CrossRef Metadata Exporting?

Hello,

I am working on the academic journal Imaginations: Journal of Cross Cultural Image Studies (www3.csj.ualberta.ca/imaginations), and we are looking to assign DOI codes to our articles through CrossRef. I am wondering if there is a WordPress 4.0-compatible (or other versions!) plugin that will export the metadata from our articles in a CrossRef-compatible XML file?

Any tips or pointers would be appreciated!
