note 55360 added to function.xml-set-element-handler

I noticed that in the example below, and all the examples I've seen on this site for viewing xml in html, the look of self closing tags such as <br /> are not preserved. The parser cannot distinguish between <tag /> and <tag></tag>, and if your start and end element functions are like these examples, both instances will be output with both an indvidual start and end tag. I needed to preserve self-closing tags and it took me a while to figure out this work around. Hope this helps someone... The start tag is left open, and then completed by it's first child, the next start tag or its end tag. The end tag will complete with " />", or </tag> depending on the number of bytes between the start and end tags in the parsed data. <?php //$data=filepath or string $data=<<<DATA <normal_tag> <self_close_tag /> data <normal_tag>data <self_close_tag attr="value" /> </normal_tag> data <normal_tag></normal_tag> </normal_tag> DATA; function startElement($parser, $name, $attrs) { xml_set_character_data_handler($parser, "characterData"); global $first_child, $start_byte; if($first_child) //close start tag if neccessary echo "><br />"; $first_child=true; $start_byte=xml_get_current_byte_index ($parser); if(count($attrs)>=1){ foreach($attrs as $x=>$y){ $attr_string .= " $x=\"$y\""; } } echo htmlentities("<{$name}{$attr_string}"); //unclosed starttag } function endElement($parser, $name) { global $first_child, $start_byte; $byte=xml_get_current_byte_index ($parser); if($byte-$start_byte>2){ //if end tag is more than 2 bytes from start tag if($first_child) //close start tag if neccessary echo "><br />"; echo htmlentities("</{$name}>")."<br />"; //individual end tag }else echo " /><br />"; // self closing tag $first_child=false; } function characterData($parser, $data) { global $first_child; if($first_child) //if $data is first child, close start tag echo "><br />"; if($data=trim($data)) echo "<font color='blue'>$data</font><br />"; $first_child=false; } function ParseData($data) { $xml_parser = xml_parser_create(); xml_set_element_handler($xml_parser, "startElement", "endElement"); xml_parser_set_option($xml_parser,XML_OPTION_CASE_FOLDING,0); if(is_file($data)) { if (!($fp = fopen($file, "r"))) { die("could not open XML input"); } while ($data = fread($fp, 4096)) { if (!xml_parse($xml_parser, $data, feof($fp))) { $error=xml_error_string(xml_get_error_code($xml_parser)); $line=xml_get_current_line_number($xml_parser); die(sprintf("XML error: %s at line %d",$error,$line)); } } }else{ if (!xml_parse($xml_parser, $data, 1)) { $error=xml_error_string(xml_get_error_code($xml_parser)); $line=xml_get_current_line_number($xml_parser); die(sprintf("XML error: %s at line %d",$error,$line)); } } xml_parser_free($xml_parser); } ParseData($data); ?> ---- Submitter IP: 62.236.74.67 ---- Manual Page -- http://www.php.net/manual/en/function.xml-set-element-handler.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55360 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55360&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55360&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55360&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55360&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55360&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55360&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55360&report=yes Search -- http://master.php.net/manage/user-notes.php
