Thank you Michael. This is my first use of xsl:iterate and very useful in
understanding how it works. Here is my finished test stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:rq="http://www.frameexpert.com"
exclude-result-prefixes="xs rq"
version="3.0" expand-text="yes">
<xsl:output indent="yes"/>
<xsl:param name="line" select="'Acceptable HAZMAT Items - Carry-On Or
Checked Bags - Passenger and Cargo Flights'"/>
<xsl:template name="xsl:initial-template">
<xsl:message select="''"/>
<line>
<xsl:call-template name="line">
<xsl:with-param name="input" select="$line"/>
<xsl:with-param name="break-count" select="34"
as="xs:integer"/>
</xsl:call-template>
</line>
</xsl:template>
<xsl:template name="line">
<xsl:param name="input"/>
<xsl:param name="break-count" as="xs:integer"/>
<xsl:iterate select="tokenize($input)">
<xsl:param name="line-length" select="0"/>
<xsl:param name="break-count" select="$break-count"/>
<xsl:message select="position()=last()"></xsl:message>
<xsl:choose>
<xsl:when test="$line-length gt $break-count">
<break/>
<xsl:value-of select="concat(.,if(position()!=last())
then ' ' else '')"/>
<xsl:next-iteration>
<xsl:with-param name="line-length"
select="string-length(.) + 1"/>
<xsl:with-param name="break-count"
select="$break-count - 5"/>
</xsl:next-iteration>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="concat(.,if(position()!=last())
then ' ' else '')"/>
<xsl:next-iteration>
<xsl:with-param name="line-length"
select="$line-length + string-length(.) + 1"/>
<xsl:with-param name="break-count"
select="$break-count"/>
</xsl:next-iteration>
</xsl:otherwise>
</xsl:choose>
</xsl:iterate>
</xsl:template>
</xsl:stylesheet>
which gives me this:
<?xml version="1.0" encoding="UTF-8"?>
<line>Acceptable HAZMAT Items - Carry-On <break/>Or Checked Bags - Passenger
and <break/>Cargo Flights</line>
Thanks again!
