Multiple executions of transformation having DOM Document as parameter is not
working
-------------------------------------------------------------------------------------
Key: XALANJ-2067
URL: http://issues.apache.org/jira/browse/XALANJ-2067
Project: XalanJ2
Type: Bug
Components: Xalan
Versions: 2.6
Environment: Windows XP - jdk 1.4.1
Reporter: Alain Grandjean
Create a Transformer, set a DOM Document as parameter to the Transformer and
apply 2 times the Transformer. The second time, the parameter is no longer
containing the DOM Document.
Sample class Test.java:
package testxalan;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.StringReader;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.Source;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public class Test {
static Transformer newTransormer(String name) throws Exception
{
TransformerFactory factory = TransformerFactory.newInstance();
return factory.newTransformer(new StreamSource(new FileInputStream(name)));
}
static Document newDocument() throws Exception
{
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
factory.setValidating(false);
Document doc = factory.newDocumentBuilder().newDocument();
return doc;
}
public static void main(String[] args) {
try {
Transformer transformer = newTransormer("hello.xsl");
Document doc = newDocument();
Element root = doc.createElement("root");
root.appendChild(doc.createTextNode("Hello World"));
doc.appendChild(root);
transformer.setParameter("data", doc);
transformer.transform(new StreamSource(new StringReader("<node/>")), new
StreamResult(new FileOutputStream("sample1.txt")));
transformer.transform(new StreamSource(new StringReader("<node/>")), new
StreamResult(new FileOutputStream("sample2.txt")));
} catch (Exception e) {
e.printStackTrace();
}
}
}
with Sample hello.xsl:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:param name="data" select="/.."/>
<xsl:template match="node">
<xsl:value-of select="$data/root"/>
</xsl:template>
</xsl:stylesheet>
