Re: match string

Maybe I have found a solution. It works, at least with libxslt.
is this correct? I think is is rather a hack.

<!--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:otherwise>
				<xsl:call-template name="para.template">
				</xsl:call-template>
			</xsl:otherwise>

  </xsl:choose>
</xsl:template>

Hmmm... just after posting, I realized it's probably safer to use "normalize-space(.)", to ignore any leading whitespace:

<xsl:param name="split" select="3"/>
<xsl:template match="para">
<para><xsl:call-template name="splitwords"/></para>
</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>
