Brian Minchau updated XALANJ-1446:
----------------------------------
Version: Latest Development Code
(was: 2.3)
> Transformations using DOMSource apply templates differently than with
> StreamSource
> ----------------------------------------------------------------------------------
>
> Key: XALANJ-1446
> URL: http://issues.apache.org/jira/browse/XALANJ-1446
> Project: XalanJ2
> Type: Bug
> Components: DTM
> Versions: Latest Development Code
> Environment: Operating System: All
> Platform: All
> Reporter: Joseph Sinclair
> Assignee: Xalan Developers Mailing List
>
> When transforming documents, the Xalan processor may produce different
> results
> when using the DOMSource vs. StreamSource. It applies the default templates
> to
> non-selected elements in the DOMSource document, but properly ignores non-
> selected elements (per XSLT) with the StreamSource. Note this generally
> shows
> up only when embedding Xalan into another application, as the command-line
> code
> uses the StreamSource to load the document to be transformed. This does not
> seem to be an issue if the DOMSource is used to load the stylesheet, only
> when
> the DOMSource is used to load the document to be transformed.
> As an example, execute the following code:
> _______________________________________________________________________________
> private static final String testDocumentString =
> "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" + System.getProperty
> ("line.separator", "\n") +
>
> "<!--********************************************************************-->"
> + System.getProperty("line.separator", "\n") +
> "<testRoot>" + System.getProperty("line.separator", "\n") +
> " <testHeader>" + System.getProperty("line.separator", "\n") +
> " <testItem>" + System.getProperty("line.separator", "\n") +
> " This is the testItem content" + System.getProperty
> ("line.separator", "\n") +
> " </testItem>" + System.getProperty("line.separator", "\n") +
> " </testHeader>" + System.getProperty("line.separator", "\n") +
> " <testPayload>" + System.getProperty("line.separator", "\n") +
> " <testValue item1=\"This is Item 1\" item2=\"This is Item 2\">" +
> System.getProperty("line.separator", "\n") +

> Note how the DOMSource run executes the default templates for the unmatched
> items prior to, and following, the one matched item. This despite the fact
> that the root template is overridden, and only the one item of interest is
> selected in the contained apply-templates rule. The StreamSource run
> correctly
> applies the defined template only to the selected item, and does not produce
> inappropriate output.
> This test was run with Xalan 2.3.1. I tried using both Xerces 1.4.4, and
> Xerces 2.3.0 for the XML parser used to build the DOM. In both cases the
> output was the same.
