note 70049 added to ref.xml

First off, I'd like thank all and sundry for providing this excellent resource, it has been very helpful in getting my head around xml parsing. I was recently handed the task of collecting a variety of xml streams, from many different sources and of widely varying quality. If have found that the following function helped parsing the input by cleaning it up. It removes all leading and trailing whitespace and removes carriage returns and linefeeds. Using this function before using xml_parser_create() has helped reduce a number of otherwise unexplainable anomalies, such as arbitrary cutoff of data or the data being divided into two, requiring concatenation. Data longer than 1024 characters still has to be concatenated, but I can live with that. <?php // remove whitespace and linefeeds and returns the name of a temporary file // takes the name of an existing file as a parameter function cleanxmlfile($file, $tmpdir="/tmp", $prefix="xxx_") { $tmp = file_get_contents ($file); $tmp = preg_replace("/^\s+/m","",$tmp); $tmp = preg_replace("/\s+$/m","",$tmp); $tmp = preg_replace("/\r/","",$tmp); $tmp = preg_replace("/\n/","",$tmp); $tmpfname = tempnam($tmpdir, $prefix); $handle = fopen($tmpfname, "w"); fwrite($handle, "$tmp"); fclose($handle); return($tmpfname); } ?> HTH ---- Server IP: 66.163.161.117 Probable Submitter: 89.145.198.59 ---- Manual Page -- http://www.php.net/manual/en/ref.xml.php Edit -- https://master.php.net/note/edit/70049 Del: integrated -- https://master.php.net/note/delete/70049/integrated Del: useless -- https://master.php.net/note/delete/70049/useless Del: bad code -- https://master.php.net/note/delete/70049/bad+code Del: spam -- https://master.php.net/note/delete/70049/spam Del: non-english -- https://master.php.net/note/delete/70049/non-english Del: in docs -- https://master.php.net/note/delete/70049/in+docs Del: other reasons-- https://master.php.net/note/delete/70049 Reject -- https://master.php.net/note/reject/70049 Search -- https://master.php.net/manage/user-notes.php
