PDFlib TET PDF IFilter 4.0 Manual

4 XML Configuration File
4.1 Working with Configuration Files
The operation of TET PDF IFilter can be controlled with an XML configuration file. A
sample configuration file is installed with TET PDF IFilter.
Specifying the location of the configuration file. The configuration file can be specified
in the following registry key which contains a String value with the full path name
of the configuration file:
HKEY_LOCAL_MACHINE\SOFTWARE\PDFlib\TET PDF IFilter4\configfile
Note It is recommended to place XML configuration files outside the installation directory of
TET PDF IFilter. This way the configuration will survive if the installation directory changes, e.g.
after installing an updated version of TET PDF IFilter.
If this registry entry does not exist or contains an empty string, the default configuration
will be used. If the configuration file specified in the registry entry cannot be
opened, a warning will be written to the application event log, and the default configuration
will be used for indexing. If XML parsing of the configuration file fails, a warning
will be written to the event log, and no indexing will be done.
Note The installer will not create a registry entry for a configuration file. This must be done by the
user if required.
Only a single configuration file can be used for TET PDF IFilter on a machine. However,
the 32-bit and 64-bit versions can use different configuration files on the same machine
since the above registry entry will be searched in the 32-bit and 64-bit registry, respectively.
If you changed the configuration file you must rebuild the index for the changes to
become active.
Predefined XML configuration files. Several predefined configuration files are installed
with TET PDF IFilter:
> The file default.xml describes the internal default settings of TET PDF IFilter. It may
serve as a starting point for creating a customized configuration file.
> The file starter.xml contains property definitions which can be used with the starter
samples that are installed with TET PDF IFilter.
XML namespace and schema description. Table 4.1 lists the elements and attributes
which are available in the XML configuration file. The namespace URI for the XML configuration
is
http://www.pdflib.com/XML/TET_PDF_IFilter3/TET_PDF_IFilter_Config-3.0.xsd
Note The schema namespace URI and download location contain the version number 3 since the
current schema is compatible with the schema used in TET PDF IFilter 3.0.
