<?php 
/**
 * Cli process that gets as 1st argument the output of tesseract ... hocr and dumps 
 * its text nodes
 */
$inFile = $argv[1];
$outFile = $argv[2];
$stream = file_get_contents($inFile);
$dom = DOMDocument::loadHTML($stream);
$out = array();
foreach ($dom->getElementsByTagName('p') as $tag) {
    $out[] = $tag->nodeValue;
}

file_put_contents($outFile, implode("\n", $out));
