Extract from URL field in beamer

Question

How can I extract the value of the URL field of an entry in a .bib file? I want to print it directly in the frame of my beamer document.

Additional info: (added July 20, 2014):

I can't provide the exact copy of the .tex file because it's very long now. In my preamble I have

\usepackage{natbib,hyperref}
\usepackage{bibentry}
\bibliographystyle{apalike}

and in the document I have

 \begin{document}
 \nobibliography{database}
 .... 

 \citet{Jilvero2012} % I want to print the URL here%

 ...
 \end{document}

this key is defined in my .bib file as

@Article{Jilvero2012,
   Title                    = {Heat requirement for regeneration of aqueous ammonia in post-combustion carbon dioxide capture },
   Author                   = {Henrik Jilvero and Fredrik Normann and Klas Andersson and Filip Johnsson},
   Journal                  = {International Journal of Greenhouse Gas Control },
   Year                     = {2012},
   Number                   = {0},
  Pages                    = {181 - 187},
   Volume                   = {11},

  Doi                      = {http://dx.doi.org/10.1016/j.ijggc.2012.08.005},
  ISSN                     = {1750-5836},
  Keywords                 = {Chilled ammonia},
   Url                      = {http://www.sciencedirect.com/science/article/pii/S1750583612001909}
 }

Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. — Heiko Oberdiek, Jul 19 '14 at 10:41
You can use the package usebib: http://www.ctan.org/pkg/usebib — Marco Daniel, Jul 19 '14 at 11:32
This procedure requires me to change the format of my bib file and I have a big bib file so its not practical for me to do so. The documentation also cautions the use of usebib for large bib files. But thanks a lot! — texsmitten, Jul 19 '14 at 12:23
Have you seen beamer and natbib? Can you provide the community with a minimal working example (MWE)? — Werner, Jul 19 '14 at 19:32
Why not biblatex? Regarding usebib, if your .bib file uses " for delimiting fields, you're out of luck, because usebib employs TeX macros for doing its job and, since " is a valid character in fields, there's not much one can do about it. — egreg, Jul 19 '14 at 21:13
Yes @werner. Actually I have another related question in this group.

Using biblatex, \citeurl{<bibkey>} will print the URL associated with the citation key <bibkey>:

enter image description here

\documentclass{beamer}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@Article{Jilvero2012,
   Title                    = {Heat requirement for regeneration of aqueous ammonia in post-combustion carbon dioxide capture },
   Author                   = {Henrik Jilvero and Fredrik Normann and Klas Andersson and Filip Johnsson},
   Journal                  = {International Journal of Greenhouse Gas Control },
   Year                     = {2012},
   Number                   = {0},
  Pages                    = {181 - 187},
   Volume                   = {11},

  Doi                      = {http://dx.doi.org/10.1016/j.ijggc.2012.08.005},
  ISSN                     = {1750-5836},
  Keywords                 = {Chilled ammonia},
   Url                      = {http://www.sciencedirect.com/science/article/pii/S1750583612001909}
 }
\end{filecontents*}
\usepackage[backend=biber]{biblatex}
\usepackage{hyperref}

\addbibresource{\jobname.bib}
\begin{document}

\begin{frame}
  \cite{Jilvero2012}

  \citeurl{Jilvero2012}
\end{frame}

\begin{frame}
  \printbibliography
\end{frame}

\end{document}

You can also work with BibTeX by passing the option backend=bibtex to biblatex at loading time.

Great!!! It's working now! I just used the backend=bibtex! Many thanks @Werner — texsmitten, Jul 20 '14 at 20:46
