Subject: Moving from LotusXSL to XT From: "Philip Puccio" <Philip.Puccio@xxxxxxxx> Date: 15 Dec 1999 15:36:36 -0700 |
Hi, I've got a production application implemented using LotusXSL and I'm investigating using XT instead. I've gotten some *very* simple transformations to work using XT, but there are 3 "techniques" I use in my production XSL that I'm having trouble mapping from LotusXSL to XT. I'm hoping some of you can help me clear these hurdles. Thanks! Here they are: 1) I frequently use xsl:include. With LotusXSL, to set up my stylesheet, I instantiate an XSLTInputSource, send it setCharacterStream(StringReader), where StringReader's string is my xsl, then I send the XSLTInputSource setSystemId(directoryName), where directoryName is where my XSL includes are located. That's been working fine for me. With XT, I do the same 2 message sends, but this time I use a org.xml.sax.InputSource instead of com.lotus.xsl.XSLTInputSource. When I use XT to process xsl that has an xsl:include, I get a MalformedURLException: no protocol: common-business-graph-call.xsl where the common... is the xsl file I was trying to include. How should I tell XT where it should look for include files? 2) I use extension functions to call some of my Java code. In one case, I pass a node-set as an argument to a Java method. Within Java (when using XT), that node-set is an instance of SingleNodeIterator. I send the iterator next() to get a Node (actually, an instance of XSLProcessorImpl$ElementNodeImpl). Now the challenge: I need to get a string representation of that Node's XML, tags and all. Using LotusXSL, I was getting an org.w3c.dom.NodeList, getting its only Node (an ElementImpl), casting it to a TXElement, then sending the TXElement the message toXMLString(Writer), implemented by com.ibm.xml.parser.Child. I can't find an analogous approach for a ElementNodeImpl. Is there an approach I'm missing? 3) In LotusXSL I was able to get nicely formatted output using indent="yes" on my xsl:output statement, combined with (in Java) sending setIndent(4) to an XMLParserLiaison that's associated with an instance of XSLProcessor. With XT, if indent="no", all output occurs on a single line; if indent="yes", each element occurs on its own line, but nothing is indented. How is indentation achieved using XT? Thanks for any light you can shed my way! . . . Phil Puccio XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
