----------------------------------
This issue only appears when I try to sort a nodeset within an applet. Using
the same programming logic and stylesheets from within a console application
works as expected:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import org.w3c.dom.*;
import java.io.*;
import org.xml.sax.*;
import javax.xml.parsers.*;
public class ControlPanel {
public static void main(String[] args) {
String strDoc = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<root/> \n" ;
String strStyle =
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<stylesheet \n" +
" xmlns=\"http://www.w3.org/1999/XSL/Transform\"; \n" +
" xmlns:xalan=\"http://xml.apache.org/xalan\"; \n" +
" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\"; version=\"1.0\">\n" +
" <output method=\"text\"/>\n" +
"\n" +
" <template match=\"/\">\n" +
" <variable name=\"foo\">\n" +
" <xsl:element name=\"bar\">\n" +
" <xsl:attribute name=\"priority\">1</xsl:attribute>\n" +
" <text>Priority = 1</text>\n" +
" </xsl:element>\n" +
" <xsl:element name=\"bar\">\n" +
" <xsl:attribute name=\"priority\">2</xsl:attribute>\n" +
" <text>Priority = 2</text>\n" +
" </xsl:element>\n" +
" </variable>\n" +
" <for-each select=\"xalan:nodeset($foo)/xsl:bar\">\n" +
" <xsl:sort data-type=\"number\" order=\"descending\"
select=\"@priority\"/>\n" +
" <value-of select=\"text()\"/>\n" +
" </for-each>\n" +
" </template>\n" +
"</stylesheet>\n";
System.out.println(strDoc);
System.out.println(strStyle);
try {
DocumentBuilderFactory docBuilderFactory = (DocumentBuilderFactory) new
com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl();
docBuilderFactory.setIgnoringComments(false);
docBuilderFactory.setIgnoringElementContentWhitespace(false);
docBuilderFactory.setCoalescing(false);
docBuilderFactory.setExpandEntityReferences(true);
docBuilderFactory.setValidating(false);
docBuilderFactory.setNamespaceAware(true);
DocumentBuilder builder = docBuilderFactory.newDocumentBuilder();
StringReader sourceReader = new StringReader(strDoc);
StringReader styleReader = new StringReader(strStyle);
InputSource sourceInput = new InputSource(sourceReader);
InputSource styleInput = new InputSource(styleReader);
Document sourceDoc = builder.parse(sourceInput);
Document styleDoc = builder.parse(styleInput);
DOMSource sourceDOM = new DOMSource(sourceDoc);
DOMSource styleDOM = new DOMSource(styleDoc);
TransformerFactory transformerFactory = new
com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl();
Templates templates = transformerFactory.newTemplates(styleDOM);
Transformer transformer = (Transformer) templates.newTransformer();
StringWriter resultWriter = new StringWriter();
StreamResult resultStream = new StreamResult(resultWriter);
transformer.transform(sourceDOM, resultStream);
String tranResult = resultWriter.toString();
System.out.println(tranResult);
} catch (Exception e) {
System.out.println(e.toString());
}
}
}
Produces the following output:
Priority = 2Priority = 1
> xsl:sort does not work with nodeset variables

> Key: XALANJ-2180
> URL: http://issues.apache.org/jira/browse/XALANJ-2180
> Project: XalanJ2
> Type: Bug
> Components: Xalan
> Versions: 2.6
> Environment: Java Plug-in 1.5.0_04 creates DocumentBuilderFactory,
> TransformerFactory, Transformer objects etc. using newInstance() methods.
> Reporter: dcaveney
> Attachments: Scenario.zip, sortbug.xsl
>
> The symptoms I'm seeing are the same as in issue #Xalanj-860 but I can't use
> the same workaround. A template creates some elements within a variable, and
> then tries to sort the resulting nodeset. The following example produces no
> output:
> <?xml version="1.0" encoding="UTF-8"?>
> <stylesheet xmlns="http://www.w3.org/1999/XSL/Transform";
> xmlns:xalan="http://xml.apache.org/xalan";
> xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
> <output method="text"/>
> <template match="/">
> <variable name="foo">
> <xsl:element name="bar">
> <xsl:attribute name="priority">1</xsl:attribute>
> <text>Priority = 1</text>
> </xsl:element>
> <xsl:element name="bar">
> <xsl:attribute name="priority">2</xsl:attribute>
> <text>Priority = 2</text>
> </xsl:element>
> </variable>
> <for-each select="xalan:nodeset($foo)/xsl:bar">
> <xsl:sort data-type="number" order="descending" select="@priority"/>
> <value-of select="text()"/>
> </for-each>
> </template>
> </stylesheet>
