Re: Includes in LAS xml files

[J-M Epitalon <Jean-Marie.Epitalon@xxxxxxxxxx>]

Ben,

yes, I believe I can see what is wrong...

I guess that the entity you include should contain a valid start tag matched with
a valid end tag.

In your example, file Insitu_Air_Temperature.xml should contain all the three
lines:
  <Station_Pressure name="Station Pressure" units="hPa (mb)">
    <link match="/lasdata/grids/DGS_XYZT_grid"/>
   </Station_Pressure>

matching <Station_Pressure ...> start tag with   </Station_Pressure>

Did you try that ?
