Investigation+of+automatic+pmid+and+doi+recognition+software+031513

Emailed Endnote, zotero, and Mendeley -email { Often when I write a document I don't want to deal with any reference software so I just put the Pubmed ID (PMID) or doi (digital object identifier) in parenthesis in text in the document. Then later I go back with Zotero or Endnote Web and see what document I wanted to reference there, add this to my library, and then insert the reference. Do you know of any way or any software to automatically recognize pubmed ids within a bunch of text and then put the appropriate references there?

Thanks for any help and information you have to offer me! - }
