[crawfd]

Trying to truncate the results below so that I only read about 5 lines of imported RSS feed .....how can I accomplish this? Thanks

<?

// function that starts code element...



function endElement($parser, $tagName)
{
    global $insideitem, $tag, $title, $description, $link, $pubDate;

    if ($tagName == "ITEM") {
        $trans_tbl = get_html_translation_table (HTML_ENTITIES);
        $trans_tbl = array_flip ($trans_tbl);
        $text = strtr ($description, $trans_tbl);
        echo "<font face=\"Arial\" size=\"2\"><a href='news/index.php?feed=1'><b>$title</b></a> | <a href='news/index.php?feed=1'>more..</a></font><br>";
 $title = $description = $link = $pubDate = $insideitem = false;
        }
    }

$xml_parser = xml_parser_create();

xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");

$fp = fopen($backend, r);

while ($data = fread($fp, 4096)) {
    xml_parse($xml_parser, $data, feof($fp))
    or die(sprintf("XML error: %s at line %d",
            xml_error_string(xml_get_error_code($xml_parser)),
            xml_get_current_line_number($xml_parser)));
}

fclose($fp);
xml_parser_free($xml_parser);

?>
