Code Snippet: Preprocessing Moveable Type import files for Wordpress

We’ve moved a couple of clients from older Moveable Type installations to Wordpress and each time Wordpress doesn’t handle the text paragraph formating from the Moveable Type import file.  Here is a quick script we created to convert the BODY and EXTENDED BODY sections of the Moveable Type import file to HTML paragraph formatting.

<?php

// TODO: change this to your Moveable Type import filename
$filename = "import.txt";

$inBodyOrExtendedBody = false;
$output = array();

foreach (explode("\n", file_get_contents($filename)) as $line) {
  if ($inBodyOrExtendedBody) {
    $inBodyOrExtendedBody = ($line != "-----");
    if (!$inBodyOrExtendedBody)
      $output[] = "</p>";
  }

  if ($inBodyOrExtendedBody) {
    if (trim($line) == "") {
      $output[] = "</p>";
      $output[] = "<p>";
    }
    else
      $output[] = $line . "<br/>";
  }
  else {
    $output[] = $line;
    $inBodyOrExtendedBody = ($line == "BODY:") ||
                            ($line == "EXTENDED BODY:");
    if ($inBodyOrExtendedBody)
      $output[] = "<p>";
    }
  }

  // remove the trailing <br/> before </p>
  // and the empty paragraphs before outputing
  echo str_replace("<br/>\n</p>", "\n</p>",
                   str_replace("<p>\n</p>", "",
                   implode("\n", $output)));
?>
