XSLT 1.0: string into array variable - xslt

Question

I have a variable as below:
<xsl:variable name="ARRAY">
One,Two,Three,Four
</xsl:variable>
With XSLT 2.0 I used tokenize functions and I set an array variable:
<xsl:variable name="tokenizedSample" select="tokenize($ARRAY,',')"/>
and get array value with:
<xsl:value-of select="$tokenizedSample[1]"/>
Unfortunately I must use XSLT 1.0 and I don't know as replace this situation...
I found some examples to create a template as below:
<xsl:template name="SimpleStringLoop">
<xsl:param name="input"/>
<xsl:if test="string-length($input) > 0">
<xsl:variable name="v" select="substring-before($input, ',')"/>
<field>
<xsl:value-of select="$v"/>
</field>
<xsl:call-template name="SimpleStringLoop">
<xsl:with-param name="input" select="substring-after($input, ',')"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
and calling this template as below:
<xsl:variable name="fields">
<xsl:call-template name="SimpleStringLoop">
<xsl:with-param name="input" select="$ARRAY"/>
</xsl:call-template>
</xsl:variable>
and accessing to this new array with:
<xsl:value-of select="$fields[1]"/>
but doesn't work.
How can I do?
I would like a XSLT 1.0 variable as array because I want read it with for example:
$newArray[1]
Thanks.

I don't see why you would define a variable that needs tokenizing, instead of defining it as "tokenized" to begin with.
In XSLT 1.0, this could be done as:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:my="http://www.example.com/my"
exclude-result-prefixes="my">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<my:items>
<item>One</item>
<item>Two</item>
<item>Three</item>
<item>Four</item>
</my:items>
<!-- the rest of the stylesheet -->
</xsl:stylesheet>
With this in place, you can do:
<xsl:value-of select="document('')/xsl:stylesheet/my:items/item[2]"/>
from anywhere in your stylesheet to retrieve "Two".
Of course, you could put the "array" into a variable:
<xsl:variable name="my-items" select="document('')/xsl:stylesheet/my:items/item" />
so that you can shorten the reference to:
<xsl:value-of select="$my-items[2]"/>
