This is best done with a recursive named template to which you pass the string and that outputs it 60 characters at a time. The relevant function is substring(), which enables you to get a substring n characters long. So, first I'm going to declare a parameter that will hold the number of characters you want per line, just in case you want to vary that later on, or for different runs of the same stylesheet: <xsl:param name="break-at" select="'60'" /> Then the recursive template. You're going to pass it the parameter that is the string that you want to break up. If that string is under 60 characters long, then you just output that, otherwise you need to output the first 60 characters, then a break ('br' element - you can put an actual line break in instead if you want), and then call the template on the rest of the string: <xsl:template nmae="break-string"> <xsl:param name="string" /> <xsl:choose> <xsl:when test="string-length($string) <= $break-at"> <xsl:value-of select="$string" /> </xsl:when> <xsl:otherwise> <xsl:value-of select="substring($string, 1, $break-at)" /><br /> <xsl:call-template name="break-string"> <xsl:with-param name="string" select="substring($string, $break-at + 1)" /> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:template> Finally, you need to call this recursive template from somewhere, passing it the original string. Let's say that the string is the content of a 'p' element, then you need something like: <xsl:template match="p"> <xsl:call-template name="break-string"> <xsl:with-param name="string" select="." /> </xsl:call-template> </xsl:template> Note that this doesn't take account of the position of spaces in your string at all, although it would probably be possible to make it do so in some rudimentary way.
