Hello, I've a journal, which stores its data in an XML file. I use XSLT to dynamically transform this into various output formats - XHTML in this case, based on various criteria such as the date to display and so on. The XSLT used to do this transformation is available here http://nedmartin.org/journal/xsl/ , although it is probably not very relevant to my question. 'day.xsl' shows single days; 'full.xsl' shows full years and so forth. 'journal-imports.xsl' does the actual transformation. I also have an XML list of acronyms used throughout my journal, formatted thus: Cascading Style Sheet Common Gateway Interface (web scripting facility) or Computer-Generated Imagery (movie industry) ... I wish to be able to automatically replace any occurrence of an acronym in the XHTML output with the appropriate XHTML CSS tag. I have thought about it and I can't think of any way to do this that wouldn't involve parsing my journal and on every single word of my journal, parsing every single acronym in my acronyms list - thus for every word in my journal my entire acronym list would be parsed - something I assume would be highly inefficient. In case it matters, my journal is in the format: blah blah ... ... ... or view the schema: http://nedmartin.org/journal/xsl/journal.xsd There has to be a good way to do this? Help much appreciated, Ned Printed on 100% recycled electrons. http://nedmartin.org XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
