Tags not importing when using WordPress import system

Save the xml snippet to a xml file. And after seeing the message Failed to import post tag (after importing all the posts) import this file. It will import all the tags.

Here is your xml

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:excerpt="http://wordpress.org/export/1.2/excerpt/" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:wfw="http://wellformedweb.org/CommentAPI/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:wp="http://wordpress.org/export/1.2/">
