Re: Includes in LAS xml files
Hello Jean-Marie,
I tried you idea and it works! However, it negates what I'm trying to accom
plish!!
I don't want to include the second line ( <link match="/lasdata/grids/DGS_XY
ZT_grid"/> ) in the xml include file, because it has to be unique for each
file. I have about 200 sets of automated weather station time series data f
rom different locations. This will result in my creating 200 files like CEO
P_Insitu_Surface_Mongolia_DGS.xml all of which have the same set of 19 vari
ables (e.g. Air_Temperature), but all of which have a different station name
(i.e. the "DGS" part, and all have a different lat/lon location). The stru
cture of my CEOP_Insitu_Surface_Mongolia_DGS.xml file looks like this:
<datasets>
<Insitu_Surface_Mongolia_DGS name="CEOP Surface Mongolia DGS"
url="Insitu/CAMP_Mongolia_20021001_20030331sfc.data"
doc="">
<properties>
(stuff deleted)
</properties>
<variables>
<Air_Temperature name="Air Temperature" units="Celsius">
<link match="/lasdata/grids/DGS_XYZT_grid"/>
</Air_Temperature>
<Dew_Point_Temperature name="Dew Point Temperature" units="Celsius">
<link match="/lasdata/grids/DGS_XYZT_grid"/>
</Dew_Point_Temperature>
(etc., continues for a total of 19 variables)
</variables>
</Insitu_Surface_Mongolia_DGS>
</datasets>
<grids>
<DGS_XYZT_grid>
<link match="/lasdata/axes/DGS_X"/>
<link match="/lasdata/axes/DGS_Y"/>
<link match="/lasdata/axes/DGS_T"/>
</DGS_XYZT_grid>
</grids>
<axes>
<DGS_X units="degree_east" type="x">
<arange start="106.369" step="1" size="1"/>
</DGS_X>
<DGS_Y units="degree_north" type="y">
<arange start="46.1273" step="1" size="1"/>
</DGS_Y>
<DGS_T units="hours" type="t">
<arange start="2002-Oct-01 01:00:00" step="1" size="48"/>
</DGS_T>
</axes>
The structure "DGS_ . . ." (shown in these next lines):
<link match="/lasdata/grids/DGS_XYZT_grid"/>
<DGS_XYZT_grid>
<link match="/lasdata/axes/DGS_X"/>
<link match="/lasdata/axes/DGS_Y"/>
<link match="/lasdata/axes/DGS_T"/>
</DGS_XYZT_grid>
<DGS_X units="degree_east" type="x">
</DGS_X>
<DGS_Y units="degree_north" type="y">
</DGS_Y>
<DGS_T units="hours" type="t">
</DGS_T>
The structure "DGS_ . . ." has to be unique in each of the 200 files. So if
my include includes all three lines, i.e. if &InsituAirTemperature; includ
es:
<Air_Temperature name="Air Temperature" units="Celsius">
<link match="/lasdata/grids/DGS_XYZT_grid"/>
</Air_Temperature>
then the "DGS_XYZT" part is repeated, and xml doesn't allow repeats of this
in the 200 files.
I want a single copy of the following line identical/repeated in 200 files:
<Air_Temperature name="Air Temperature" units="Celsius">
but I can't have the second line repeated at all:
<link match="/lasdata/grids/DGS_XYZT_grid"/>
I may be stuck with an unfriendly structure. Does anybody see any solutions?
Thank you,
Ben
