This stylesheet will scan forward over your input string:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="text"/>
<xsl:variable name="string" select="'c0 c1 c2 c3 c4'"/>
<xsl:variable name="delim" select="' '"/>
<xsl:template match="/">
<xsl:call-template name="wrapper">
<xsl:with-param name="string" select="$string"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="wrapper">
<xsl:param name="string"/>
<xsl:choose>
<!-- handle empty input -->
<xsl:when test=" $string = '' "/>
<!-- handle next token -->
<xsl:when test="contains($string, $delim)">
<xsl:call-template name="process">
<xsl:with-param name="substring" select="substring-before($string,$delim)"/>
</xsl:call-template>
<xsl:call-template name="wrapper">
<xsl:with-param name="string" select="substring-after($string,$delim)"/>
</xsl:call-template>
</xsl:when>
<!-- handle last token -->
<xsl:otherwise>
<xsl:call-template name="process">
<xsl:with-param name="substring" select="$string"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template name="process">
<xsl:param name="substring"/>
<xsl:text>RECEIVED SUBSTRING: </xsl:text>
<xsl:value-of select="$substring"/>
<xsl:text>
</xsl:text>
</xsl:template>
</xsl:stylesheet>
to produce the following output:
RECEIVED SUBSTRING: c0
RECEIVED SUBSTRING: c1
RECEIVED SUBSTRING: c2
RECEIVED SUBSTRING: c3
RECEIVED SUBSTRING: c4
