Hi Ralf, Here is some code that I use to set indentation. Note that I am no Xalan guru; this works for me but may not be the "correct" solution.
OutputProperties outputFormat = new OutputProperties(); outputFormat.setProperty(OutputKeys.METHOD, Method.XML); outputFormat.setProperty(OutputKeys.INDENT, "yes"); outputFormat.setProperty(OutputProperties.S_KEY_INDENT_AMOUNT, "7"); Serializer serialiser = SerializerFactory.getSerializer(outputFormat.getProperties()); Note that if the original document has whitespace nodes, then the indenting won't occur (ie whitespace in the document overrides indenting). Try putting <xsl:strip-space elements="*"/> at the top-level of your stylesheet to see if that has the desired effect with your current code... Note also that setProperty with key of METHOD implicitly calls getDefaultMethodProperties, so this code isn't as different from yours as it appears. Which is the "right" approach I am not sure :-) Hope this helps, Simon > -----Original Message----- > From: Ralf Steppacher [mailto:[EMAIL PROTECTED] > Sent: Tuesday, July 09, 2002 7:57 PM > To: [EMAIL PROTECTED] > Subject: Serializer does not indent > > > Hello everybody. > > I tried to use the the org.apache.xalan.serialize Packge to > serialize a > DOM to System.out.
