Re: XPath with ExtractingRequestHandler

[Arcadius Ahouansou]

Hi Mike.

I am going through this too.

How did you solve this?

Thanks.

Arcadius.

 Yeah, I tried:

 also tried

 //xhtml:div[@class='**bibliographicData']

 Neither worked.  The DIV I need also had an ID value, and I tried both
 variations on ID as well.  Still nothing.


 XPath handling for Tika seems to be pretty basic and does not seem to
 support most XPath Query syntax.  Probably because it's using a Sax parser,
 I don't know.  I guess I will have to write something custom to get it to
 do what I need it to.

 Thanks for the reply though.

 I will post a follow up with how I fixed this.

Hi,

maybe I am wrong, but the // should be at the beggining of the
expression, like
//xhtml:div[@class='bibliographicData']/descendant:node(),
or if you want to search the div inside body, you have to use descendant like
/xhtml:html/xhtml:body/descendant::xhtml:div[@class='bibliographicData']/descendant:node()

2011/12/14 Michael Kelleher mj.kelle...@gmail.com:
 I want to restrict the HTML that is returned by Tika to basically:


  /xhtml:html/xhtml:body//xhtml:div[@class='bibliographicData']/descendant:node()


 and it seems that the XPath class being used does not support the '//'
 syntax.

 Is there anyway to configure Tika to use a different XPath evaluation class?
