Can I do content based polling in Biztalk server using WSS Adapter

I have scenario where I have to poll documents from sharepoint library based on some condition开发者_Go百科s. e.g. fetch documents which has status==Readytoprocess and then based upon unique number present in document fetch its content file from another sharepoint library.

What is the best approach doing in biztalk? Is there any way where I can create Dynamic Receive?

1. Create a view in Sharepoint, with a status==Readytoprocess-filter, and let BizTalk poll from there.
   1. Make a request to the Sharepoint service for the content file.
