There is probably a relation with an issue
https://issues.apache.org/jira/browse/SOLR-4875
> Problem with xpath and attributes
> ---------------------------------
>
> Key: SOLR-5809
> URL: https://issues.apache.org/jira/browse/SOLR-5809
> Project: Solr
> Issue Type: Bug
> Components: contrib - DataImportHandler
> Affects Versions: 4.6
> Reporter: Jan Mach
> Priority: Critical
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> There is a strange behavior, when I use in XPathEntityProcessor, in xpath for
> multiple fields, rules with attributes for the same tag or when I would like
> to select the same tag in xpath twice.
> My XML looks like:
> <?xml version="1.0" encoding="utf-8"?>
> <metadata>
> <id>1</id>
> <fileProperties fileType="a">a.pdf</fileProperties>
> <fileProperties fileType="b">b.pdf</fileProperties>
> <fileProperties fileType="c">c.pdf</fileProperties>
> </metadata>
> What works fine:
> <field column="test_value" xpath="/metadata/fileProperties"
> multiValued="true" />
> <field column="test_fileType" xpath="/metadata/fileProperties/@fileType"
> multiValued="true" />
> The result:
> test_value="a.pdf","b.pdf","c.pdf" (correct)
> test_fileType="a","b","c" (correct)
>
> What is wrong 1):
> When I add a new column (test_fileID) with selecting with an attribute,
> test_value and test_fileType have wrong values.
> <field column="test_fileID"
> xpath="/metadata/fileProperties[@fileType='a']/@fileType" />
> <field column="test_value" xpath="/metadata/fileProperties" />
> <field column="test_fileType" xpath="/metadata/fileProperties/@fileType" />
> The result:
> test_fileID="a" (correct)
> test_value="b.pdf","c.pdf" (missing "a.pdf")
> test_fileType="b","c" (missing "a")
> What is wrong 2):
> I cannot select the same field value twice.
> <field column="test_one" xpath="/metadata/fileProperties"
> multiValued="true"/>
> <field column="test_two" xpath="/metadata/fileProperties]"
> multiValued="true"/>
> The result:
> test_one: (the field is missing, should
> be "a.pdf","b.pdf","c.pdf")
> test_two: "a.pdf","b.pdf","c.pdf" (correct)
