 Hi, 

I am having an issue with feature readers and XML. I have a process which downloads an XML file from an ftp site, and the file name changes daily.  Upon download, I am trying to trigger a second process which reads the downloaded xml, so I can then split it into separate records (hence why reading in as text will not work, as I need the xml fragments). I use a path reader, to get the file name, but when I put ‘Path_Windows’ as the dataset, i get this error: 

error message

 

 

If I choose to ignore the message, and run to the featurereader, It reads in the correct amount of records (59), but the schema is blank. 

Blank Schema

 

Log Error message

 

 

 

Now, i know for a fact that my xml does in fact, have a schema, because if I hard code the file name in the feature reader, it works perfectly fine. (see below)

 

 

 

FeatureReader with hard coded file name
Successfully read

 

The parameters are identical on both.

I am at a total loss as to why when I want to put in a dynamic file name, the whole process falls over. If I was just writing the xml out, I would read it in as a txt file as a work around, but because I need to process the xml a certain way, i need those xml fragments in order to get my desired output. 

 

 

I am in no way an xml expert, so any help would be appreciated!

This is because, if you use a dynamic filename, the schema is unknown. You can use an AttributeExposer to expose the unexposed attributes. You can simply choose import, import from feature cache.

Thank you so much! I exposed the xml_fragment from the cache, and this has worked perfectly :) 

 

Cheers :)

In my opinion, FME works best with 2 screens. One for the workflow, one for the results. Then the log is not hidden behind the visual preview window and when you select a feature, you can see the unexposed attributes in the Feature Information window.

You can configure this via Tools, FME Options, Data Inspection, Inspect with Data Inspector when Visual Preview window closed.
