I tried using XMLFragmenter to extract the GML and follow up by GeometryExtractor. 

However I can't extract the geometry.

I then tried to create a WKT from the posList, but it seems redundant. 

The extracted GML:

<?xml version="1.0" encoding="UTF-16"?><ns46:Geometry xmlns:ns46="http://standardit.tapio.fi/schemas/forestData/WorkingSiteOperational">
            <ns7:polygonProperty xmlns:ns7="http://www.opengis.net/gml">
              <gml:Polygon srsDimension="2" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:sch="http://www.ascc.net/xml/schematron" xmlns:gml="http://www.opengis.net/gml">
  <gml:exterior>
    <gml:LinearRing srsDimension="2">
      <gml:posList>9.427851579 56.448124911 9.427915952 56.447846212 9.428527496 56.448095262 9.427851579 56.448124911</gml:posList>
    </gml:LinearRing>
  </gml:exterior>
</gml:Polygon>
            </ns7:polygonProperty>
          </ns46:Geometry>

If you have extracted the gml, it is a geometry replacer you need to build the geometries

Hi @mathiku​ 

You can also try using the GML reader to read the snippet and create the geometries. I have attached an example workspace using this approach. I hope it helps.

Thanks - that's a great method.

I need to run it on a server, it's not time critical, but I suspect that the AttributeFileWriter adds a lot of overhead.

Do you see other ways, preferably keeping it in attributes.

Sorry.

I read your response too fast.

I tried the geometryreplacer.

Works like a charm :)

Thanks for the help.
