Subject: [xsl] Escaped characters being duplicated From: "Anderson, Paul" <Paul.Anderson@xxxxxxxxxxxxx> Date: Tue, 11 Dec 2007 18:06:40 -0500 |
Greetings All, We have a bunch of DITA XML content and we're using the open-source DITA Open Toolkit to transform it into a variety of outputs. The DITA Open Toolkit is a collection of Java classes, XSL stylesheets, and ANT scripts that transform the content and create the output. To shield our users from the command-line invocation of the publishing scripts, we deployed a simple web application running on Tomcat 5.5 that takes input from a JSP page and invokes the necessary ANT script to generate the desired output for the user. This methodology has been working quite nicely for nearly a year. Over that time, a few of our users are having a problem where characters escaped in the XML content (for example, angle brackets and ampersands) are duplicated in the output. For example, in the place of one angle-bracket (<), we end up with two or sometimes four escaped angle brackets (<<<<). I've been troubleshooting the problem and the duplication always appears in the output files generated by one of the XSL stylesheets in the DITA Open Toolkit. If the input file contained an escaped character, the output file contains two of those escaped characters. The most interesting discovery so far is this: For each user that has the problem, the problem goes away if they invoke the ANT script via the command line; the duplication only occurs when the ANT script is invoked from the JSP page running on Tomcat 5.5. Having said that, the problem only exists for a few users; most users never see this problem when they use the JSP page to invoke the ANT script and publish the exact same XML content. Perplexing. Given all this background, my plea to this list is simple: What sort of conditions cause an XSL transformation to duplicate an escaped character? Would the system locale have an impact? Would the Java version (1.5 versus 1.6) have an impact? All source files use UTF-8 encoding. All users are using the same XSL processor: Saxon 6.5.5. I don't think the problem is in the XSL stylesheet or any other part of the DITA Open Toolkit because all users are using the same code and it works for most users. Any ideas about his issue are appreciated.
