ID: 37622 Updated by: tony2001@php.net Reported By: nickm at tbms dot ru -Status: Open +Status: Bogus Bug Type: DOM XML related Operating System: Windows XP SP2 PHP Version: 5.1.4 New Comment: . Previous Comments: ------------------------------------------------------------------------ [2006-05-29 10:00:15] nickm at tbms dot ru I ve localized the code from my framework and it gives errors now. Seems to me that the problem is in the QUERY. But on thing is still confusing me why the QUERY works via the http://www.activsoftware.com/xml/xpath/ processor and some others? ------------------------------------------------------------------------ [2006-05-29 09:30:00] tony2001@php.net Warning: DOMXPath::query(): Invalid expression in /tmp/3.php on line 5 Warning: DOMXPath::query(): Invalid expression in /tmp/3.php on line 5 bool(false) Did you try to enable display_errors ? ------------------------------------------------------------------------ [2006-05-29 09:09:49] nickm at tbms dot ru Here is the code: <? $document = new DOMDocument("1.0", "utf-8"); $document->load("http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml"); $xPath = new DOMXPath($document); $result = $xPath->query("/gesmes:Envelope/:Cube/:Cube/:Cube[@currency='USD']"); //Oops! $result is somehow empty if ($result->length > 0) { print "OK!"; } else { print "ERROR!"; } ?> ------------------------------------------------------------------------ [2006-05-29 08:59:14] tony2001@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2006-05-29 08:47:11] nickm at tbms dot ru Description: ------------ I've tried to execute the "/gesmes:Envelope/:Cube/:Cube/:Cube[@currency='USD']" XPath instruction via the DOMXPath->query method on the "http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml" but I got neither parse error nor the DOMNodeList. The result is simply empty. I validated my istruction here: "http://www.activsoftware.com/xml/xpath/" &#1040;nd it get exactly what I want from the XML document. Reproduce code: --------------- $from = "USD"; $result = $xPath->query("/gesmes:Envelope/:Cube/:Cube/:Cube[@currency='" . strtoupper($from) . "']"); //$result is EMPTY! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37622&edit=1
