Hi Andrew,
my experience with XPathEntityProcessor is non-existent. ;-)
Just after a quick look at the method that throws the exception:
private void addField0(String xpath, String name, boolean multiValued,
boolean isRecord) {
List<String> paths = new
LinkedList<String>(Arrays.asList(xpath.split("/")));
if ("".equals(paths.get(0).trim()))
paths.remove(0);
rootNode.build(paths, name, multiValued, isRecord);
}
and your foreach attribute value in combination with the xpath:
> forEach="/">
> <field column="content"
>
xpath="//*[local-name()='structCategory']/*[local-name()='struct']/*[local-name()='title']"
> />
I would guess that the double slash at the beginning is not working with
your foreach regex. I don't know whether this is something the processor
should expect and handle correctly or whether you have to take care of
in your configuration.
Cheers,
Chantal

Hi Andrew,
your inner entity uses an XML type datasource. The default entity
processor is the SQL one, however.
For your inner entity, you have to specify the correct entity processor
explicitly. You do that by adding the attribute "processor", and the
value is the classname of the processor you want to use.
e.g. <entity dataSource="filesystem" name="domain_pdb"
processor="XPathEntityProcessor" ....
Thanks -- I was also missing a forEach expression -- in my case, just "/"
since each XML file contains the information for no more than one document.
However, I'm now getting a different exception:

My data config now looks like this:

tables are available there -->

as id, 'PDB code ' || pdb_code || ', chain ' || chain_code || ', domain ' ||
domain_code as title, pdb_code || ',' || chain_id as related_ids, 'domain'

<field column="content"

</entity>
</entity>
</document>

Thanks in advance, again :-)
Andrew.
