Expat is a SAX parser. It can handle blocks (or streams as they're preferred to be called these days) and doesn't care whether a document is valid or even when it is a document. The point of using a stream-based parser, is that you're not required to open up files entirely (in fact - your input can be a socket). Allthough the manual example dies, as soon as a parser error is detected, one can actually retrieve the linenumber of the error, store everything from that line on in a buffer, process the lines before that and retrieve the next block, appending it to the buffer. So I agree, the example is not very useful in some cases, but not for your reasoning. Previous Comments: ------------------------------------------------------------------------ [2002-10-11 08:01:36] [EMAIL PROTECTED] URL: http://www.php.net/manual/en/ref.xml.php how the files are opened is not the correct way or the input/output may get mixed up or truncated on same cases... I mean ... you should not open files in blocks, but whole file ... I copy pasted your example to my code and when some block (of those 4096 bytes) end and next blocks start value somehow happened to be in the middle XML value, then the value was truncated or cutted half in output. anyway the input (cycle) should be in one piece (whole file at once) or row by row, not by constant number of bytes. Example 1. (your version) $file = "data.xml"; $depth = array(); function startElement($parser, $name, $attrs) { global $depth; for ($i = 0; $i < $depth[$parser]; $i++) { print " "; } print "$name\n"; $depth[$parser]++; } function endElement($parser, $name) { global $depth; $depth[$parser]--; } $xml_parser = xml_parser_create(); xml_set_element_handler($xml_parser, "startElement", "endElement"); if (!($fp = fopen($file, "r"))) { die("could not open XML input"); } while ($data = fread($fp, 4096)) { if (!xml_parse($xml_parser, $data, feof($fp))) { die(sprintf("XML error: %s at line %d", xml_error_string(xml_get_error_code($xml_parser)), xml_get_current_line_number($xml_parser))); } } xml_parser_free($xml_parser); BUT THIS SHOULD BE (my version): Example 1. $file = "data.xml"; $depth = array(); function startElement($parser, $name, $attrs) { global $depth; for ($i = 0; $i < $depth[$parser]; $i++) { print " "; } print "$name\n"; $depth[$parser]++; } function endElement($parser, $name) { global $depth; $depth[$parser]--; } $xml_parser = xml_parser_create(); xml_set_element_handler($xml_parser, "startElement", "endElement"); if (!($fp = fopen($file, "r"))) { die("could not open XML input"); } $data = fread($fp, filesize($file))); if (!xml_parse($xml_parser, $data, feof($fp))) { die(sprintf("XML error: %s at line %d", xml_error_string(xml_get_error_code($xml_parser)), xml_get_current_line_number($xml_parser))); } xml_parser_free($xml_parser); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19862&edit=1 -- PHP Documentation Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
