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

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???

Hi,

can please anyone indicate me,

First,

why i get the tag <br> in the output

if i have in the xml source

<memotext></memotext>

and my xsl-snippet is:

<xsl:value-of select="substring(../memotext, 1, 126)" />
<xsl:if test="string-length((../memotext) &gt; 126)"> <br /></xsl:if>
<xsl:value-of select="substring(../memotext, 127,
string-length(../memotext))"/>

What i am trying to do is counting the characters of the text-node of
memotext

and if the string-length is greater than 126 i want a <br />
only then.

Now i get always a <br />

Is the string-length counting from the position i call
<xsl:if test="string-length((../memotext) &gt; 126)"> <br /></xsl:if> ?

My XML- snippet:
etc ..
<row>
etc..
<memotext></memotext>

<DARKONTRAKT>
etc ..
<!-- from this level i match to test the value of memotext -->

</DARKONTRAKT>
</row>
etc ..

Second, how can i omit (not counting) the white-space characters by the
string-length calculation?

Third, how can i put the <br /> (linebreak) after 126 characters in the
output, when a white-space character occurs ?

Thanks,


Hans Braumüller
