Hi,
I'm setting up an attribute containing a list of files, and then I want to use it as input Dataset in a FeatureReader.
e.g. the attribute contains the string: "C:\\a.jpg","C:\\b.jpg"
The featureReade will reject the attribute as input Dataset
If I hardcode the same string in the FeatureReader Dataset field it works fine.
I also tried to use a workspace runner to convert the attribute to a Published Parameter as input for a reader, but the same problem appears.
Can anyone help me out?

Hi @kath, try this - separate the quoted paths by a whitespace, and surround the entire string with double quotations.
""C:\a.jpg" "C:\b.jpg""
Hi
You will have to remove the quotes around the filename in your attribute before passing it on to the FeatureReader. You can use a StringReplacer for this, set "Text to match" as a double quote (") and leave Replacement text empty.

""C:\a.jpg" "C:\b.jpg""This doesn't work either. My Attribute is now like
C:\\a.jpg,C:\\b.jpg
but it is rejected as well.
Aha, I didn't realize that you had several filenames in the same attribute value.
takashi, that's the solution, thank you!
Good to hear it works.
In fact, that's a "rule of thumb". I can't explain the reason why it works but comma-separated format doesn't work. Hope someone from Safe to clarify this ;)
Hi,
I feel that this post should correspond to what I am trying to do but I do not understand the solution. I want to use a table containing a path attribute and a file name attribute as the source data list.
Thank you.
Should I create a unique string of the form "" C: \\ a.jpg "" C: \\ b.jpg "" ...... ?
Thanks

No need to join the rows into one long list -- just feed the individual rows into the FeatureReader and it will do as you desire.
