XML : Splitting function in xslt 1.0 not working

I have the following xml

  <?xml version="1.0" encoding="utf-8"?>  <Root>                       <Number>2</Number>                       <Vehicle>                          <V4Code>PP03340105</V4Code>                          <SourceCode>PP03340105</SourceCode>                          <DRCCode>PP03340105</DRCCode>                          <OptionalCode1>ANDREA WILLIAM|DWIGHT ROBINSON|04</OptionalCode1>                         </Vehicle>                    </Root>    

Trying to split with the method given below

  <xsl:stylesheet version="1.0"   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:output omit-xml-declaration="yes" indent="yes"/>     <xsl:template match="text()" name="split">    <xsl:param name="pText" select="Root/OptionalCode1"/>    <xsl:if test="string-length($pText)">     <xsl:if test="not($pText=.)">      <br />     </xsl:if>      <xsl:element name ="Name1">     <xsl:value-of select=      "substring-before(concat($pText,'|'),'|')"/>       </xsl:element>     <xsl:call-template name="split">      <xsl:with-param name="pText" select=       "substring-after($pText, '|')"/>     </xsl:call-template>    </xsl:if>   </xsl:template>  </xsl:stylesheet>    

output is just this :

Anyhelp is much appreciated please.I am not sure in what line i am making mistake. Since i am new to this xslt, not sure how to find the line in which i am making mistake too.

Output should be

  <Root>  <List1>Andrea William</List1>  <List2>Dwight Robinson</List2>  </Root>
