Writing XSLT to perform transformation from XML to ABAP

Question

Hi,
I've been struggling quite a bit with XSLT. I read several old discussions regarding transformations using ST and XSLT but I haven't been able to solve my problem.
I have a requirement to build a program to convert XML to an internal table.
I've been able to do it for smaller XMLs, but whenever I try to apply the same logic to a bigger XML it simply just doesn't work. I'm almost certain it has something to do with the way I wrote the XSLT but I haven't been able to figure out what.
The XML I have to read from goes something like this:
<?xml version="1.0" encoding="WINDOWS-1252"?>
-<AuditFile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:OECD:StandardAuditFile-Tax:PT_1.02_01">
     -<Header xmlns="urn:OECD:StandardAuditFile-Tax:PT_1.02_01">
          <AuditFileVersion>1.02_01</AuditFileVersion>
               <CompanyID>50002</CompanyID>
               <TaxRegistrationNumber>5000</TaxRegistrationNumber>
               <TaxAccountingBasis>F</TaxAccountingBasis>
               <CompanyName>Company</CompanyName>
               <BusinessName>Business</BusinessName>
               -<CompanyAddress>
                    <AddressDetail>Address</AddressDetail>
                    <City>city</City>
                    <PostalCode>333333</PostalCode>
                    <Country>PT</Country>
               </CompanyAddress>
               <FiscalYear>2013</FiscalYear>
               <StartDate>2013-07-01</StartDate>
               <EndDate>2013-07-31</EndDate>
               <CurrencyCode>EUR</CurrencyCode>
               <DateCreated>2013-08-02</DateCreated>
               <TaxEntity>Global</TaxEntity>
               <ProductCompanyTaxID>00</ProductCompanyTaxID>
               <SoftwareCertificateNumber>00</SoftwareCertificateNumber>
               <ProductID>product</ProductID>
               <ProductVersion>00</ProductVersion>
              <Email>email@com</Email>
               <Website>www.s.pt</Website>
     </Header>
     -<MasterFiles xmlns="urn:OECD:StandardAuditFile-Tax:PT_1.02_01">
          -<Customer>
               <CustomerID>1</CustomerID>
               <AccountID>ID</AccountID>
               <CustomerTaxID>999999990</CustomerTaxID>
               <CompanyName>Desconhecido</CompanyName>
               -<BillingAddress>
                    <AddressDetail>Desconhecido</AddressDetail>
                    <City>Desconhecido</City>
                    <PostalCode>0000-000</PostalCode>
                    <Country>PT</Country>
               </BillingAddress>
               <SelfBillingIndicator>0</SelfBillingIndicator>
          </Customer>
          -<Customer>
               <CustomerID>2</CustomerID>
               <AccountID>Desconhecido</AccountID>
               <CustomerTaxID>571</CustomerTaxID>
               <CompanyName>Company</CompanyName>
               -<BillingAddress>
                    <AddressDetail>detail</AddressDetail>
                    <City>city</City>
                    <PostalCode>0000-000</PostalCode>
                   <Country>PT</Country>
           </BillingAddress>
          <SelfBillingIndicator>0</SelfBillingIndicator>
     </Customer>
...and so on
And the XSLT I've written so far is something like this:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   <xsl:output encoding="iso-8859-1" indent="yes" method="xml" version="1.0"/>
   <xsl:strip-space elements="*"/>
   <xsl:template match="/">
     <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
       <asx:values>
         <ICUSTOMER>
           <xsl:apply-templates select="//Customer"/>
         </ICUSTOMER>
       </asx:values>
     </asx:abap>
   </xsl:template>
   <xsl:template match="Customer">
     <item>
       <CUSTOMER_ID>
         <xsl:value-of select="CustomerID"/>
       </CUSTOMER_ID>
       <ACCOUNT_ID>
         <xsl:value-of select="AccountID"/>
       </ACCOUNT_ID>
       <CUSTOMERTAX_ID>
         <xsl:value-of select="CustomerTaxID"/>
       </CUSTOMERTAX_ID>
       <COMPANYNAME>
         <xsl:value-of select="CompanyName"/>
       </COMPANYNAME>
       <ADDRESSDETAIL>
         <xsl:value-of select="BillingAddress/AddressDetail"/>
       </ADDRESSDETAIL>
       <CITY>
         <xsl:value-of select="BillingAddress/City"/>
       </CITY>
        <POSTALCODE>
         <xsl:value-of select="BillingAddress/PostalCode"/>
       </POSTALCODE>
        <COUNTRY>
         <xsl:value-of select="BillingAddress/Country"/>
       </COUNTRY>
       <SELFBILLINGINDICATOR>
         <xsl:value-of select="SelfBillingIndicator"/>
       </SELFBILLINGINDICATOR>
     </item>
   </xsl:template>
</xsl:transform>
Like I said, I'm almost certain that the problem is with the XSLT, as it returns an empty table / ALV. I've used this method before and it worked...
Any thoughts?
Thank you

Hello Goncalo,
I think, there are two problems:
1) The xmlns declaration within your xml is a problem for the SAP XSLT Processor.
2) I have written a similar XSLT-report, which performs directly with your data. Perhaps this is not necessary if 1) is solved:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
   <xsl:output encoding="iso-8859-1" indent="yes" method="xml" version="1.0"/>
   <xsl:strip-space elements="*"/>
   <xsl:template match="AuditFile">
     <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
       <asx:values>
          <xsl:apply-templates select="MasterFiles"/>
       </asx:values>
     </asx:abap>
   </xsl:template>
   <xsl:template match="MasterFiles">
         <ICUSTOMER>
           <xsl:apply-templates select="./Customer"/>
         </ICUSTOMER>
   </xsl:template>
   <xsl:template match="Customer">
       <CUSTOMER_ID>
         <xsl:value-of select="CustomerID"/>
       </CUSTOMER_ID>
       <ACCOUNT_ID>
         <xsl:value-of select="AccountID"/>
       </ACCOUNT_ID>
       <CUSTOMERTAX_ID>
         <xsl:value-of select="CustomerTaxID"/>
       </CUSTOMERTAX_ID>
   </xsl:template>
</xsl:transform>
Kind regards,
Hendrik
