Re: [xsl] count string-length without white-space and breaking if white-spa ceexists after 126 characters

["Vasu Chakkera" <vasucv at hotmail dot com>]

Hans ,
The following is your solution
I have considered the following XML..

<row>
<memotext>abcdefghijklmm....</memotext>
<!-- assumption that you have more of the darkonrakt elements and u want to 
check the memotext text length at every <darkonrakt> node..
-->
<darkonrakt>
</darkontract>
<darkonrakt>
</darkontract>
<darkonrakt>
</darkontract>
</row>

( just added the parent element.. )

the xsl to get the Break if the string length exceeds 126 characters would 
be:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:for-each select="/row/darkonrakt">
<xsl:choose>
<xsl:when test="string-length(preceding::memotext)&gt;126">
<!-- or <xsl:when test="string-length(../memotext)&gt;126"> -->
<xsl:value-of select="string-length(preceding::memotext)"/>
<br></br>
</xsl:when>
<xsl:otherwise>
no break becoz the length of the memo text is <xsl:value-of 
select="string-length(preceding::memotext)"/> which is less than 126
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
This code will output a <br></br> and the string length(just for 
verification )if the string-length of the memotext is greater that 126 ... 
if it is less , then it outputs a string "no break because the"+ 
string-length +" is lesser than 126".

Will this serve your purpose???
