Hi,

I need advice. I would like to dynamicaly read XML fiel using XFMAP to create feature types and extract values. Here is my source XML:

<?xml version="1.0" encoding="UTF-8"?>

I would like to create feature type using davkaTable Name (/b:DataTableList/b:DavkaTable/b:Name) and each featuretype wil have own attributes defined in columnList section. I created following XFMAP file:

<xfMap>
    <feature-map multi-feature-construction="true">
        <note> construct an FME feature when we read the 'Feature' element. </note>
        <mapping match="b:DataTableList/b:DavkaTable">
            <feature-type>
                <extract expr="./b:Name"/>
            </feature-type>           
        </mapping>
    </feature-map>
      <feature-content-map>
          <mapping match="b:DataTableList/b:DavkaTable/b:RowList/b:Row/b:ColumnList/b:Column">
            <attributes>
                <attribute type="sequenced">
                    <name>
                        <extract expr="./b:Name"/>
                    </name>
                    <value>
                        <extract expr="./b:Value"/>
                    </value>
                </attribute>
            </attributes>
        </mapping>
  </feature-content-map> 
</xfMap>


Using this XFMAP I can create featuretypes structure, but I have problem to load values for each row. Only first row is taken into account instead 2 rows for featuretype dtCisTriedZnakKolaje and three rows for dtCisDoprUrc. Please, could you advice me, what is wrong ? Thank you very much.

Hi @radochudy, I think you have to implement the cardinality attribute in <structure> element, in order to extract the Row elements as list attribute. See here to learn more: Structure Element

By the way, why not use the regular XML reader or the XMLFragmenter with flattening options?
