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:
<dataConfig>
<!-- TODO change this back to v3.3.0 when the appropriate mapping
tables are available there -->
<dataSource name="database" driver="org.postgresql.Driver"
url="jdbc:postgresql://cathdb.info/cathdb_v3_2_0" user="***" password="***"
/>
<dataSource name="filesystem" type="FileDataSource"
basePath="/cath/people/cathdata/v3_3_0/pdb-XML-noatom/" encoding="UTF-8"
connectionTimeout="5000" readTimeout="10000"/>
<document name="domain">
<entity name="domain" dataSource="database" query="select domain_id
as id, 'PDB code ' || pdb_code || ', chain ' || chain_code || ', domain ' ||
domain_code as title, pdb_code || ',' || chain_id as related_ids, 'domain'
as doc_type, pdb_code from domain">
<entity dataSource="filesystem" name="domain_pdb"
url="${domain.pdb_code}-noatom.xml" processor="XPathEntityProcessor"
forEach="/">
<field column="content"
xpath="//*[local-name()='structCategory']/*[local-name()='struct']/*[local-name()='title']"
/>
</entity>
</entity>
</document>
</dataConfig>
Thanks in advance, again :-)
