Hi,
I am using XSLT -> FO to generate the PDF.
When the text in a column exceeds the size of the column and there are no spaces in the text - then the text runs over into the next cell or outside the table.
I want the text to be occupied within the same cell.
Thanx in Advance, Swetha
If possible truncate the extra letters. Use the length() and substring() functions of xslt. You can also provide a tooltip or something to show the whole text if you truncate it
You can split the text into words by inserting zero-width space characters (U+200B, HTML entity ​), then the line breaks will occur at these positions:
<xsl:template name="split_value">
<xsl:param name="value"/>
<xsl:param name="max_length"/>
<xsl:variable name="ret">
<xsl:value-of select="substring($value, 1, $max_length)"/>
<xsl:if test="string-length($value) > $max_length">
<xsl:value-of select="'​'"/>
<xsl:call-template name="split_value">
<xsl:with-param
name="value"
select="substring($value, $max_length + 1)"
/>
<xsl:with-param
name="max_length"
select="$max_length"
/>
</xsl:call-template>
</xsl:if>
</xsl:variable>
<xsl:value-of select="$ret"/>
</xsl:template>
Note: you might want to enhance the template so that it splits only pieces of text where no whitespace occurs between $max_length continuous characters.
Here's a test case.
Input XML:
<data>0123456789</data>
Stylesheet (generates HTML):
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
exclude-result-prefixes="xsl"
>
<xsl:template match="/">
<html>
<body
style="font-family: Arial; font-size: 12pt; font-weight: normal"
>
<table width="4cm">
<xsl:for-each select="/data">
<tr><td>
<xsl:call-template name="split_value">
<xsl:with-param
name="value"
select="text()"
/>
<xsl:with-param
name="max_length"
select="number(4)"
/>
</xsl:call-template>
</td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
