xsl count

<xsl:if test="$linecnt > $maxLine">
<xsl:call-template name="format">
<xsl:with-param select="substring($txt,$real-width + 1)" name="txt"/>

Balaji, is it a question or an answer?

Hi,
Sorry! I forgot to check again what i exactly pasted from my textpad after typing.
whats going on with me.
This is my question.
I want to split 'n' number of characters into 35 characters per line AND with a maximum of 5 lines and strip off rest of the characters.
I'm doing this for xsl:fo.
As usual (after i got failed) i copied the code from http://www.dpawson.co.uk/xsl/sect2/N7240.html#d60e246
But to stripoff characters more than 5 lines,i have to count the number of lines it has printed already.
so that i can code something like this in the above code after <xsl:text></xsl:text> line.
<xsl:if test="$lineCnt & l t; $maxLine">
<xsl:call-template name="format">
<xsl:with-param select="substring($txt,$real-width + 1)" name="txt"/>
<xsl:with-param select="$width" name="width"/>
</xsl:call-template>
where maxLine is 5 and the lineCnt will increase after printing each line.
But I couldn't able to do it as xsl doesn't support changing value.
I'm missing the logic here,i think i have to do something with recursive funtion.
Please help!!
Thanks

You can call the function 'position()' from e.g. 'xsl:if' and then validate what value it has.

I tried it,but its printing 0 in all occurences,I tried to place it in all possible place i can.
Basically what i tryin is
Input:
My little fox brown is blah blah end.
Output:
My lit
tle fo
x brow
n is b
lah bl
Condition is "max n lines(say 6),max 6 characters per line,strip of rest.
This I'm doing this for XSL:fo because in xsl:fo if i allow more than 5 lines in a table,its renders to second page, which it shoud not.

i guess u have to do some recursion here.

  
<!-- just decalred some global variables here -->
    <xsl:variable name="maxLen" select="10"/>
    <xsl:variable name="maxLines" select="5"/>
    <xsl:varible name="line" select="'string that you want to process'"/>
    <xsl:variable name="newLine">
        <xsl:text>
        </xsl:text>
    </xsl:variable>    
    <xsl:template match="/">
        <xsl:call-template name="print">
            <xsl:with-param name="content" select="$line"/>            
        </xsl:call-template>
    </xsl:template>
    
    <xsl:template name="print"> 
        <xsl :-P	 aram name="content"/>
        <xsl :-P	 aram name="counter" select="1"/>
        <xsl:variable name="result">
            <xsl:value-of select="substring($content,0,$maxLen+1)"/>
        </xsl:variable>                
        <xsl:variable name="rest">
            <xsl:value-of select="substring($content,$maxLen)"/>
        </xsl:variable>                
        <xsl:value-of select="$newLine"/>
        <xsl:value-of select="$result"/>
        <xsl:if test="$counter < $maxLines">
            <xsl:call-template name="print">
                <xsl:with-param name="content" select="$rest"/>
                <xsl:with-param name="counter" select="$counter + 1"/>
            </xsl:call-template>
        </xsl:if>            
    </xsl:template>

am not sure if i got your question right though.
anyways HTH

Hi Karthik,
This is what i'm trying for,felt bad that I couldn't able to code this of my own.Thanks a lot.
I just changed the rest variable code to avoid re-occurences of last line character.

<xsl:variable name="rest">
<xsl:value-of select="substring($content,$maxLen + 1)"/>
</xsl:variable>

Thanks again
