Previous Comments: ------------------------------------------------------------------------ [2008-12-26 19:54:10] felipe@php.net Hello, the dot character only match a newline in a string when using the 's' modifier. Try: /(<\?xml.+<report[^>]+>)/s PS: You don't need escape < > in this case (that it's not a separator (the / in this case)) ------------------------------------------------------------------------ [2008-12-26 19:16:53] victor at casnt dot ro Description: ------------ The exact same pattern matching is not working on the same string, with a extra line at the end. The length of the string seems to be the problem. Reproduce code: --------------- The script: $handle = fopen('test3.xml', "r"); $contents = fread($handle, filesize('test3.xml')); fclose($handle); $contents = preg_replace('/\>[\t|\ |\s]{1,}\</', "><", $contents); $contents = preg_replace('/\n/', "", $contents); if(preg_match('/(\<\?xml.{1,}\<report[^>]{1,}\>)/', $contents, $match)) { print "Match: $match[1]\n"; } else {print "Fail\n";} OBSERVATION: If you delete the last line from the file test3.xml, the pattern matching will work fine. The last lines have nothing to do with the pattern. You can find the file here: http://www.casnt.ro/Files/XML/test3.xml Expected result: ---------------- Match: <?xml version="1.0" encoding="utf-8"?><report AppKey="CNAS-v1.0.2801.665" AppID="14" clinic="SSSSSSSSSSSSSSSSSSSSSS" fiscalCode="11111111" contractNo="123123123/2008" insuranceHouse="CAS-NT" reportingDate="2008-12-07" startFrom="2008-11-01" endTo="2008-11-30" invoiceNo="" labValue="0" hspValue="0" xmlns="http://localhost"> Actual result: -------------- Fail ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46947&edit=1
