I. XSLT 1.0 solution:

Here is one way to do this in XSLT 1.0 using only the xxx:node-set() extension function:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:ext="http://exslt.org/common" exclude-result-prefixes="ext">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="mark">
  <xsl:variable name="vrtfSplit">
   <xsl:apply-templates/>
  </xsl:variable>

  <xsl:for-each select="ext:node-set($vrtfSplit)/*">
   <processedItem>
    <xsl:value-of select="10 * ."/>
   </processedItem>
  </xsl:for-each>
 </xsl:template>

 <xsl:template match="text()" name="split">
  <xsl:param name="pText" select="."/>
   <xsl:if test="string-length($pText) >0">
    <item>
     <xsl:value-of select=
      "substring-before(concat($pText, ','), ',')"/>
    </item>

    <xsl:call-template name="split">
     <xsl:with-param name="pText" select=
     "substring-after($pText, ',')"/>
    </xsl:call-template>
   </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied to the following XML document:

<mark>1,2,3,4,5</mark>

The wanted, correct output (each item multiplied by 10) is produced:

<processedItem>10</processedItem>
<processedItem>20</processedItem>
<processedItem>30</processedItem>
<processedItem>40</processedItem>
<processedItem>50</processedItem>

II. XSLT 2.0 solution:

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:xs="http://www.w3.org/2001/XMLSchema"
  exclude-result-prefixes="xs">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="mark">
  <xsl:for-each select="tokenize(., ',')">
   <processedItem>
    <xsl:sequence select="10*xs:integer(.)"/>
   </processedItem>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>
