Processing an com.sun.xml.tree.XmlDocument with Xalan

John Gouveia 17 May 2001 16:38:39 -0000

I am new to XML. I am having difficulty accessing the Xalan mailing list and I dont know where else to look. I am sure this topic has been brought up before.

Could anyone please help me with the following code. I have parsed a String into com.sun.xml.tree.XmlDocument;.

I am trying to process this document with Xalan version 1.2.2

When I process the document the following error occurs:

" XSL Error: SAX Exception Warning: can't output text before document element! Ignoring..."

What am I doing wrong? Would I need to serilalize the output to display the result Node as html?

This is the code I have been able to write:

import org.apache.xalan.xslt.XSLTEngineImpl;
import org.apache.xalan.xslt.XSLTProcessor;
import org.apache.xalan.xslt.XSLTInputSource;
import org.apache.xalan.xslt.XSLTResultTarget;
import org.apache.xalan.xslt.XSLTProcessorFactory;
import org.apache.xalan.xpath.xml.JaxpLiaison;
import org.apache.xalan.xpath.xdom.*;
import org.apache.xalan.xpath.xml.XMLParserLiaisonDefault;
import org.apache.xalan.xpath.xml.JaxpLiaison;
import org.apache.xml.serialize.*;
import com.sun.xml.*;
import com.sun.xml.tree.XmlDocument;

public class DisplayItemsBean extends Object {

public XmlDocument createDocument(String xml){

XmlDocument xmlDoc = new XmlDocument();

   try
    {
     ByteArrayInputStream in = new ByteArrayInputStream(xml.getBytes());
     xmlDoc = XmlDocument.createXmlDocument (in, false);

     }
    catch (SAXParseException e)
     {
    //Handle Exception
      }
     catch (SAXException e)
     {
    //Handle Exception
     }
     catch (java.io.IOException e)
     {
     //Handle Exception
      }

return xmlDoc;

}

public void process(XmlDocument inDoc) throws Exception {

XmlDocument doc = new XmlDocument();
Node outputNode = (Node)doc;

XSLTResultTarget rt = new XSLTResultTarget (outputNode);

    try{
       XSLTInputSource xsltIn = new XSLTInputSource();
       xsltIn.setSystemId("xsl address");

XSLTInputSource xmlIn = new XSLTInputSource(inDoc.getDocumentElement());

XSLTProcessor processor = XSLTProcessorFactory.getProcessor(new JaxpLiaison());

       processor.process(xmlIn,
       xsltIn,
       rt);

}

Node output = rt.getNode();

catch(Exception e){
System.out.println(e.getMessage());
}
}

Both the XML and XSL have been successfully processed before

my XML :

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<orderProviderList><startDate>15-Apr-2001</startDate><endDate>25-Apr-2001</endDate><order><order_no>10002</order_no>
<buyer_name>Heyster</buyer_name><order_date>16/04/2001 08:05</order_date><order_total>R0.00</order_total>
</order><order><order_no>10003</order_no><buyer_name>David</buyer_name><order_date>16/04/2001 19:58</order_date>
<order_total>R597.61</order_total></order><order>

my XSL:

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<output>
<xsl:template match="/">

<tr bgcolor="#e9e9df">

</tr>
<xsl:for-each select="orderProviderList/order">

     </xsl:attribute>
      <xsl:value-of select="order_no"/>
    </a>
</td>
<td align="left" valign="top" class="text">
   <xsl:value-of select="buyer_name"/>
</td>
<td align="left" valign="top" class="text">
   <xsl:value-of select="order_date"/>
</td>
<td align="right" valign="top" class="text">
   <xsl:value-of select="order_total"/>
</td>
</tr>
</xsl:for-each>
</xsl:template>
</output>
</xsl:stylesheet>
