Hi Jimmy,
I think the last question goes to the OpenOffice team.
Here is my base class of the filter, it uses a lot of wrapper classes to
handle the javax.xml.transform.sax.* and the com.sun.star.xml.sax.*
classes.
package dk.abj.openoffice.filter;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.xml.transform.sax.SAXResult;
import javax.xml.transform.sax.SAXSource;
import javax.xml.transform.sax.SAXTransformerFactory;
import javax.xml.transform.sax.TransformerHandler;
import javax.xml.transform.stream.StreamResult;
import org.xml.sax.InputSource;
import com.sun.star.beans.PropertyValue;
import com.sun.star.io.XOutputStream;
import com.sun.star.lang.IllegalArgumentException;
import com.sun.star.lib.uno.adapter.XInputStreamToInputStreamAdapter;
import com.sun.star.lib.uno.adapter.XOutputStreamToOutputStreamAdapter;
import com.sun.star.uno.AnyConverter;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.xml.sax.XDocumentHandler;
import dk.abj.openoffice.xml.SAXAdapter;
import dk.abj.openoffice.xml.XContentHandlerToContentHandlerAdapter;
public class DXF2CALCTemplateGeneratorFilter extends
XContentHandlerToContentHandlerAdapter implements
com.sun.star.xml.XImportFilter,
com.sun.star.xml.XExportFilter { public final static String SERVICE =
"dk.abj.openoffice.filter.DXF2CALCTemplateGeneratorFilter";
public static final String EXPORT_XSL_STYLESHEET =
"templates/templategenerator/export.xsl";
public static final String IMPORT_XSL_STYLESHEET =
"templates/templategenerator/import.xsl";
public static final String FILTER_NAME =
"DXF2CALCTemplateGeneratorFilter";
public DXF2CALCTemplateGeneratorFilter() {
super(null);
}
public boolean exporter(PropertyValue[] props, String[] arg1)
throws IllegalArgumentException {
OutputStream out = null;
try {
for (int i = 0; i < props.length; i++) {
if
(props[i].Name.equals("OutputStream")) { XOutputStream io =
(XOutputStream) UnoRuntime .queryInterface(
com.sun.star.io.XOutputStream.class,
props[i].Value);
out = new
XOutputStreamToOutputStreamAdapter(io); }
}
SAXTransformerFactory factory =
(SAXTransformerFactory) SAXTransformerFactory .newInstance();
InputStream in =
this.getClass().getClassLoader() .getResourceAsStream(EXPORT_XSL_STYLESHEET);
SAXSource src = new SAXSource(new
InputSource(in));
// setup the transformer with the stylessheet
TransformerHandler f =
factory.newTransformerHandler(src);
// setup the output-stream
f.setResult(new StreamResult(out));
// put the transformer as sax-event receiver
into the chain this.handler = f;
} catch (Exception e) {
e.printStackTrace();
if (out != null) {
try {
out.close();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
throw new
IllegalArgumentException(e.toString()); }
// all done
return true;
}
public boolean importer(PropertyValue[] props, XDocumentHandler
handler, String[] arg2) throws IllegalArgumentException {
try {
InputStream documentInputStream = null;
String filename = null;
// get the filter settings and the input
// from the mediadescriptor
for (int i = 0; i < props.length; i++) {
if (props[i].Name.equals("FileName")) {
filename =
AnyConverter.toString(props[i].Value); } else if
(props[i].Name.equals("InputStream")) { com.sun.star.io.XInputStream io
= (com.sun.star.io.XInputStream)
UnoRuntime .queryInterface(com.sun.star.io.XInputStream.class,
props[i].Value);
documentInputStream = new
XInputStreamToInputStreamAdapter( io);
}
}
if (documentInputStream == null) {
documentInputStream = new
FileInputStream(filename); }
InputStream in =
this.getClass().getClassLoader() .getResourceAsStream(IMPORT_XSL_STYLESHEET);
SAXSource src = new SAXSource(new
InputSource(in));
// create a XSLTTransformer and set the template
SAXTransformerFactory factory =
(SAXTransformerFactory) SAXTransformerFactory .newInstance();
TransformerHandler f =
factory.newTransformerHandler(src);
// We wrap the openoffice contenthandler to
// a SAXContentHandler and
// put the the transformer in the chain
SAXAdapter saxadapter = new SAXAdapter(handler);
// invoke the transformation
f.getTransformer().transform(
new SAXSource(new
InputSource(documentInputStream)), new SAXResult(saxadapter));
} catch (Exception e) {
e.printStackTrace();
throw new
IllegalArgumentException(e.toString()); }
return true;
}
}
The rest of the needed code is to large for the a mailing-list or a
snipped, but the project is free available and you can get the
sources here:
http://abj.dk/dxf2calc/download/index.html
there you can find all java sources and xcu files.
Best Regards,
Simon
