I open them in wordpad or Word or some xml reader, they are digitally paraphrased.

I understand your situation, just is there any method/software to reduce

"wp:wxr_version>1.1</wp:wxr_version>
<wp:multisite>
<wp:xanga_user_id>xxxxxx3</wp:xanga_user_id>
<wp:site_title>xxxxi's Xanga Site</wp:site_title>
<wp:site_address>xxxxx</wp:site_address>"

to my original words without those technical things?

Thanks.
