WordPress export…without access to phpMyAdmin

Hi All-
Forgive me if this question has been answered elsewhere, but I’m couldn’t find an answer.

I have a word press blog that is hosted on a domain name owned by someone else. I am the sole author and would like to transfer the content on the blog to my own website, where I have recently installed word press.

Because I do not have access to the install process, any can only post, I cannot log onto phpMyAdmin or export, backup, etc. any of my files.

My question is this – is there a way for me to export my entries in any other way (besides the time consuming entry-by-entry copy/pasting). I don’t even care about saving the tags, categories, etc. at this point – I just want to make sure the content doesn’t vanish when the domain name expires in, oh, 24 hours.

Thanks in advance.
