Document Grabber: How to just get the "Number of Results"

Hi All,

I would like to query Pubmed with 50,000+ queries, but I just want the hit counts (Number of results for all queries) not the whole text.

Is it possible?

 

Thanks,

Sanatan

Any help is really appriciated.

Hi Sanatan,

you can do this with the Palladian nodes (HTTP Retriever and HTML Parser) in combination with the XML nodes (X Path).

Create a URL with the query attached and use the HTTP Retriever to connect to PubMed and download the result page. Parse the reulst page and extract the "count" value, related to the query. Attached is an example workflow with some example queries.
