[jira] Created: (XERCESJ-1147) Parsed document is not fully
initialized until getFirstChild() is called
Parsed document is not fully initialized until getFirstChild() is called
------------------------------------------------------------------------
Key: XERCESJ-1147
URL: http://issues.apache.org/jira/browse/XERCESJ-1147
Project: Xerces2-J
Type: Bug
Versions: 2.8.0
Environment: java version "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
Saxon: saxonb8-7j
Reporter: Libor Valenta
I have problems with Xerces bundled with JDK 1.5 as well as Xerces-J 2.8.0, I was usin XSLT 2.0 transformer Saxon 8.7 to access document produced by java extension. Problems go away when I call document.getFirstChild(); before returning document for the transformation, the side-effect of getFirstChild() makes me believe that there is something wrong with implementation of the Document.
Here is simple code to demostrate the problem Test .java:
import org.w3c.dom.Document;
import org.xml.sax.InputSource;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import java.io.StringReader;
import java.io.StringWriter;
public class Test {
// this will call test1() which DOES call getFirstChild() before document is returned
static String XSL1 = "<?xml version=\"1.0\"?>\n" +
"<xsl:stylesheet xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\" version=\"2.0\" xmlns:test=\"Test\">\n" +
" <xsl:template match=\"/\">\n" +
" <xsl:copy-of select=\"test:test1()\"/>\n" +
" </xsl:template>\n" +
"</xsl:stylesheet>";
// this will call test2() which DOES NOT call getFirstChild() before document is returned
static String XSL2 = "<?xml version=\"1.0\"?>\n" +
"<xsl:stylesheet xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\" version=\"2.0\" xmlns:test=\"Test\">\n" +
" <xsl:template match=\"/\">\n" +
" <xsl:copy-of select=\"test:test2()\"/>\n" +
" </xsl:template>\n" +
"</xsl:stylesheet>";
public static void main(String[] args) throws Exception {
transform(XSL1); // Result is: <?xml version="1.0" encoding="UTF-8"?><y/>
transform(XSL2); // Result is:
}
private static void transform(String xsl) throws TransformerException {
Transformer transformer = TransformerFactory.newInstance().newTransformer(new StreamSource(new StringReader(xsl)));
StringWriter out = new StringWriter();
transformer.transform(new StreamSource(new StringReader("<x/>")), new StreamResult(out));
System.out.println("Result is: " + out);
}
public static Document test1() throws Exception {
DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = documentBuilder.parse(new InputSource(new StringReader("<y/>")));
// next call has some side-effect that make things work, synchronizeChildren() ?
// likely bug in com.sun.org.apache.xerces.internal.dom.DeferredDocumentImpl
document.getFirstChild();
return document;
}
public static Document test2() throws Exception {
DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = documentBuilder.parse(new InputSource(new StringReader("<y/>")));
return document;
}
}
I do not know how Saxon is using the document, but whatever it does, it should behave same way for test1() and test2()

-----------------------------------------------
Your guess is as good as mine. The JDK development/maintenance operates independently of this project. If you're looking for a fix there you'll need to pursue it with Sun.

[jira] Resolved: (XERCESJ-1147) Parsed document is not fully
initialized until getFirstChild() is called
Posted by "Michael Glavassevich (JIRA)" <xe...@xml.apache.org>.
[ http://issues.apache.org/jira/browse/XERCESJ-1147?page=all ]
Michael Glavassevich resolved XERCESJ-1147.
-------------------------------------------
Fix Version/s: 2.8.1
Resolution: Fixed
Seems like Saxon is casting a Xerces' DOM node directly to a NodeList. Because this bypasses the synchronizeChildren() call in ParentNode.getChildNodes() the children may not be expanded yet if getLength() or item() are called on the NodeList. This should be fixed now.
