Wrap within table-cell with long word in FOP

Question

I have a table in FOP and it is working nicely until I get a very long word. The word then overwrites the cell ending in the table. I tried the wrap-option="wrap" within the table-cell and/or the block of the cell but it doesn't work

**Total Edit**

since I guess it is to complicated to just show bits here is the complete xsl file:

The cell data4 is the one with the problems.... like 255 digits or characters at once with no hyphen oder space.

The input is from a database but could be like:

 <datasheet>
   <dataList>
     <data1>intro</data1>
     <data2>section</data2>
     <data3>cutters</data3>
     <data4>743576746876357467569384657654687465874638563465873487435767468763574675693846576546874658746385634658734874357674687635746756938465765468746587463856346587348743576746876357467569384657654687465874638563465873487435767468763574675693846576546874658746385634658734874357674687635746756938465765468746587463856346587348743576746876357467569384657654687465874638563465873487435767468763574675693846576546874658746385634658734874357674687635746756938465765468746587463856346587348743576746876357467569384657654687465874638563465873487435767468763574675693846576546874658746385634658734874357674687635746756938465765468746587463856346587348</data4>

   </dataList>
 </datasheet>

the result should be a table like:

|cell1  |cell2  |cell3  |cell4  |
_________________________________
|intro  |section|cutters|7435767|
                        |4687635|
                        |7467569|
                        |3846576|
_________________________________

and so on in cell 4

Now the above works

Answer 1

<xsl:template name="intersperse-with-zero-spaces">
<xsl:param name="str"/>
<xsl:variable name="spacechars">
    &#x9;&#xA;
    &#x2000;&#x2001;&#x2002;&#x2003;&#x2004;&#x2005;
    &#x2006;&#x2007;&#x2008;&#x2009;&#x200A;&#x200B;
</xsl:variable>

<xsl:if test="string-length($str) &gt; 0">
    <xsl:variable name="c1" select="substring($str, 1, 1)"/>
    <xsl:variable name="c2" select="substring($str, 2, 1)"/>

    <xsl:value-of select="$c1"/>
    <xsl:if test="$c2 != '' and
        not(contains($spacechars, $c1) or
        contains($spacechars, $c2))">
        <xsl:text>&#x200B;</xsl:text>
    </xsl:if>

    <xsl:call-template name="intersperse-with-zero-spaces">
        <xsl:with-param name="str" select="substring($str, 2)"/>
    </xsl:call-template>
</xsl:if>
</xsl:template> 

calling place use to call like below:

<fo:block text-align="left">
   <xsl:call-template name="intersperse-with-zero-spaces">
<xsl:with-param name="str" select="data4"/>
</xsl:call-template>
  </fo:block>

I tested, it's working fine.

Answer 2

One option would be for you to break up the long number/word in XSLT while you're transforming to FO. You'd have to decide where you want it to break.

See also: XSL-FO fop. Long text flows into adjacent cells/block, obscuring stuff there

Update (copied from comment):

There must be copy/paste errors in the stylesheet... there is an <xsl:param>, which is only supposed to occur at the beginning of a template, in the middle of the template. The stylesheet is therefore invalid. Are there supposed to be two templates? Also, I don't yet see the template named intersperse-with-zero-spaces; but maybe you're still adding it.

Update 2:

The above has been fixed in the Question.

I had assumed the second template couldn't be intersperse-with-zero-spaces, since it was calling that template. It didn't occur to me that it was supposed to be a recursive template!

By the way, if you have the option of using XSLT 2.0, the intersperse-with-zero-spaces template could be replaced by a much more efficient regexp replace.
