Rui CarmoThe following PHP functions (designed as class members) can parse (and write) OPML files in a way NetNewsWire can understand:
function parse( $szFilename ) {
assert( file_exists( $szFilename ) );
$oParser = xml_parser_create("ISO-8859-1");
$szData = implode( "",file($szFilename) );
xml_parse_into_struct( $oParser, $szData, $aValues );
foreach( $aValues as $aElement ) {
if( $aElement["tag"] === "OUTLINE" ) {
$szGUID = md5($aElement["attributes"]["XMLURL"]);
$this->m_aData[$szGUID] = $aElement["attributes"];
}
}
xml_parser_free( $oParser );
} // parse function serialize( $szFilename ) {
$hFile = fopen( $szFilename, "w" );
fputs( $hFile, '<?xml version="1.0" encoding="ISO-8859-1"?>' . "\n" );
fputs( $hFile, "<opml>\n <body>\n" );
foreach( $this->m_aData as $aElement ) {
$szBuffer = " <outline ";
foreach( $aElement as $szAttribute => $szValue ) {
$szAttribute = strtolower( $szAttribute );
$szAttribute = str_replace( "url", "Url", $szAttribute ); // readable names
$szValue = htmlentities( $szValue, ENT_COMPAT, "ISO-8859-1" );
// Pack \n and \r (usually inside DESCRIPTION attributes)
$szValue = strtr($szValue, array("\n" => "
", "\r" => "
"));
$szBuffer .= "$szAttribute=\"$szValue\" ";
}
$szBuffer .= "/>\n";
fputs( $hFile, $szBuffer );
}
fputs( $hFile, " </body>\n</opml>" );
fclose( $hFile );
} // serialize
