Re: [xsl] Text output line width setting technique

[Senthilukvelaan <skumaravelan@xxxxxxxxxxxxxx>]

Hi All,
I have found a solution for the same.
<xsl:template name="wrap-string">
    <xsl:param name="str" />
    <xsl:param name="wrap-col" />
    <xsl:param name="break-mark" />
    <xsl:param name="pos" select="0" />
    <xsl:choose>
        <xsl:when test="contains( $str, ' ' )">
            <xsl:variable name="before" select="substring-before(
$str, ' ' )" />
            <xsl:variable name="pos-now" select="$pos + string-length(
$before )" />

            <xsl:choose>
                <xsl:when test="$pos = 0" />
                <xsl:when test="floor( $pos div $wrap-col ) != floor(
$pos-now div $wrap-col )">
                    <xsl:copy-of select="$break-mark" />
                </xsl:when>
                <xsl:otherwise>
                    <xsl:text> </xsl:text>
                </xsl:otherwise>
            </xsl:choose>

            <xsl:value-of select="$before" />

            <xsl:call-template name="wrap-string">
                <xsl:with-param name="str" select="substring-after(
$str, ' ' )" />
                <xsl:with-param name="wrap-col" select="$wrap-col" />
                <xsl:with-param name="break-mark" select="$break-mark" />
                <xsl:with-param name="pos" select="$pos-now" />
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:if test="$pos &gt; 0"><xsl:text> </xsl:text></xsl:if>
            <xsl:value-of select="$str" />
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>
and it can be invoked by calling
     <xsl:call-template name="wrap-string">
        <xsl:with-param name="str" select="normalize-space(.)"/>
        <xsl:with-param name="wrap-col" select="80"/>
        <xsl:with-param name="break-mark" select="'&#9;&#10;&#13;'"/>
      </xsl:call-template>
I hope it might help one like me.
