Your Problem 1 regarding:
The "xsi:nil = "true" is the different and when I deleted this text, this error disappear.
How can I prevent this text appear when I export AIXM or I have to delete it manually?
Is there any field that I must input the data to prevent this text appear?
You can remove this text from your 51ExportTemplate.xml. This file is found at: C:\Program Files (x86)\ArcGIS\AviationCharting\Desktop10.8\DataExchange\AIXM\Exporter\51\51ExportTemplate.xml
Find all 5 (FATO, RWY, TWY, APRON, TLOF) lines like:
<aixm:associatedAirportHeliport removeIfEmptyAttribute="href" xlink:href="{adhp.clientkey_id}" xsi:nil="true"/>
and remove xsi:nil="true", so they are like this:
<aixm:associatedAirportHeliport removeIfEmptyAttribute="href" xlink:href="{adhp.clientkey_id}"/>
We are still looking into why we include this in the template, but we had not seen validation errors because of it, before.
Can you tell me what program is giving you the error? ( You said "I import exported AIXM file from ArcGIS to another program it show error as below")
Thanks
