I have a rather complicated xslt sheet transforming one xml format to another using templates. However, in the resulting xml, I need to have all the empty elements excluded. How is that done?
This is how the base xslt looks like:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:far="http://www.itella.com/fargo/fargogate/" xmlns:a="http://tempuri.org/XMLSchema.xsd" xmlns:p="http://tempuri.org/XMLSchema.xsd">
<xsl:import href="TransportCDMtoFDM_V0.6.xsl"/>
<xsl:import href="ConsignmentCDMtoFDM_V0.6.xsl"/>
<xsl:template match="/">
<InboundFargoMessage>
<EdiSender>
<xsl:value-of select="TransportInformationMessage/SenderId"/>
</EdiSender>
<EdiReceiver>
<xsl:value-of select="TransportInformationMessage/RecipientId"/>
</EdiReceiver>
<EdiSource>
<xsl:value-of select="TransportInformationMessage/Waybill/Parties/Consignor/Id"/>
</EdiSource>
<EdiDestination>FARGO</EdiDestination>
<Transportations>
<xsl:for-each select="TransportInformationMessage/TransportUnits/TransportUnit">
<xsl:call-template name="transport"/>
</xsl:for-each>
<xsl:for-each select="TransportInformationMessage/Waybill/TransportUnits/TransportUnit">
<xsl:call-template name="transport"/>
</xsl:for-each>
<xsl:for-each select="TransportInformationMessage/Waybill">
<EdiImportTransportationDTO>
<Consignments>
<xsl:for-each select="Shipments/Shipment">
<xsl:call-template name="consignment"/>
</xsl:for-each>
</Consignments>
<EdiTerminalDepartureTime>
<xsl:value-of select="DatesAndTimes/EstimatedDepartureDateTime"/>
<xsl:value-of select="DatesAndTimes/DepartureDateTime"/>
</EdiTerminalDepartureTime>
<EdiAgentTerminalArrivalDate>
<xsl:value-of select="DatesAndTimes/EstimatedArrivalDateTime"/>
<xsl:value-of select="DatesAndTimes/ArrivalDateTime"/>
</EdiAgentTerminalArrivalDate>
<EdiActivevehicle>
<xsl:value-of select="Vehicle/TransportShiftNumber"/>
</EdiActivevehicle>
<EdiConveyerZipCodeTown><xsl:text> </xsl:text></EdiConveyerZipCodeTown>
</EdiImportTransportationDTO>
</xsl:for-each>
</Transportations>
</InboundFargoMessage>
</xsl:template>
</xsl:stylesheet>
What needs to be added, so that empty elements are left out?
For example, a snippet from the resulting xml:
<?xml version="1.0" encoding="UTF-8"?>
<InboundFargoMessage xmlns:p="http://tempuri.org/XMLSchema.xsd"
xmlns:far="http://www.itella.com/fargo/fargogate/"
xmlns:a="http://tempuri.org/XMLSchema.xsd">
<EdiSender>XXXX</EdiSender>
<EdiReceiver>YYYY</EdiReceiver>
<EdiSource>TR/BAL/IST</EdiSource>
<EdiDestination>FARGO</EdiDestination>
<Transportations>
<EdiImportTransportationDTO>
<Consignments>
<EdiImportConsignmentDTO>
<ConsignmentLines>
<EdiImportConsignmentLineDTO>
<DangerousGoodsItems>
<EdiImportDangerGoodsItemDTO>
<EdiKolliTypeOuter/>
<EdiKolliTypeInner/>
<EdiTechnicalDescription/>
<EdiUNno/>
<EdiClass/>
<EdiDangerFactor/>
<EdiEmergencyTemperature/>
</EdiImportDangerGoodsItemDTO>
</DangerousGoodsItems>
<BarCodes>
<EdiImportConsignmentLineBarcodeDTO/>
</BarCodes>
<EdiNumberOfPieces>00000002</EdiNumberOfPieces>
<EdiGrossWeight>0.000</EdiGrossWeight>
<EdiHeight/>
<EdiWidth/>
<EdiLength/>
<EdiGoodsDescription/>
<EdiMarkingAndNumber/>
<EdiKolliType>road</EdiKolliType>
<EdiCbm/>
<EdiLdm/>
</EdiImportConsignmentLineDTO>
That really needs to be:
<?xml version="1.0" encoding="UTF-8"?>
<InboundFargoMessage xmlns:p="http://tempuri.org/XMLSchema.xsd"
xmlns:far="http://www.itella.com/fargo/fargogate/"
xmlns:a="http://tempuri.org/XMLSchema.xsd">
<EdiSender>XXXX</EdiSender>
<EdiReceiver>YYYY</EdiReceiver>
<EdiSource>TR/BAL/IST</EdiSource>
<EdiDestination>FARGO</EdiDestination>
<Transportations>
<EdiImportTransportationDTO>
<Consignments>
<EdiImportConsignmentDTO>
<ConsignmentLines>
<EdiImportConsignmentLineDTO>
<DangerousGoodsItems/>
<BarCodes/>
<EdiNumberOfPieces>00000002</EdiNumberOfPieces>
<EdiGrossWeight>0.000</EdiGrossWeight>
<EdiKolliType>road</EdiKolliType>
</EdiImportConsignmentLineDTO>
In other words: Empty elements should be left out.
