from the given input stream.

Throws:

JRException

See Also:

JRXmlDataSource.JRXmlDataSource(InputStream), JRXmlDataSource.JRXmlDataSource(Document, String)

JaxenXmlDataSource

public JaxenXmlDataSource(String uri)
                   throws JRException

Creates the data source by parsing the xml document from the given system identifier (URI).

If the system identifier is a URL, it must be full resolved.

Parameters:

uri - the system identifier

Throws:

JRException

See Also:

JRXmlDataSource.JRXmlDataSource(Document)

JaxenXmlDataSource

public JaxenXmlDataSource(String uri,
                  String selectExpression)
                   throws JRException

Creates the data source by parsing the xml document from the given system identifier (URI).

Throws:

JRException

See Also:

JRXmlDataSource.JRXmlDataSource(String), JRXmlDataSource.JRXmlDataSource(Document, String)

JaxenXmlDataSource

public JaxenXmlDataSource(File file)
                   throws JRException

Creates the data source by parsing the xml document from the given file.

Parameters:

file - the file

Throws:

JRException

JRXmlDataSource.JRXmlDataSource(Document)

JaxenXmlDataSource

public JaxenXmlDataSource(File file,
                  String selectExpression)
                   throws JRException

Creates the data source by parsing the xml document from the given file.

Throws:

JRException
