Problem getting xslt transform to work

Question

I have the following ABAP Xslt  transformation
<xsl:transform
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:sap="http://www.sap.com/sapxsl" version="1.0"
>
<xsl:strip-space elements="*"/>
     <xsl:template match="/">
          <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
               <asx:values>
                    <ALLIR_REIKNINGAR>
                         <xsl:apply-templates select="//Invoice"/>   
                    </ALLIR_REIKNINGAR>
               </asx:values>
          </asx:abap>
     </xsl:template>
    <xsl:template match="Invoice">
    <REIKNINGUR>
        <REIKN_NUMER>
            <xsl:value-of select="cbc:ID"/>           
        </REIKN_NUMER>
        <REIKN_AFRIT>
            <xsl:value-of select="cbc:CopyIndicator"/>
        </REIKN_AFRIT>
        <REIKN_UTGAFUDAGS>
            <xsl:value-of select="cbc:IssueDate"/>
        </REIKN_UTGAFUDAGS>
        <REIKN_MYNT>
            <xsl:value-of select="cbc:DocumentCurrencyCode"/>
        </REIKN_MYNT>
        <REIKN_TIMABIL_FRA>
            <xsl:value-of select="cac:InvoicePeriod/cbc:StartDate"/>
        </REIKN_TIMABIL_FRA>
        <REIKN_TIMABIL_TIL>
            <xsl:value-of select="cac:InvoicePeriod/cbc:EndDate"/>
        </REIKN_TIMABIL_TIL>
    </REIKNINGUR>
    </xsl:template>
</xsl:transform>
And the following XML input file
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="vodafone_xslt_namespace.xslt"?>
<Invoice
xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"

     <cbc:CopyIndicator>false</cbc:CopyIndicator>
     <cbc:IssueDate>2011-12-31</cbc:IssueDate>
     <cbc:InvoiceTypeCode listID="UN/ECE 1001 Restricted" listAgencyID="NES">380</cbc:InvoiceTypeCode>
     <cbc:Note languageID="IS">Company name</cbc:Note>
     <cbc:DocumentCurrencyCode listID="ISO 4217 Alpha">ISK</cbc:DocumentCurrencyCode>
     <cbc:AccountingCost>2001523</cbc:AccountingCost>
     <cac:InvoicePeriod>
          <cbc:StartDate>2011-12-01</cbc:StartDate>
          <cbc:EndDate>2011-12-31</cbc:EndDate>
     </cac:InvoicePeriod>
</Invoice>
My problem is that this transformation does not work unless I completly strip out the namespace parts i.e. cbc:
How can I get the parser to read the tags with namespace part. And if the parser can not handle namespace in XML how can I go about reding the data into sap ?

I think you are trying convert the xml to an internal table because of // in apply-templates, then you need to change last XSLT program and include <item> tag inside the <xsl:template match="inv:Invoice">  template, see updated XSLT bellow.
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:inv="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
xmlns:qdt="urn:oasis:names:specification:ubl:schema:xsd:QualifiedDatatypes-2"
xmlns:udt="urn:un:unece:uncefact:data:specification:UnqualifiedDataTypesSchemaModule:2"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ccts="urn:un:unece:uncefact:documentation:2"
xmlns:stat="urn:oasis:names:specification:ubl:schema:xsd:DocumentStatusCode-1.0"
xmlns:clm5639="urn:un:unece:uncefact:codelist:specification:5639:1988"
xmlns:clm54217="urn:un:unece:uncefact:codelist:specification:54217:2001"
xmlns:clm66411="urn:un:unece:uncefact:codelist:specification:66411:2001"
xmlns:clmIANAMIMEMediaType="urn:un:unece:uncefact:codelist:specification:IANAMIMEMediaType:2003"
xmlns:sapxsl="http://www.sap.com/sapxsl"
version="1.0">
  <xsl:strip-space elements="*"/>
  <xsl:strip-space elements="*"/>
  <xsl:template match="/">
    <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
      <asx:values>
        <ALLIR_REIKNINGAR>
          <xsl:apply-templates select="//inv:Invoice"/>
        </ALLIR_REIKNINGAR>
      </asx:values>
    </asx:abap>
  </xsl:template>
  <xsl:template match="inv:Invoice">
    <item>
    <REIKNINGUR>
      <REIKN_NUMER>
        <xsl:value-of select="cbc:ID"/>
      </REIKN_NUMER>
      <REIKN_AFRIT>
        <xsl:value-of select="cbc:CopyIndicator"/>
      </REIKN_AFRIT>
      <REIKN_UTGAFUDAGS>
        <xsl:value-of select="cbc:IssueDate"/>
      </REIKN_UTGAFUDAGS>
      <REIKN_MYNT>
        <xsl:value-of select="cbc:DocumentCurrencyCode"/>
      </REIKN_MYNT>
      <REIKN_TIMABIL_FRA>
        <xsl:value-of select="cac:InvoicePeriod/cbc:StartDate"/>
      </REIKN_TIMABIL_FRA>
      <REIKN_TIMABIL_TIL>
        <xsl:value-of select="cac:InvoicePeriod/cbc:EndDate"/>
      </REIKN_TIMABIL_TIL>
    </REIKNINGUR>
   </item>
  </xsl:template>
</xsl:transform>
According to the XSLT program you need dclare an itab like this:
DATA: BEGIN OF ls_reikningur,
      reikn_numer(10) TYPE c,
      END OF ls_reikningur.
DATA: BEGIN OF ls_invoice,
      reikningur LIKE ls_reikningur,
      END OF ls_invoice.
DATA: lt_invoice LIKE TABLE OF ls_invoice.
And finally you need a call transformation in your abap code like this:
DATA: root_error TYPE REF TO cx_root.
DATA: lv_mess TYPE string.
TRY.
    CALL TRANSFORMATION  zinvoice
       SOURCE XML lv_xml
       RESULT allir_reikningar = lt_invoice.
  CATCH cx_root INTO root_error.
    lv_mess = root_error->if_message~get_text( ).
    WRITE lv_mess.
ENDTRY.
