Subject: [xsl] Split string into multiple sentences on word boundaries From: "Bordeman, Chris" <Chris.Bordeman@xxxxxxxxxxxxxxxxx> Date: Thu, 9 Apr 2009 14:04:43 -0500 |
Hi all. I have a long string, need to break it up onto say 3 lines (may vary), with a maximum of 10 characters on the first line, 50 on the second, and 20 on the last line (all of which varies). I can't just split at any character, I need to split between words. Is there is a function already written somewhere that does something like this? Using Xslt 2.0 / Saxon. Many thanks!

Since I am using alot more heavy-duty XSL, I am now hitting barriers with performance. My quesiton to the forum is for once, not a beginner's question! In transforming the <syl> tags below into HTML table cells to display them, I need to format each cell with a green color with the running total of the @length attributes is a multiple of four. Ideally having the ability to do running totals in another variable would be great, but not the best XSL-esque solution, so I am using axes instead. I have tried solutions with count and sum, but performance is slow: 756 lines like the ones below mean thousands of syllables to check, each with its own axis computation -- the complete xform takes more than an hour! Can anyone point me to a solution that is more performant yet still elegant/simple? An aside: it seems that ceiling() is an Xpath1.0 function, but oddly enough not floor() -- Altova SPY complains about floor until I change the stylesheet to version 2.0 (sigh). I would love this to transform in XSL1.0 if possible, and rounding down each length to the integer is essential to acheive the correct formatting result. Thanks in advance for any help on this.
