Question

Hi need to create tags only if values are found in the XML

I am converting XML to XML using XSL
my problem is to create tags only if values are found in the input XML .
I referred many things and created XSL but not working could you please help me .
Thanks!

Input XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href= "D:\Vignesh\Task\RFC\FIS107_24Feb1\MyChanges\XSL SHEET\ThirdIP-HostIP.xsl"?>
<rsm:Waybill     xmlns:ccts="urn:un:unece:uncefact:documentation:standard:CoreComponentsTechnicalSpecificati    on:2" xmlns:udt="urn:un:unece:uncefact:data:standard:UnqualifiedDataType:8"
xmlns:rsm="iata:waybill:1" xmlns:ram="iata:datamodel:3">
<rsm:MessageHeaderDocument>
<ram:ID>01463898855</ram:ID> 
<rsm:MessageHeaderDocument>
</rsm:Waybill>

My XSL:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"     xmlns:ccts="urn:un:unece:uncefact:documentation:standard:CoreComponentsTechnicalSpecification:2"             xmlns:udt="urn:un:unece:uncefact:data:standard:UnqualifiedDataType:8"
         xmlns:rsm="iata:waybill:1"           xmlns:ram="iata:datamodel:3">
<xsl:output method="xml" indent="yes" ></xsl:output>

<xsl:template match="/">

    <xsl:if test="rsm:Waybill/rsm:MessageHeaderDocument/ram:ID"> 
        <xsl:text><![CDATA[<ROUTING>]]></xsl:text>
        <xsl:text><![CDATA[<ORIGIN>]]></xsl:text>
        <xsl:text><![CDATA[ <STATION> ]]></xsl:text>
        <xsl:value-of select="/rsm:Waybill/rsm:MasterConsignment/ram:OriginLocation/ram:ID"/>
        <xsl:text><![CDATA[</STATION> ]]></xsl:text>
        <xsl:text><![CDATA[</ORIGIN>]]></xsl:text>
    </xsl:if>

</xsl:template>
</xsl:stylesheet>

My output will be like
if value is in ram:ID then:

<ROUTING>
    <ORIGIN>
    <STATION>
        01463898855
    <STATION>
    </ORIGIN>
</ROUTING>

iF NOT THEN : no tags should be created

Answer 1

If you change your the line

<xsl:if test="rsm:Waybill/rsm:MessageHeaderDocument/ram:ID">

into

<xsl:if test="rsm:Waybill/rsm:MessageHeaderDocument/ram:ID and rsm:Waybill/rsm:MessageHeaderDocument/ram:ID != ''">

that should also test if there is a value for ram:ID
