Re: coding style... not sure if this kind of stuff is what you mean, but here's what I do... Generally no column restrictions, though I often prefer to keep the xsl:stylesheet start tag within 80 columns. It looks nice if you line up all the attributes one above the other. :) When I was using very large stylesheets that I didn't share with anybody, and a text editor with configurable tab widths, I greatly preferred tabs for indenting, to keep the file sizes down. When I was using a Makefile to manage the compilation of non-XSLT code in the same project, I had it also produce condensed versions of my stylesheets (identity transform + whitespace and comment removal.. see http://skew.org/xml/ under condense.xsl), resulting in relatively unreadable but slightly more efficient versions for the application to use. When writing stylesheets to share with the world, I use 2-space indents, which also look good in email. Literal result element names I try to keep to all lowercase or camelCase. Variable names I usually camelCase or hyphenate-like-this. I add frequent comments to explain why I'm doing whatever I'm doing. Use character references like " " ...don't waste your time with entities. General advice: I don't like the push/pull metaphors, but in general, I try to push as much as possible (using apply-templates and many match templates, rather than for-each and long XPaths in one big template). xsl:import and template modes can be *very* useful. Learn when. The XPath and XSLT specs are your friends as well. Perhaps they are a bit thick with technical terminology and poorly organized at first (I mean, what's with explaining the XPath data model at the very end?), but they are invaluable references once you get over the hump. - Mike ____________________________________________________________________________ mike j. brown | xml/xslt: http://skew.org/xml/ denver/boulder, colorado, usa | resume: http://skew.org/~mike/resume/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
