Transformation using XSLT - xslt-1.0

Question

Need help to convert SOAP message to XML:
The element "externalID"can occur multiple time so based on "externalID" this element need to generate "Detail" tag in output XML.
Need some code sample to convert this SOAP message to desired output XML
Input SOAP Message:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:mem="http://example.com/vc/types/attachments">
<soapenv:Header/>
<soapenv:Body>
<mem:payRequest>
<payload>
<uuid>?</uuid>
<umi>?</umi>
<externalID>
<externalLineID></externalLineID>
<groupNo>?</groupNo>
<payeeCd>dfsdfsfd</payeeCd>
<paymntAmt>?</paymntAmt>
<acctCd>dfafa</acctCd>
<transID>fasf</transID>
<errCD>?</errCD>
<errMessage>?</errMessage>
</externalID>
<externalID>
<externalLineID>?</externalLineID>
<groupNo>?</groupNo>
<payeeCd>dfsdfsfd</payeeCd>
<paymntAmt>?</paymntAmt>
<acctCd>dfafa</acctCd>
<transID>fasf</transID>
<errCD>?</errCD>
<errMessage>?</errMessage>
</externalID>
<errCD>?</errCD>
<errMessage>?</errMe`enter code here`ssage>
</payload>
</mem:payRequest>
</soapenv:Body>
</soapenv:Envelope>

I'd suggest you try it along these lines:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<payRequest>
<xsl:for-each select="//externalID">
<Detail>
<uuid>
<xsl:value-of select="../uuid"/>
</uuid>
<umd>
<xsl:value-of select="../umi"/>
</umd>
<claimNumber>
<xsl:value-of select="XYZ"/>
</claimNumber>
<claimLineNumber>
<xsl:value-of select="externalLineID"/>
</claimLineNumber>
<dd>
<xsl:value-of select="XYZ"/>
</dd>
<claimStatus>
<xsl:value-of select="XYZ"/>
</claimStatus>
<clientNumber>
<xsl:value-of select="XYZ"/>
</clientNumber>
<payMode>
<xsl:value-of select="XYZ"/>
</payMode>
<paymentAmount>
<xsl:value-of select="paymntAmt"/>
</paymentAmount>
<accountCode>
<xsl:value-of select="XYZ"/>
</accountCode>
<transactionId>
<xsl:value-of select="transID"/>
</transactionId>
<errorCode>
<xsl:value-of select="errCD"/>
</errorCode>
<returnCode>
<xsl:value-of select="XYZ"/>
</returnCode>
</Detail>
</xsl:for-each>
</payRequest>
</xsl:template>
</xsl:stylesheet>
You did not provide any information regarding which source nodes are supposed to provide the data for the result. I have tried to guess a few and used XYZ as a placeholder for the others.
Note: you should never have to use a hack like *[local-name()='externalID'].
