Well, that makes things easier. If we can exclude some complications 
like CDATA, HTML comments and nested <p> tags, then it might be indeed 
possible to use regex to extract some content.

Be sure to use a non-greedy regex to match the closest end tag </p>, and 
the equivalent of /s or dotall for '.' to match newlines (or use 
(.|\r|\n) instead of dot). This seems to work at first glance:

grep -Po '<p (.|\r|\n)*?</p>' abc.xhtml

(-P is needed for grep to support non-greedy search).
