Wrap within table-cell with long word in FOP - xslt

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">
      
     ​
</xsl:variable>
<xsl:if test="string-length($str) > 0">
<xsl:variable name="c1" select="substring($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, $c2))">
<xsl:text>​</xsl:text>
</xsl:if>
<xsl:call-template name="intersperse-with-zero-spaces">
<xsl:with-param name="str" select="substring($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.

Answer 3

Add hyphenate="true", then it will automatically adjust the spaces in the table cell.
<fo:table-cell border-bottom-width="0px" border-left-width="0px"
border-right-width="0px" border-top-width="0px" font-size="9px"
padding-left="0px" border-style="solid" border-width="1pt"
border-color="white" padding-start="0px" padding-end="2px"
padding-before="0px" padding-after="0px" width="16%" display-align="center"
text-align="start" hyphenate="true">
