Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Attila Szegedi (szegedia) Assigned to: Nobody/Anonymous (nobody) Summary: Comment before document element break transform Initial Comment: I have a trivial document (saved as "id.xml"): <!-- --><x/> And a trivial XSLT file (saved as "ad.xslt") that's just an identity transform: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version='1.0'> <xsl:template match='@*|*|processing-instruction()|comment()' priority='-2'> <xsl:copy> <xsl:apply-templates select='*|@*|text()|processing-instruction()|comment()'/> </xsl:copy> </xsl:template> </xsl:stylesheet> The following code, using no dom4j but just built-in javax.xml.parsers.* works, and prints a non-null element: import java.io.File; import java.net.URL; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.transform.Source; import javax.xml.transform.TransformerFactory; import javax.xml.transform.dom.DOMResult; import javax.xml.transform.dom.DOMSource; import javax.xml.transform.stream.StreamSource; import org.w3c.dom.Document; public class XsltTest { public static void main(String[] args) throws Exception { final Source docSource = new DOMSource(DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new File("id.xml"))); final DOMResult result = new DOMResult(); TransformerFactory.newInstance().newTransformer(new StreamSource( new File("ad.xslt"))).transform(docSource, result); final Document doc = (Document)result.getNode(); System.out.println(doc.getDocumentElement()); } } It prints "[x: null]", as expected. Now, replacing the "final Source docSource" declaration with a dom4j Document (using DOMDocumentFactory): final SAXReader reader = new SAXReader(); reader.setDocumentFactory(new DOMDocumentFactory()); final Source docSource = new DOMSource((Document)reader.read(new File("id.xml"))); will cause the program to print "null" - the transformed document now has no root element! Removing the comment from before <x/> fixes the problem, so it's the comment that makes it fail. This is with 1.6.1 ---------------------------------------------------------------------- >Comment By: Attila Szegedi (szegedia) Date: 2009-06-24 09:18 Message: For now, worked around it with a private build of dom4j. NOTE: I didn't find and fix the bug, I worked around it. What I did is I took the SAXReader.read(InputSource) method and doctored it so that it removes any top-level comments from the document before returning it. Would still prefer a proper fix. ---------------------------------------------------------------------- Comment By: Attila Szegedi (szegedia) Date: 2009-06-23 13:22 Message: It's possibly related to <https://sourceforge.net/tracker/?func=detail&aid=2432779&group_id=16035&atid=116035> ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=116035&aid=2810839&group_id=16035 ------------------------------------------------------------------------------ _______________________________________________ dom4j-dev mailing list dom4j-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dom4j-dev
