Guy,
Part 1 of your question really has nothing to do with Xalan, per se. You're asking how to validate an XML instance document, as a DOM tree, against its schema. This depends entirely on your DOM implementation. But, assuming you're using JAXP and Xerces, without using Xerces-specific classes there aren't very many really graceful or efficient ways to do it. One way that I've done it is to serialize the DOM document into a stream buffer, then read/parse/validate the stream buffer into another DOM tree in the same way you might process an instance document from a disk file or another URL.
If you want to validate using the Xerces-specific classes, you might post this question to the Xerces-J list. I think that might also be a more appropriate place to get an answer to part 2 of your question.

Hi,
(Two part question)
How do I make sure the DOM tree held by the DOMResult object after transformation complies to an XML Schema? (e.g. to the eg.xsd schema below)
I have the following in xsl <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0" xmlns:xalan="http://xml.apache.org/xslt"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; exclude-result-prefixes="xmlns">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="no"/> <root xmlns="http://example"; xmlns:eg="http://example"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://example file:eg.xsd"> ... </root> ... </xsl:transform>
Second part:
How do I use a grammar pool (preparsed schema) to have the DOMResult comply to.
Thanks, Guy
