Well, you're asking on the Xalan-J list, so I assume you're wanting an answer relevant to Xalan-J. Xalan is an XSLT processor, which means it follows rules defined in a stylesheet in order to create a new document based on an existing one. It doesn't modify the original document. You can use standard JAXP interfaces (javax.xml.*) to invoke Xalan-J with a DOMSource wrapping your original Document object and (assuming you want a DOM), a DOMResult to provide the product of the XSLT transformation as another Document object. I trust you can read the documentation on how to do that. A typical XSLT design pattern for making small changes to a document is to use a stylesheet containing a template that directs the processor to perform the "identity transformation": a recursive copy-through of the nodes in the source document. You supplement this template with other templates to override the handling of certain nodes. In this way, you can 'modify' the document. <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="no"/> <!--default for any node: recursively copy it--> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <!--override for 'foo' elements: rename them 'bar'--> <xsl:template match="foo"> <bar> <xsl:apply-templates select="@*|node()"/> </bar> </xsl:template> <!--override for 'baz' elements: eliminate them and their contents completely--> <xsl:template match="baz"/> </xsl:stylesheet> For general questions about XSLT, use xsl-list, about which there is info at http://www.mulberrytech.com/xsl/xsl-list/ There are other approaches to updating an XML document besides using XSLT. You could use DOM interfaces directly, you could use an XUpdate processor (though in either case, if you're going to go to that much trouble, you'll find XSLT easier and more robust), or you could reparse and manipulate the document using some other library that provides a DOM-like but easier/more efficient programmatic API. I believe there are quite a few of these available for various programming languages. Mike
