Maybe I have found a solution. It works, at least with libxslt.
is this correct? I think is is rather a hack.
Didn't my solution work? I think your templates are correct but I'm not
sure if they will produce correct results for paragraphs with 3 words or
less. Also, I have the impression that they will only display the first
3 words and skip the rest?
<!--Select the first paragraph of all chapters-->
<xsl:template match="//chapter/section[1]/para[1]" priority="1">
<xsl:call-template name="first_line">
<xsl:with-param name="string" select="."/>
</xsl:call-template>
</xsl:template>
<!--Select all other paragraphs-->
<xsl:template match="//para">
<xsl:call-template name="para.template">
</xsl:call-template>
</xsl:template>
<xsl:template name="first_line">
<xsl:param name="string"/>
<xsl:param name="string2"/>
<xsl:param name="string3"/>
<xsl:choose>
<!--are there any spaces???-->
<xsl:when test="contains($string, ' ')">
<div>
<b>
<!--1st word-->
<xsl:value-of
select="substring-before($string,' ')"/>
<!--give back the space-->
<xsl:text> </xsl:text>
<!--2nd word-->
<xsl:value-of select="substring-before(
substring-after ($string, ' '), ' ')"/>
<!--give back the space-->
<xsl:text> </xsl:text>
<!--3rd word-->
<xsl:value-of select="substring-before(
substring-after ( substring-after ($string, ' '), ' '),' ')"/>
<!--give back the space-->
<xsl:text> </xsl:text>
</b>
</div>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="para.template">
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I don't know what your template name="para.template" does, but if you
only want to split the words on the first paragraph of every chapter,
and just copy all the others, you could do with an identity template and
a match like David suggested:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:param name="split" select="3"/>
<!-- identity template: copy all elements -->
<xsl:template match="*">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<!-- override on first paragraph of each chapter -->
<xsl:template match="chapter/section[1]/para[1]//text()[1]">
<xsl:call-template name="splitwords"/>
</xsl:template>
<xsl:template name="splitwords">
<xsl:param name="i" select="0"/>
<xsl:param name="str1" select="''"/>
<xsl:param name="str2" select="normalize-space(.)"/>
<xsl:choose>
<xsl:when test="$i = $split">
<b><xsl:value-of select="$str1"/></b>
<xsl:value-of select="$str2"/>
</xsl:when>
<xsl:otherwise>
<xsl:choose>
<xsl:when test="contains($str2,' ')">
<xsl:call-template name="splitwords">
<xsl:with-param name="i" select="$i+1"/>
<xsl:with-param name="str1"
select="concat($str1,substring-before($str2,' '),' ')"/>
<xsl:with-param name="str2"
select="substring-after($str2,' ')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="splitwords">
<xsl:with-param name="i" select="$split"/>
<xsl:with-param name="str1"
select="concat($str1,$str2)"/>
<xsl:with-param name="str2" select="''"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
