Split Attribute using ; as delimiter in XSLT - xslt

Question

How to split an elements using ; as delimiter.my requirement is like below.
input:
<Element1>C:KEK39519US; U:085896395195; A:K39519US; B:S2345843</Element1>
output:
<CustItem>KEK39519US</CustItem>
<UNumber>085896395195</UNumber>
<ANumber>K39519US</ANumber>
<BNumber>S2345843</BNumber>
the input is every time not same.some times it comes like C:KEK39519US; U:085896395195; B:S2345843
some time like this C:KEK39519US; A:K39519US; B:S2345843
sometime like this U:085896395195; A:K39519US;
sometime like this C:KEK39519US; U:085896395195; A:K39519US;

To solve this in XSLT 1.0 you may need a named template which recursively calls itself. The template will process of the string before the first semi-colon, and output the element accordingly. It will then recursively call itself with the remaining part of the string after this semi-colon (if there is one)
Here is the full XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="Element1">
<xsl:call-template name="outputElements">
<xsl:with-param name="list" select="." />
</xsl:call-template>
</xsl:template>
<xsl:template name="outputElements">
<xsl:param name="list"/>
<xsl:variable name="first" select="normalize-space(substring-before(concat($list, ';'), ';'))"/>
<xsl:variable name="remaining" select="normalize-space(substring-after($list, ';'))"/>
<xsl:call-template name="createElement">
<xsl:with-param name="element" select="$first" />
</xsl:call-template>
<!-- If there are still elements left in the list, call the template recursively -->
<xsl:if test="$remaining">
<xsl:call-template name="outputElements">
<xsl:with-param name="list" select="$remaining"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
<xsl:template name="createElement">
<xsl:param name="element"/>
<xsl:variable name="elementName">
<xsl:choose>
<xsl:when test="substring-before($element, ':') = 'C'">CustItem</xsl:when>
<xsl:otherwise><xsl:value-of select="concat(substring-before($element, ':'), 'Number')" /></xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:element name="{$elementName}">
<xsl:value-of select="substring-after($element, ':')" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
When applied to you XML, the following is output
<CustItem>KEK39519US</CustItem>
<UNumber>085896395195</UNumber>
<ANumber>K39519US</ANumber>
<BNumber>S2345843</BNumber>
Note the use of Attribute Value Templates in specifying the name of each new element.
