Richard Opalka commented on XALANJ-2382:
----------------------------------------
To workaround your problem with SAXSource
you need to configure SAX stream parser with the following feature
http://xerces.apache.org/xerces2-j/features.html#namespace-prefixes
and associate this reader with SAXSource
For example:
private static final class SAXSourceProvider extends
SourceProvider<SAXSource> {
protected SAXSourceProvider(String xml) { super(xml); }
@Override
public SAXSource newSource() throws Exception {
SAXParserFactory saxFactory = SAXParserFactory.newInstance();
saxFactory.setNamespaceAware(true);
XMLReader reader = saxFactory.newSAXParser().getXMLReader();
reader.setFeature("http://xml.org/sax/features/namespaces";, true);
reader.setFeature("http://xml.org/sax/features/namespace-prefixes";,
true); // important - it's false by default
SAXSource retVal = new SAXSource(new InputSource(new
StringReader(xml)));
retVal.setXMLReader(reader);
return retVal;
}
}
> Namespace declarations are lost on transformation to DOMResult

> Key: XALANJ-2382
> URL: https://issues.apache.org/jira/browse/XALANJ-2382
> Project: XalanJ2
> Issue Type: Bug
> Components: DOM, JAXP, Xalan
> Affects Versions: 2.7.1, 2.7
> Environment: Intel Pentium 4
> Windows 2000 SP4
> Sun JDK 6 (build 1.6.0-b105)
> Reporter: Christian Koppen
> Attachments: output.txt, TransformerTest.java
>
>
> Have a look at the following snippet:
> <a:a1 xmlns:a="http://a";
> xmlns:b="http://b";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
> <a:a2 xsi:type="b:B"/>
> </a:a1>
> As you can see, the value of the attribute 'xsi:type' contains a namespace
> prefix, which is declared in the root element.
> When I read this document as a StreamSource or SAXSource and transform it
> with Xalan into a DOMResult, the namespaces are invalid because the namespace
> declaration 'xmlns:b="http://b";' is lost:
> <a:a1 xmlns:a="http://a";>
> <a:a2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xsi:type="b:B"/>
> </a:a1>
> When I try to read the document as a DOMSource and try to transform it into a
> DOMResult, an exception occurs ('NAMESPACE_ERR: An attempt is made to create
> or change an object in a way which is incorrect with regard to namespaces.').
> I attach the example code and output.
