Make sure you do this on a test directory structure first. This works
for me, but comes with no guarantees :)
In Workbench, you will need to expose a format attribute to get at this
information.
Open up the properties on the a source feature type, click on the
properties ellipsis (or right-click and select "Properties"). Click on
the "Format Attributes" tab and then check off the fme_dataset
attribute. If you have multiple source features, click on the "Apply to
All" button so that they all have this attribute exposed.
You can extract the path from the fme_dataset with a Grepper. Go into
the Grepper properties, Select the fme_dataset as the attribute, and
enter the following for your regular expression:
^.:\\(.*\\)([^\\]*)$
When you click on OK on the Grepper properties, expand the attribute
section on the MATCHED output. Right-click on the _matched_parts{} and
select Expose Element, choosing to expose 2 elements. _matched_parts{0}
will be (most of) the path, and _matched_parts{1} will be the filename.
The attributes fme_basename and fme_type may also be of use to you.
Once you have these attributes, you can use them to build the attributes
you want to fan out on.
In your case, you will need to perform some specific steps because the
shapefile format only holds a single geometry type per file.
- First, you will want to set up destination feature types for each of
the geometry types you expect to process, and set their allowed geometry
accordingly.
- Second, you will want to make sure that the fme_type attribute is
exposed in all of the source feature types (the first thing you did
above).
- Third, you may want to run this through a SubstringExtractor with
values of 4 and -1 to get rid of the "fme_" in the type attribute.
- Fourth, you will want to run this through a Concatenator. You will
want to concatenate the attribute "fme_basename" with the constant "_"
with the attribute "fme_type" (or the resultant attribute from the
previous step if you chose to do it) into a new attribute (let's call it
"tango" for fun).
- Fifth, you will need to set up a GeometryFilter to place the data into
the correct streams to go to your output features and connect them to
the appropriate features.
- Finally, you will have to set up your output features to do a feature
fanout on the "tango" attribute.
You're still not done though...
Go to the Workspace tab on the left hand side of your screen. Right
click on your shapefile destination dataset (it'll look something like
"filename [SHAPE]" and choose "Fanout Dataset". In "Fanout Prefix",
enter your drive letter like: "D:\". In "Attribute to Fanout on" choose
_matched_parts{0}. Click on OK.
Once again: Make sure you do this on a test directory structure first.
This works for me, but comes with no guarantees :)
*** Note for SAFE: I would have actually done the dataset fanout by
making the drive letter an atom in the regular expression rather than
requiring a hard coded value, but the "Fanout Prefix" attribute does not
seem to accept the value &_matched_parts{0}. Also, Fanout Prefix
requires a value, so I couldn't just leave it off and dump the path into
the attribute. ***

Subject: [fme] FME -how extract source dataset directory attribute
Dear Sir,
Could you pls solve my problem...........
How can I fanout the destination dataset as same as source data set for
ex if i have dgn file in d:\abc\01\*.dgn
d:\abc\02\*.dgn
d:\abc\03\*.dgn
d:\abc\04\*.dgn I have selected all
the *.dgn files from d:\abc directory with sub folder (d:\abc\***\*.dgn)
and I want to translate these dgn files to Esri shape and the
destination directory should be
d:\abc\01\
d:\abc\02\
d:\abc\03\
d:\abc\04\ Now my question is how
can i take attribute for this destination dataset ? what are the
transformers can be used ?
Please if you can answer to this query please reply to me. Your urgent
reply will be highly appreciated.
Thanks.
With Best Regards
