Change a string in xml into an array in xml easily - arrays

Question

I was wondering if anyone knew if there was a simple way to change all of my strings in my xml file to arrays?
Example:
//This is the string I need to change:
<string name="sample1">value1, value2, value3, value4, value5</string>
//This is the way I need it to be:
<array name="sample1">
<item>value1</item>
<item>value2</item>
<item>value3</item>
<item>value4</item>
<item>value5</item>
</array>
My problem is not that I do not know how to manually do it. But I am looking for a way to simulate this process more easily because I have 120 strings with 25-90 values in each.
A good example would be converting multiple images extentions with a single click using an add-on to GIMP that simulates that process for you for each image.
Would anyone who understands what I am asking, know a way to do this for string to array?

This XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<array>
<xsl:attribute name="name">
<xsl:value-of select="string/#name"/>
</xsl:attribute>
<xsl:apply-templates/>
</array>
</xsl:template>
<xsl:template match="string/text()" name="tokenize">
<xsl:param name="text" select="."/>
<xsl:param name="sep" select="','"/>
<xsl:choose>
<xsl:when test="not(contains($text, $sep))">
<item>
<xsl:value-of select="normalize-space($text)"/>
</item>
</xsl:when>
<xsl:otherwise>
<item>
<xsl:value-of select="normalize-space(substring-before($text, $sep))"/>
</item>
<xsl:call-template name="tokenize">
<xsl:with-param name="text" select="substring-after($text, $sep)"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
applied to this XML:
<?xml version="1.0" encoding="UTF-8"?>
<string name="sample1">value1, value2, value3, value4, value5</string>
gives this output:
<?xml version="1.0" encoding="UTF-8"?>
<array name="sample1">
<item>value1</item>
<item>value2</item>
<item>value3</item>
<item>value4</item>
<item>value5</item>
</array>
The XSLT is using a recursive template going through your string values and splitting them at the comma.

This can be done with XSLT 2.0 as simply as:
<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="/*">
<array name="{#name}">
<xsl:for-each select="tokenize(., ',\s*')">
<item><xsl:value-of select="."/></item>
</xsl:for-each>
</array>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the provided XML document:
<string name="sample1">value1, value2, value3, value4, value5</string>
the wanted, correct result is produced:
<array name="sample1">
<item>value1</item>
<item>value2</item>
<item>value3</item>
<item>value4</item>
<item>value5</item>
</array>
