When you import posts with the standard WP Importer plugin, most users are going to find that it changes the standard paragraph break sequence of \n\n to a single \n. When it comes time to display the post later, this will prevent wpautop() from wrapping consecutive paragraphs in <p>...</p> tags, instead replacing the break between them with a <br />.

Reset to default 1I banged my head on the wall for hours before I realized there was a simple solution I could use to pre-process the import XML file prior to running WP Importer. The solution is to just run the file through a home-grown filter program that runs wpautop() on the content before it has a chance to get munged by the plugin.
Since getting the content blocks out of the input XML is a little tedious, I decided to share my code with the community to kick-start your next import. The code and a lengthier explanation are at "WordPress import with wpautop". I'll include the PHP code here for preservation within StackExchange:
$accum = 0;
$buffer = '';
while ( $line = fgets( STDIN ) ) {
$line = preg_replace( '/\r\n/', "\n", $line );
$line = preg_replace( '/\r/', "\n", $line );
$start = false;
$end = false;
if ( preg_match( '/^\s*<content:encoded><!\[CDATA\[/', $line ) ) {
$line = preg_replace( '/^\s*<content:encoded><!\[CDATA\[/', '', $line );
$start = true;
}
if ( preg_match( '/\]\]><\/content:encoded>\s*$/i', $line ) ) {
$line = preg_replace( '/\]\]><\/content:encoded>\s*$/i', '', $line );
$end = true;
}
if ( $start && $end ) {
echo $line;
} elseif ( $start ) {
$accum = true;
$buffer = $line;
} elseif ( $end ) {
$accum = false;
$buffer .= $line;
echo '<content:encoded><![CDATA[' . wpautop( $buffer ) . ']]></content:encoded>';
} else {
if ( $accum ) {
$buffer .= $line;
} else {
echo $line;
}
}
}
exit(0);
This technique relies on being able to run wpautop() from inside a plain ol' command line program. See "Using WordPress in a non-interactive 'batch' CLI process" for details on how to do that.
