How to Skip segment based on a field value in XSLT - xslt

Question

I have an XML input which i have to map into a target structure
Here is the link to Fiddler: LINK

I have to write XSLT code so that node and subnodes only get copied and formatted with new field names when AttributeId = DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-SMTP_ADDR and corresponding Value != ''
How do i modify XSLT Code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:variable name="campaign" select="root/d/Campaign/CampaignId/text()" />
<xsl:template match="TargetGroupMemberAttributeData[AttributeId='DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-NAME_FIRST']">
<FIRST_NAME><xsl:value-of select="Value"/></FIRST_NAME>
</xsl:template>
<xsl:template match="TargetGroupMemberAttributeData[AttributeId='DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-NAME_LAST']">
<LAST_NAME><xsl:value-of select="Value" /></LAST_NAME>
<xsl:template match="CampaignTargetGroupMembers/ExecutionRunKey">
<CAMPAIGN_ID><xsl:copy-of select="$campaign"/></CAMPAIGN_ID>
</xsl:template>
<xsl:template match="TargetGroupMemberAttributeData[AttributeId='OUTBOUND_INTERACTION']">
<UUID><xsl:value-of select="Value" /></UUID>
</xsl:template>
</xsl:stylesheet>
The output Should be:
<?xml version="1.0" encoding="UTF-8"?><root>
<d>
<Campaign>
<CampaignId>0000000112</CampaignId>
<Name>Connected Water DMI Fail Test</Name>

To get the desired output, you can use the following stylesheet. But not all values could be derived from your source, so I put in some static values. I guess that you could fill in the rest.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="campaign" select="root/d/Campaign/CampaignId/text()" />
<xsl:mode on-no-match="shallow-copy" />
<xsl:strip-space elements="*" />
<xsl:template match="CampaignTargetGroupMembers | TargetGroupMemberAttributeData" />
<xsl:template match="CampaignTargetGroupMembers[TargetGroupMemberAttributeData[AttributeId='DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-SMTP_ADDR' and Value!='']]">
<xsl:copy>
<xsl:apply-templates select="#* | OutboundId | PackageId"/>
<CAMPAIGN_ID><xsl:value-of select="$campaign" /></CAMPAIGN_ID>
<Email><xsl:value-of select="TargetGroupMemberAttributeData[AttributeId='DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-SMTP_ADDR']/Value" /></Email>
<LAST_NAME><xsl:value-of select="TargetGroupMemberAttributeData[AttributeId='DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-NAME_LAST']/Value" /></LAST_NAME>
<FIRST_NAME><xsl:value-of select="TargetGroupMemberAttributeData[AttributeId='DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-NAME_FIRST']/Value"/></FIRST_NAME>
<TargetGroupMemberAttributeData>
<AttributeId>DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-INITIATIVE_ID</AttributeId>
<Value>0000000105,0000000092,0000000041,,0000000054,0000000076</Value>
<EdmTypeId><xsl:value-of select="TargetGroupMemberAttributeData[1]/EdmTypeId" /></EdmTypeId>
<OutboundId><xsl:value-of select="TargetGroupMemberAttributeData[1]/OutboundId" /></OutboundId>
</TargetGroupMemberAttributeData>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Its output is:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<d>
<Campaign>
<CampaignId>0000000112</CampaignId>
<Name>Connected Water DMI Fail Test</Name>
<MarketingAreaId>CXXGLOBAL</MarketingAreaId>
<SegmentationObject>SAP_CONTACT_ENGAGEMENT_SIN</SegmentationObject>
<ImplementationId>ZOC_EXPORT_ACOUSTIC</ImplementationId>
</Campaign>
<PackageId>47</PackageId>
<ExecutionStartDateTime>2021-06-30T15:28:49Z</ExecutionStartDateTime>
<ExecutionRunKey>42010A0350331EDBB6B6EDEF969FD623</ExecutionRunKey>
<CampaignTargetGroupMembers>
<OutboundId>E6713D258EAC1ADACE6AC905BB3ECF5E1CEF4776</OutboundId>
<PackageId>47</PackageId>
<CAMPAIGN_ID>0000000112</CAMPAIGN_ID>
<Email>rcgrymm#gmail.com</Email>
<LAST_NAME>Carmona</LAST_NAME>
<FIRST_NAME>Ruben</FIRST_NAME>
<TargetGroupMemberAttributeData>
<AttributeId>DA-_SAP_CF_CE_CONTACT_IA_ERP_CUST-INITIATIVE_ID</AttributeId>
<Value>0000000105,0000000092,0000000041,,0000000054,0000000076</Value>
<EdmTypeId>Edm.String</EdmTypeId>
<OutboundId>E6713D258EAC1ADACE6AC905BB3ECF5E1CEF4776</OutboundId>
</TargetGroupMemberAttributeData>
</CampaignTargetGroupMembers>
</d>
</root>
Which is as desired (with some static values which cannot be deduced from the input XML).
