> Creating in-memory DocumentFragment with imbedded null text elements causes
> Trax NPE
> ------------------------------------------------------------------------------------
>
> Key: XALANJ-2265
> URL: http://issues.apache.org/jira/browse/XALANJ-2265
> Project: XalanJ2
> Type: Bug
> Components: XSLTC
> Versions: 2.7
> Environment: cygwin under XP, java 1.4.2_09
> Reporter: Travis Winfrey
> Assignee: Henry Zongaro
>
> The trax library cannot handle the null text element, when a DocumentFragment
> is created that has some null text nodes. In contrast, other XSLTC libraries
> treat the middleName=null variation shown below as <MiddleName/>
> Example code to create DocumentFragment with null text element
> import org.w3c.dom.Document;
> import org.w3c.dom.DocumentFragment;
> import org.w3c.dom.Element;
> public DocumentFragment createDocFragment(Document doc) throws
> ParserConfigurationException, NullPointerException {
> DocumentFragment docFrag = doc.createDocumentFragment();
> Element person = doc.createElement("Person");
> String firstName = "George";
> String middleName = "";
> String lastName = "Washington";
> if (this.isMiddleNameNull) {
> middleName = null;
> }
>
> person.appendChild(doc.createElement("FirstName")).appendChild(doc.createTextNode(firstName));
>
> person.appendChild(doc.createElement("MiddleName")).appendChild(doc.createTextNode(middleName));
>
> person.appendChild(doc.createElement("LastName")).appendChild(doc.createTextNode(lastName));
> docFrag.appendChild(person);
> return docFrag;
> }
> Sample xsl code to tickle bug. any of these will work .
> <xsl:value-of select="/Person/MiddleName" />
> <xsl:value-of select="." />
> <xsl:value-of select="./*" />
> One cause of the NPE is org.apache.xalan.xsltc.trax.DOM2SAX.parse routine
> looks like this:
> private void parse(Node node) throws IOException, SAXException {
> // .. tlw omit 5 lines ...
> switch (node.getNodeType()) {
> // ... tlw omit 131 lines ...
> case Node.TEXT_NODE:
> final String data = node.getNodeValue();
>
> _sax.characters(data.toCharArray(), 0, data.length()); // tlw:
> kaboom
> break;
> }
> }
