I read file geodatabase schema of all feature classes by parsing Definition field XML-s from GDB_Items table. I am using ESRI File GDB API. It's main XML element (for feature class) is DEFeatureClassInfo and then under GPFieldInfoExs element information about each field is stored in GPFieldInfoEx element. Example:
<?xml version="1.0" encoding="utf-8"?>
<DEFeatureClassInfo xsi:type="typens:DEFeatureClassInfo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:typens="http://www.esri.com/schemas/ArcGIS/10.3">
<CatalogPath>\Constructed_Features\Constructed_Feature_pt</CatalogPath>
<Name>Constructed_Feature_pt</Name>
<ChildrenExpanded>false</ChildrenExpanded>
<DatasetType>esriDTFeatureClass</DatasetType>
<DSID>67</DSID>
<Versioned>false</Versioned>
<CanVersion>false</CanVersion>
<ConfigurationKeyword></ConfigurationKeyword>
<RequiredGeodatabaseClientVersion>10.0</RequiredGeodatabaseClientVersion>
<HasOID>true</HasOID>
<OIDFieldName>OBJECTID</OIDFieldName>
<GPFieldInfoExs xsi:type="typens:ArrayOfGPFieldInfoEx">
<GPFieldInfoEx xsi:type="typens:GPFieldInfoEx">
<Name>OBJECTID</Name>
<AliasName>OBJECTID</AliasName>
<ModelName>OBJECTID</ModelName>
<FieldType>esriFieldTypeOID</FieldType>
<IsNullable>false</IsNullable>
<Required>true</Required>
<Editable>false</Editable>
</GPFieldInfoEx>
<GPFieldInfoEx xsi:type="typens:GPFieldInfoEx">
<Name>Shape</Name>
<AliasName>Shape</AliasName>
<ModelName>Shape</ModelName>
<FieldType>esriFieldTypeGeometry</FieldType>
<IsNullable>true</IsNullable>
<Required>true</Required>
</GPFieldInfoEx>
...etc.
However for some file GDBs, upgraded from 9.3 version to 10.3, not all fields are listed (under own GPFieldInfoEx element), I see only part of them.
Do you know a way how to repair such file GDBs so definitions include all tables fields?
I tried to add new fields; they are appended, but those missing fields still do not appear.
I also tried to create new file GDB using ArcCatalog 10.3; field edits appear under GPFieldInfoExs correctly.
EDIT: Also tried to export full gdb to XML workspace document with data and import to empty gdb but this did not help.
