How to export xml from PDF form in adobe reader?

Hi Every one!

I need to export xml from PDF form using Adobe reader. Can any one help me on this?

Actually Adobe acrobat having built-in option as "Export XML". But in reader there is no option like that. But I can able to get the exported XML using submit button. But without using button/Adobe work bench what are all the possibilities to get it?

Please help me on this.

Thanks,

Susila
