XSLT: reading value as a list or array

I have an xml element: 

<myElement>item1 item2 item3</myElement>

I want to use XSLT to transform it to: 

<newElement>item1</newElement>  
<newElement>item2</newElement>
<newElement>item3</newElement>

How woudl the xslt look? I am more interested in how to loop though the list of myElement or how to get it to become a list or variable.

Please advise.

In XSLT 2.0 it's easier:

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

 <xsl:template match="myElement">
   <xsl:for-each select="tokenize(., '\s+')">
     <newElement><xsl:value-of select="."/></newElement>
   </xsl:for-each>
 </xsl:template>

</xsl:stylesheet>

This transformation:

<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()[contains(., ' ')]" name="tokenize">
  <xsl:param name="pText" select="."/>

  <xsl:if test="string-length($pText)">
   <newElement>
    <xsl:value-of select=
     "substring-before(concat($pText,' '),' ')"/>
   </newElement>

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

when applied on the provided XML document:

<myElement>item1 item2 item3</myElement>

produces the wanted, correct result:

<newElement>item1</newElement>
<newElement>item2</newElement>
<newElement>item3</newElement>
