Simple Transformation - ignore attribute in element

[JanBraendgaard]

I am trying to create a Simple Transformation, but am stuck with the issue of having to ignore an attribute in the root element.

This is my XML data:

<?xml version="1.0" encoding="utf-8"?>
<ExportData xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="PostProcessor.SaveToXML" rootItemNumber="503620-000">
  <TimeStamp>2021-12-22T09:30:42.927665+01:00</TimeStamp>
  <Items>
    <Item>
      <ItemNumber type="String" value="061243-JBP"/>
      <VersionNumber type="Numeric" value="9"/>
    </Item>
  </Items>
</ExportData>

I would like to ignore or skip the attribute "rootItemNumber".

I'm using the ST code below.

<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates" xmlns:ddic="http://www.sap.com/abapxml/types/dictionary" xmlns:def="http://www.sap.com/abapxml/types/defined">
  <tt:root name="EXPORTDATA" type="ddic:ZCA_EXPORTDATA"/>
  <tt:template>
    <ExportData xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" rootItemNumber="503620-000" xmlns="NTI.Vault.Pro.BOMExport.PostProcessor.SaveToXML">
      <TimeStamp tt:value-ref=".EXPORTDATA.TIMESTAMP"/>
      <Items>
        <tt:loop ref=".EXPORTDATA.ITEM">
          <Item>
            <ItemNumber>
              <tt:attribute name="value" value-ref="ITEMNUMBER"/>
            </ItemNumber>
            <VersionNumber>
              <tt:attribute name="value" value-ref="VERSIONNUMBER"/>
            </VersionNumber>
          </Item>
        </tt:loop>
      </Items>
    </ExportData>
  </tt:template>
</tt:transform>

Just this?

            <ItemNumber>
              <tt:cond>
                <tt:attribute name="value"/>
              </tt:cond>
            </ItemNumber>

Hello sandra.rossi

I changed the attributes to conditional as you suggested. But this throws an error with "System expected element '<ExportData>'".

I think that this is because the ST code has no attributes in the <ExportData> element, and the XML contains four attributes in the element?

<tt:transform xmlns:tt="http://www.sap.com/transformation-templates" xmlns:ddic="http://www.sap.com/abapxml/types/dictionary" xmlns:def="http://www.sap.com/abapxml/types/defined" >
  <tt:root name="EXPORTDATA" type="ddic:ZCA_VAULT_EXPORTDATA"/>
  <tt:template>
<!--    <ExportData xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" rootItemNumber="503620-000" xmlns="SaveToXML">-->
    <ExportData>
      <tt:cond>
        <tt:attribute name="xsd"/>
        <tt:attribute name="xsi"/>
        <tt:attribute name="rootItemNumber" value-ref=".EXPORTDATA.ROOTITEMNUMBER"/>
        <tt:attribute name="xmlns"/>
      </tt:cond>

You don't need to indicate <tt:attribute...> for the attributes defining the namespaces.

You probably have an issue with the element <ExportData> which belongs to the namespace URI "SaveToXML".

    ...
    <xyz:ExportData xmlns:xyz="SaveToXML" >
      ...

Thank you sandra.rossi ,

This led me on the right track. And now it works. I added namespace to the elements.

And I also noticed that the test-XML-file I had been supplied with was missing three additional elements, that I had expected in the ST program. This also led me astray 🙂
