Hi Bernmeister, The one thing I see: the second parameter to evaluate, item, should not be a String but the root node of your document.

I believe I've managed to get to the point of getting a document back from the transformation. The code is below: FopFactory fopFactory = FopFactory.newInstance(); FOUserAgent foUserAgent = fopFactory.newFOUserAgent(); SAXTransformerFactory saxTransformerFactory = (SAXTransformerFactory)TransformerFactory.newInstance(); TransformerHandler transformerHandler = saxTransformerFactory.newTransformerHandler( new StreamSource( m_xslStylesheet ) ); DOMResult domResult = new DOMResult(); transformerHandler.setResult( domResult ); ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); BufferedOutputStream bufferedOutputStream = new BufferedOutputStream( new FileOutputStream( m_outputPDFFile ) ); Fop fop = fopFactory.newFop( MimeConstants.MIME_FOP_AREA_TREE, foUserAgent, bufferedOutputStream ); Transformer transformer = saxTransformerFactory.newTransformer(); // Set report parameters... Set<String> xslKeys = m_xslParams.keySet(); for( String xslKey : xslKeys ) transformer.setParameter( xslKey, m_xslParams.get( xslKey ) ); Source source = new StreamSource( m_xmlData ); Result result = new SAXResult( transformerHandler ); saxTransformerFactory.newTransformer().transform( source, result ); Document document = (org.w3c.dom.Document)domResult.getNode(); XPathFactory factory = XPathFactory.newInstance(); String expression = ".//blo...@id='" + "HeaderID" + "']/@bpd"; String item = "fo:block"; QName returnType = XPathConstants.NUMBER; Object returnValue = factory.newXPath().evaluate( expression, item, returnType ); double height_in_milipoints = Double.parseDouble( (String)returnValue ); The for loop is used to set report parameters such as page size, page margins, report title, etc. When I run the above code, I get an XPathExpressionException. Unfortunately there is no detailed message. The snippet of my XSL file is: <fo:static-content flow-name="xsl-region-before"> <fo:block id="HeaderID" font-family="{$header-font-family}" font-size="{$header-font-size}" font-style="{$header-font-style}" text-align="center"><xsl:value-of select="$report-title"/></fo:block> </fo:static-content> I'm not sure what I am doing wrong. When I debug the Java and inspect the "document" variable it seems to have lots of stuff - but can't actually figure out how to locate the node I want. If easier or you prefer, send me a direct email and we can then work out how to IM each other. Thanks again, Bernmeister. -- View this message in context: http://www.nabble.com/Change-the-header-footer-size-in-a-PDF-tp23209748p23248181.html Sent from the FOP - Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: fop-users-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: fop-users-h...@xmlgraphics.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: fop-users-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: fop-users-h...@xmlgraphics.apache.org
