[jdom-interest] JDOM, problems when transforming to HTML using XSL

[Lukas Hazlehurst]

Hi,

i'm using something similiar to the following code which outputs directly to
an output stream, without going thru the XMLOutputter. The "rs" variable is
a ResultSet which contains the XLST code, "data" is a Document which is the
xml to do the xslt transform against, "out" is the output stream.

Transformer transformer;
TransformerFactory tFactory = TransformerFactory.newInstance();
Templates t = tFactory.newTemplates(new StreamSource( new
ByteArrayInputStream( rs.getBytes("data") )));
transformer = t.newTransformer();
transformer.transform( new JDOMSource(data) , new StreamResult( out ));

In this case the xslt template has the <xsl:output method="html"
indent="yes" encoding="iso-8859-1"/> element.

This seems to work well form what i'm doing, producing the appropriate HTML
tags and so forth. Also, i can cache the transformer so subsequent
transforms are a bit quicker.
