Subject Re: Problem using attributes with <xsl:value-of select=""/>
Date Tue, 24 Nov 2009 02:28:38 GMT

I could use assistance here.  Given an xml such as:

<report reportId="123">
   <animal>cat</animal>
</report>

My embedded FOP transformation is handling elements but not attributes. 
Here is the code as a Nabble attachment:  
http://old.nabble.com/file/p26489602/attributetest.zip attributetest.zip  --
if you have Maven on your machine, "mvn clean install exec:exec" will
quickly and easily show the problem.  Here is the code within the
attachment:

public class AttributeTest {
    ....
    
    private void run() {
       try {
          // works fine -- both animal element and reportId attribute in pdf
          URL fileURL = getClass().getClassLoader().getResource("attr.xml");
          Source rptSource = new StreamSource(fileURL.toString());
          OutputStream outStream = new
java.io.FileOutputStream("1pdfdirect.pdf");
   
          FopFactory fopFactory = FopFactory.newInstance();
          Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, outStream);
          Result res = new SAXResult(fop.getDefaultHandler());
   
          URL stylesheetURL =
getClass().getClassLoader().getResource("AttributeTest.xsl");
          TransformerFactory factory = TransformerFactory.newInstance();
          Transformer t = factory.newTransformer(new
StreamSource(stylesheetURL.toString()));
          t.transform(rptSource, res);
          outStream.close();
          
          // does not work -- has animal element but not reportId attribute
in pdf
          Source rptSource2 = new SAXSource(new ReportXMLBuilder(), new
EmptyInputSource());
          OutputStream outStream2 = new
java.io.FileOutputStream("2pdfViaReader.pdf");

          Fop fop2 = fopFactory.newFop(MimeConstants.MIME_PDF, outStream2);
          Result res2 = new SAXResult(fop2.getDefaultHandler());
          t.transform(rptSource2, res2);
          outStream2.close();
          
          // but oddly, this *does* work -- keeps reportId attribute
          Source rptSource3 = new SAXSource(new ReportXMLBuilder(), new
EmptyInputSource());
          Transformer t2 = factory.newTransformer();  
          Result res3 = new StreamResult("3xmloutput.xml"); // has reportId
attribute
          t2.transform(rptSource3, res3);
          
       } catch (Exception e) {
          e.printStackTrace(System.out);
       }
    }

    // AbstractXMLBuilder is here: http://tinyurl.com/ye4c39h
    public static class ReportXMLBuilder extends AbstractXMLBuilder {
       public void parse(InputSource input) throws IOException, SAXException
{
           handler.startDocument();
           AttributesImpl atts = new AttributesImpl();
           atts.addAttribute("", "", "reportId", "", "123");        
           handler.startElement("report", atts);
           handler.element("animal", "cat");
           handler.endElement("report");
           handler.endDocument();        
       }
    }
  
...
}

Can anyone see what I'm doing wrong?

Thanks,
Glen
