Re: DIH doesn't handle bound namespaces?

[P Williams <wi...@gmail.com>]

Hi Gary,

From
http://wiki.apache.org/solr/DataImportHandler#Usage_with_XML.2BAC8-HTTP_Datasource

*It does not support namespaces , but it can handle xmls with namespaces .
When you provide the xpath, just drop the namespace and give the rest (eg
if the tag is '<dc:subject>' the mapping should just
contain 'subject').Easy, isn't it? And you didn't need to write one line of
code! Enjoy **
*
You should be able to use xpath="//titleInfo/title" without making any
modifications (removing the namespace) to your xml.

I hope that answers your question.

Regards,
Tricia

Yes, the xpath thing is a custom lightweight thing for high-speed use.

There is a separate full XSL processor.
http://wiki.apache.org/solr/DataImportHandler#Configuration_in_data-config.xml-1

I think this lets you run real XSL on input files. I assume it lets you
throw in your favorite XSL implementation.

: *It does not support namespaces , but it can handle xmls with namespaces .

The real crux of hte issue is that XPathEntityProcessor is terribly named.  
it should have been called "LimitedXPathishSyntaxEntityProcessor" or 
something like that because it doesn't support full xpath syntax...

"The XPathEntityProcessor implements a streaming parser which supports a 
subset of xpath syntax. Complete xpath syntax is not supported but most of 
the common use cases are covered..."

...i thought there was a DIH FAQ about this, but if not there really 
should be.
