XSL-FO: Forced Wrap on Table Entries

I have a problem when I publish my modspecs for pdf (XSL-FO). My tables have problems when the contents of a cell overflow its column into the next. How to force a text break so that a new line is created instead?

I cannot manually insert zero-space characters, since the entries in the table are entered programmatically. I am looking for a simple solution that I can simply add to docbook_pdf.xsl (either as an attribute xsl: param or xsl :).

EDIT: This is where I am now:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" xmlns:fo="http://www.w3.org/1999/XSL/Format"> <xsl:import href="urn:docbkx:stylesheet"/> ...(the beginning of my stylesheet for pdf generation, eg header and footer content stuff) <xsl:template match="text()"> <xsl:call-template name="intersperse-with-zero-spaces"> <xsl:with-param name="str" select="."/> </xsl:call-template> </xsl:template> <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> </xsl:stylesheet>

At the same time, long words are successfully divided into table cells! Unfortunately, a side effect is that plain text in another place (for example, in interlinear X) now splits words so that they appear on separate lines. Is there a way to isolate the process described above with tables?

In long words, try inserting the character space width between the characters where the gap is allowed.

Since you are using XSLT 2.0:

 <xsl:template match="text()"> <xsl:value-of select="replace(replace(., '(\P{Zs})(\P{Zs})', '$1&#x200B;$2'), '([^\p{Zs}&#x200B;])([^\p{Zs}&#x200B;])', '$1&#x200B;$2')" /> </xsl:template>

This is using the escapes categories ( http://www.w3.org/TR/xmlschema-2/#nt-catEsc ) and not an explicit list of characters to match, but you can do it this way instead. It needs two replace() , because internal replace() can only insert a character between every second character. External replace() matches characters that are not space characters or a character added by internal replace() .

Insert after every thirteenth non-spatial character:

 <xsl:template match="text()"> <xsl:value-of select="replace(replace(., '(\P{Zs}{13})', '$1&#x200B;'), '&#x200B;(\p{Zs})', '$1')" /> </xsl:template>

The inner replace() inserts a character after every 13 non-spatial characters, and the outer replace() corrects it if the 14th character was a whitespace character.

If you use AH Formatter, you can use axf:word-break="break-all" to allow AH Formatter to break anywhere in the word. See https://www.antennahouse.com/product/ahf64/ahf-ext.html#axf.word-break .
