Technically, it is not complex. Just define a function my:codepoints-to-string() that makes the needed checks and do what you want when encoutering an invalid codepoint. I think the most difficult part is identifying which codepoints are valid. You can use the following from the XML recommendation as starting point: Florent: wow! Just wow ;) Thanks for the extensive explanation and the detailed xsl code. With all the possibilities to treat a non-number or div-by-zero without exceptions, I'm a little at odds as to why working with characters (which is at the basis of any xslt transform) is not made so rock-solid. Why didn't they invent something like <xsl:number> for characters? Funny, I never knew when/where to use the xsl:sequence constructor, I'm glad to have found a use through your code. Your code has been implemented into my filters. Thanks again! Cheers, -- Abel
